BIOCHEMICAL STUDIES ON SOME AQUATIC ORGANISMS FOR BIOREMEDIATION OF ORGANIC AND INORGANIC WATER CONTAMINANTS By
WALAA SALAH EL DIN ABD EL MONSEF ALI;
Abstract
The aim of current study was to evaluate the ability of different untreated aquatic
organisms and chemically-modified by crosslinking with epichlorohydrin (EC1, EC2 and
EC3), or oxidizing by potassium permanganate (PC), or treated with sodium hydroxide to
remove soluble lead and cadmium from water solution. Also, to determine the ability of
these organisms for removal/degradation of glyophosate as organic contaminants (water
soluble herbicide). The aquatic organisms (micro, macro algae and Eichhornia crassipes)
were obtained from Botany and Microbiology Department, Faculty of Science, Cairo
University, Abu Qir beach (Alexandria) and El-Zomor canal (Giza) respectively. a) For
bioremoval of heavy metals, the viable aquatic organisms were exposed to lead
(Pb(NO3)2) or cadmium (CdCl2) at a concentration of 10 mg/L for a time period of 240
min. All measurements were done in triplicates and performed in accordance with standard
methods. These data were used to calculate the removal efficiency with respect to time,
and to provide the necessary empirical constants to model the removal behavior.
