    In: Advanced Materials Research, Trans Tech Publications, Ltd., Vol. 154-155 ( 2010-10), p. 287-291
    Abstract: In this paper a Lab-On-Chip device using negative dielectrophoresis has been proposed for the focusing of particles at the center of the micro-channel. A 3D computational model was presented to simulate the focusing process. In particular, the model will solve for bioparticle movement and Joule heating. In the experimental study, the mixture of viable and nonviable yeast cells was used to demonstrate the focusing effect of the designed microfluidic device. The fabricated chip performs a desired focusing result for the conditions with the electric fields frequency of 1MHz, the medium conductivity of and the applied voltage , which validities the proposed 3D computational model. This Lab-On-Chip device provides a simple and effective mean of particle focusing.

    In: Advanced Materials Research, Trans Tech Publications, Ltd., Vol. 664 ( 2013-2), p. 55-58
    Abstract: In this paper, the soil simulation pot experiment was carried out. The self-made cadmium (Cd) and lead (Pb) compound contaminated soil was taken as the test soil, and wheat was taken as the test plant. The Cd and Pb concentrations in different parts of wheat under jointing stage, booting stage, flowering stage, and mature period were measured, and enrichment characteristics of wheat to Cd and Pb under different growth stages were analyzed. The results showed that Cd and Pb contents in wheat roots were the greatest, while the contents in nutritive organ seeds were the least. Sequence of Cd and Pb contents in various parts of wheat was: roots 〉 stems & leaves 〉 rice husks 〉 seeds. Cd and Pb contents in various parts of wheat plant gradually grew in the entire growth period, which reached the maximum at mature stage. According to the transfer coefficient and enrichment factor analysis, ability of wheat roots to enrich heavy metals Cd and Pb was stronger than that of stems & leaves, rice husks and seeds. In the transfer process of heavy metals Cd and Pb from soil to root, the transfer ability sequence was Cd 〉 Pb.

    In: Advanced Materials Research, Trans Tech Publications, Ltd., Vol. 726-731 ( 2013-8), p. 387-391
    Abstract: In this paper, two kinds of different pollution degree soils denoted as L1 and L2 were used as test soils. Desorption experiment was carried out to study the impacts of pH and electrolyte on desorption characteristics of cadmium (Cd) in soils. The results showed that the variation trends of Cd desorption rates with increase in pH were similar. In other words, it decreased as pH increased. In acidic region, desorption rate of heavy metal Cd decreased rapidly as pH increased. When pH = 4, Cd desorption rate was largest; in neutral and alkaline regions (pH = 7-10), desorption rate of heavy metal Cd decreased slowly as pH increases. Cd desorption behavior was closely related to type and concentration of electrolyte. Under the same concentration, Cd desorption capabilities of three electrolytes in soils L1 and L2 could be expressed in following order: CaCl 2 〉 Ca (NO 3 ) 2 〉 NaCl.

    Impacts of Trace Elements Iron and Zinc on Phytoavailability of Heavy Metals Cadmium and Lead
    Trans Tech Publications, Ltd. ; 2013
    In:  Advanced Materials Research Vol. 664 ( 2013-2), p. 504-509

