Optimization of Ni2+ adsorption on 13X zeolite using box-behnken design
Shoeib Jafari and Farideh Bandarchian

    In this study, the elimination of Ni2+ using 13X sorbent due to an electrostatic interaction was reported. The significant factors including pH, time and 13X sorbent amount were investigated using Box-Behnken design (BBD). In the optimum experimental conditions, the linear rang and limit of detection of the proposed method were 0.1-20 and 0.102 mg L-1, respectively. The precision as RSD% was 1.3% for concentration of 2 mg L-1. Concerning the excellent recoveries in a short time with highly efficient sample clean-up and removal, this method may be a very powerful and innovative future sample removal technique. To the best of our knowledge, this is the first report on using BBD for optimizing the parameters affected the removal of Ni2+ by 13X zeolite sorbent.
