Abstract:
A novel sodium lignosulphonate (SLS)-polyvinyl alcohol (PVA) spherical macroporous bioadsorbent (SLSP) was synthesized by reversed phase suspension polymerization. Comparing with powdery and high water solubility SLS, this new spherical bioadsorbent exhibited relative stability under static force. SEM and FTIR proved the cross-linking of SLS and PVA. TG curves of SLS and SLSP indicated that the thermal property of SLS had been improved by cross-linking modification. Meanwhile, comprehensive adsorption study of Pb (II) on this bioadsorbent was conducted regarding the effects of time, initial PH and initial Pb (II) concentration. 90% of Pb (II) from aqueous solution could be removed by 0.4g of the adsorbent at 25°C for less than 3h. The adsorption process was determined to be consistent with the Langmuir isotherm.
