Optimization of process variables for a biosorption of nickel(II) using response surface method

The biosorption of nickel(II) was studied by using crab shell particles of diameter (dp=0.012 mm) under different initial concentrations of nickel(II) in solution (0.01-5.0 g/l), temperature (20-40 oC), pH (2-6.5), and biosorbent dosages (0.5-10 g/l). The maximum removal of nickel(II) occurred at...
