UTILIZATION OF SOME BIODEGRADABLE MATERIALS FOR WATER TREATMENT IN SOME STEAM POWER PLANTS

Abstract

This work deals with the synthesis of soluble cationic alginate and cationic chitosan having Quaternary amino groups by the reaction of both alginate and chitosan with 3-chloro-2-hydroxypropyl triethylammonium chloride (CTAC) . The produced cationized chitosan and alginate were characterized by FT-IR, Thermogravimetric analysis TGA, and elemental analyse (C,H,N,S) . CC and CA were prepared in the nanoscale and characterized by transmission electron microscopy (TEM). The adsorption efficiency of (CC) for metal ions in water such as Fe3+, Cu2+, Ni2+ , and The adsorption efficiency of (CA) for metal ions as (Fe3+, Cu2+, Cd2+, Ni2+, Co2+, Mn2+, and Zn2+) were determined using atomic absorption spectrometry (AAS) . A field study was also performed on two water chitosan, samples obtained from West Cairo Zone using each of CC , CA alone or mixed with alum in the different proportions . The efficiencies towards the removal of turbidity and some heavy metal ions of some industrial water in power plants were compared .
