Exploiting the performance of hyper-cross-linked polystyrene for removal of multi-component heavy metal ions from wastewaters

In this research, Hyper-cross-linked polystyrene was used for simultaneous removal of nickel and lead ions. The necessary number of experiments and optimum values of each factor were determined using response surface methodology (RSM). The optimum value of temperature, nickel, and lead concentrations, and pH was obtained 60 ℃, 50.715 mg/L, 80 mg/L, and 7 respectively, for Ni(II) adsorption in which the nickel uptake and selectivity were...
