Abstract

Industrial wastewaters are deposed into the River Nile without any treatment. High concentrations of some heavy metals i-e Ni⁺², Cu⁺², Zn⁺², CO⁺²and Cd⁺², promate the growth of gelatinous masses and hence cause industrial and agriculture problems. Polluted water may cause many health problems such as liver and kidney diseases. The aim of the present study is an attempt to removal heavy metals in industrial wastewater. Also, evaluation of some agricultural wastes such as orange peels, banana peels and leaves of date trees as biosorbent to remove the heavy metals which presenting from wastewater such as nickel (Ni⁺²), copper (Cu⁺²), zinc (Zn⁺²), lead (pb⁺²), cobalt (CO⁺²) and cadmium (Cd⁺²) by using prepared active carbons from the above-mentioned materials of different agricultural wastes in batch adsorption process. Proximate, chemical components of lignocellulosic wastes under investigation were determined. Also, physical and chemical preparation of wastewater and the produced active carbons from different agro-wastes were evaluated. On the other hand, the activated carbons from different agro-wastes were used as biosorbents for removal of some above-mentioned heavy metals before deposing in wastewater.