    In: Advanced Materials Research, Trans Tech Publications, Ltd., Vol. 664 ( 2013-2), p. 504-509
    Abstract: In this paper, the soil simulation pot experiment was carried out to study the impacts of trace elements iron (Fe) and zinc (Zn) on availability of cadmium (Cd) and lead (Pb). The self-made Cd and Pb compound contaminated soil was taken as the test soil, and wheat was taken as the test plant. The results show that with the increase in Fe dosage, overground dry weight, root dry weight, and total dry weight of wheat gradually increase; the application of Zn reduces overground dry weight, root dry weight, and total dry weight of wheat. Meanwhile, wheat biomass under Cd and Pb combined pollution is smaller than that under single Cd pollution or single Pb pollution. The application of Fe fertilizer increases Cd absorption of various parts of wheat. In the single Cd pollution treatment, with the increase in Fe dosage, Cd concentrations in roots, stems and leaves of wheat will first be increased, then decreased; in Cd and Pb combined pollution treatment, with the increase in Fe, Cd concentrations in roots, stems and leaves of wheat will also be increased. The application of Fe promotes the Pb absorption of wheat. With the increase in Fe dosage, Pb concentrations in roots, stems and leaves of wheat will first be increased, then decreased slightly. Compared with Zn0, Cd concentrations of different parts of wheat after Zn1 and Zn2 treatment increase significantly. In addition, with the increase in Zn dosage, Cd concentrations of different parts of wheat will first increase, then decrease. Regardless of single Pb pollution treatment or Cd and Pb combined pollution treatment, Pb concentrations of different parts of wheat decrease as Zn dosage increases. Under different Fe and Zn levels, and when Cd and Pb coexist, Pb can promote Cd absorption of plant, but Cd inhibits Pb absorption of plant.

    Abstract: The competitive absorption and desorption of cadmium (Cd), lead (Pb) and zinc (Zn) in meadow brown soil from Liaoning province in north-east China was studied in the paper in order to establish the selectivity sequences for the sorption and desorption of these heavy metals in the soil and obtain the absorption and desorption dynamic character of these heavy metals. The results showed that with the increasing of the absorption times, the absorption quantities of Cd, Pb and Zn were increased little by little. The absorption process of Cd, Pb and Zn could be divided into the fast absorption phase and the slow absorption phase. And the fast absorption phases were from the beginning to 60 min, 120 min and 120 min for Cd, Pb and Zn, respectively. The more company metals (i.e. Pb and Zn) existed in the absorption solutions, the less absorption quantities of Cd absorbed by soil. The co-existence of Cd, Pb and Zn had obviously decreased the absorption of Pb by soil. And it was the same situation that Zn absorbed by soil was decreased by the company metals such as Cd, Pb. The company metals had obvious influence on the desorption process of Cd. The existence of Pb and Zn promoted the desorption of Cd. And desorption behavior of Zn was bated by the existence of Pb and Cd. While the company metals Cd and Zn restrained the desorption of Pb. The best equation to describe the absorption and desorption dynamic character of Cd, Pb and Zn was Elovich equation, next was Two–constant equation, and the effect of First-order dynamics equation was not good.

    Abstract: In order to investigate the effects of four heavy metal tolerant microorganisms, Staphylococcus pasteuri (X1), Agrobacterium tumefaciens (X2), Penicillium chrysogenum (Z1) and Paecilomyces lavender (Z2), on heavy metals uptake by the heavy metal tolerance plant-maize and the cadmium hyperaccumulator plant-Beta vulgaris var. cicla L., a pot experiment with sediments was conducted. Through comparing the overall situations of four microorganisms’ role in enhancing maize and Beta vulgaris var. cicla L. to gather cadmium, lead, copper and zinc, plant biomasses, and enrichment characteristics, the combination of bacterium X2, fungus Z2 and these two plants can effectively repair these four heavy metals in sediments.

    Abstract: This study chooses the industrial wasteland after the relocation of a metal processing factory in Shenyang, Liaoning Province of China as the research object. Based on level three soil heavy metal quality standards of Soil Environment Quality Standard (GB15618-1995) in China, the pollution levels of four heavy metals (cadmium, lead, copper and zinc) in survey area are Cd 〉 Cu 〉 Zn 〉 Pb; the Cd pollution is the most serious one, followed by Cu and Zn. The Pb content is low. Average comprehensive pollution index of Cd, Cu, Zn and Pb in soil of the wasteland is 17.33, which belong to Grade V severe pollution. The most polluted point is J-12, followed by J-11 and J-16. The land utilization risk assessment of the wasteland should be strengthened, and appropriate and necessary repair measures should be taken, such as planting accumulative or tolerant plants.
