Title

ONE STEP IN-SITU FORMED MAGNETIC CHITOSAN NANOPARTICLES AS AN EFFICIENT SORBENT FOR REMOVAL OF MERCURY IONS FROM PETROCHEMICAL WASTE WATER: BATCH AND COLUMN STUDY

Pages

Abstract

 Background: In the recent years, MERCURY contamination has attracted great deal of attention due to its serious environmental threat.Objectives: The main goal of this study was application of one-step synthesized magnetic (magnetite) CHITOSAN nanoparticles (MCNs) in the REMOVAL of MERCURY ions from PETROCHEMICAL WASTE WATER.Materials and Methods: This study was performed in batch and column modes. Effects of various parameters such as pH, adsorbent dose, contact time, temperature and agitation speed for the REMOVAL of MERCURY ions by MCNs investigated in batch mode. Afterwards, optimum conditions were exploited in column mode. Different kinetic models were also studied.Results: An effective Hg (II) REMOVAL (99.8%) was obtained at pH 6, with 50 mg of MCNs for an initial concentration of this ion in PETROCHEMICAL WASTE WATER (5.63 mg L-1) and 10 minutes agitation of the solution. The adsorption kinetic data was well fitted to the pseudo-second-order model.Conclusions: Experimental results showed that MCNs is an excellent sorbent for REMOVAL of MERCURY ions from PETROCHEMICAL WASTE WATER. In addition, highly complex matrix of this waste does not affect the adsorption capability of MCNs.
