摘要

A method is described for highly efficient adsorptive removal of lead with a maximum metal capacity value of 1.300 mmol g~(-1) by using physically immobilized [Bmini~*Tf2N~_] on the surface of nano-silica-amine sorbent. Lead sorption was found to be highly dependent and controlled by several experimental factors. The effect of sorbent dose played a significant role by yielding the maximum lead adsorption capacity when 100 mg sorbent was used. The effect of lead concentration was examined by various adsorption isotherms. The potential applications for removal of Pb(II) were studied and the percentage recovery values were 99.0-100.0 ± 2.0-5.0%.
