Abstract
In this work the possibility of removing lead metal ion with Fe3O4 magnetic nano particles from aquent samples and measuring the remained solution was investigated. Chitoson was used for this purpose. Chitosan is a hyphophilic and cationic polymer that obtained from removing acetil citin in basic solutions and use as an absorptive to removing heavy metals. The experiments of this investigate was carried out in discrete system and room temperature. pH, commence concentration of metal, time were optimized by experimental design. The optimum condition for pH, the amount of sorbent, commence concentration of metal and time were 4.14, 0.06 g, 60 mg L-1 and 66 min respectively. Recover of sorbent by EDTA and multi usages are important merit of this sorbent.
