Abstract:
MgO doped PbFe 2 O 4 (MgO‐PbFe 2 O 4 ) is synthesized by co‐precipitation followed by ultrasonication method. The study was carried out for the effective adsorption of hexamethyl pararosaniline chloride dye (HPCD) on MgO‐PbFe 2 O 4 from the industrial effluent. The experimental and theoretical physical models are used to explain the mechanism of the dye adsorption process. The simulation of dye adsorption assuming interaction HPCD + MgO‐PbFe 2 O 4 is proposed from two types (a) adsorption of dye on MgO‐PbFe 2 O 4 surface, and (b) the trapping of the HPCD dye in the pores and cavities present in the MgO‐PbFe 2 O 4 surface. A theoretical measurement displays the parameter n pattern as a solution temperature function was n = 0.373, 0.371, and 0.321 at 298, 308, and 318 K, respectively (i.e., all values were below 1). Thus, during interactions between HPCD and MgO‐PbFe 2 O 4 active sites, horizontal molecular positioning and multi‐locking mechanisms were involved. The kinetic model shows that the HPCD adsorptions on MgO‐PbFe 2 O 4 follow the reaction's pseudo‐first‐order. Langmuir isotherm modeling best fitted and describes the HPCD‐MgO‐PbFe 2 O 4 adsorption system for HPCD dye in 40 min with Q max at 333.33 (mg L –1 ). The reused study and application in the removal of dye from the industrial effluent make MgO‐PbFe 2 O 4 effective material for pollution control.
