4. Description Abstract

The purpose of this work is to synthesize and modify by epichlorohydrin (ECH) a natural polyelectrolyte chitosan. Its purpose is also the treatment of liquid effluents from hot-dip galvanizing, where the treatment is based on the coagulation/flocculation process. The synthesized and modified polymer was characterized by Fourier Transform Infrared Spectroscopy and Polarizing Optical Microscope. The result obtained concerning the microstructural characterization confirms the structure of chitosan(S) and chitosan-epichlorohydrin.

The treatment of effluent samples by means of chitosan(S) and chitosan-ECH allowed us to obtain interesting values concerning the physicochemical parameters.

These results obtained are translated into minimum values of the physical-chemical parameters. Indeed, treatment with lime/chitosan-ECH, could remove of 97.30% suspended solids; 99.20% of chemical oxygen demand; 98.45% of biochemical oxygen demand; 88.76% zinc ion and 83.68% copper ion. However treatment with lime/chitosan(S) we obtained only a removal of 97% suspended solids; 99% of chemical oxygen demand; 98.31% of biochemical oxygen demand; 78.88% of zinc ion and 72.64% of copper ion.
