Removal of Cadmium from Aqueous Solution by Soft Phosphate Rock in Dynamic System

M. Baher Alkaddour, Omar Alabed Allah

Abstract


This research aims to study the effectiveness of Syrian Phosphate Rock (PR) to remove cadmium from aqueous solution under conditions of dynamic system in addition to the impact of the added amount of sediment in the amount of cadmium adsorbed from the solution; cadmium concentration of about 13.4 mg/liter was added to the artificial soil solution. We mixed soft PR with washed sand ratio (0, 2.5 and 5 g natural sediment/100 g sand) and placed about 100 g of the mix in a tube of polyethylene. Then, we washed the mix column by artificial soil solution. The results showed that the amount of cadmium adsorbed from the solution, removal efficiency, breakthrough point, the column exhaustion point, the total balance capacity of soil column, breakthrough capacity and the column efficiency or the degree of saturation increased when the amount of soft PR added increased. Thus, we can increase the amount of wastewater containing cadmium, which are used to irrigate some crops with increasing the amount of of soft PR added to soils irrigated by these waters. So, we can increase the amount of wastewater containing cadmium, which is used to irrigate some crops, the lower concentration of cadmium into.
