Optimization studies on Biosorption of Copper (II) by Crab Shell Using Response Surface Methodology(RSM)

In the present work, crab shell was used as the biosorbent to remove copper from aqueous solution. Batch experiments were performed at different initial copper concentration of copper solutions (1-40 g/l), initial pH (2-9), temperature (20-400C), and biosorbent dosages (2-10 g/l). The maximum rem...
