1. A precipitation mechanism was convinced for Cd(II) adsorption. The O1s peak was deconvoluted into three peaks, and the molar ratio of -COO -groups at 533.15 eV were increased by 7.39% and 6.59% for As(III) and Cd(II) adsorption, respectively (Figure 7 a, b, and d), implying ion exchange process occurred during As(III) and Cd(II) adsorption;; Cr;The significantly increased intensity of the sulfhydryl peak at 163.7 eV for As(III) and Pb(II) adsorption indicates a strong binding between sulfhydryl and As(III)/Pb(II) (Figure 7 b and e,2015
