Studies on the removal of copper ions from

2019-12-3  The experimental result shows that the percentage removal of copper was highest at the following optimized conditions: pH 7.0, stirring time 60 min and biosorbent dosage of 1.0 g and at 125 RPM speed. The studies indicate that A. indica is considered to be a promising type of biomass for the removal of copper ions from aqueous solutions.
