Adsorption of Co(II) from aqueous solutions by water treatment residuals

Recent efforts have increasingly focused on the development of low-cost adsorbents for Co(II) removal. In this work, the novel reuse of water treatment residuals (WTRs), a nonhazardous ubiquitous byproduct, as an adsorbent for Co(II) was investigated. This study was focused on the factors influencing Co(II) immobilization by WTR. Results showed that WTR as an adsorbent is suitable for removing Co(II) from aqueous solutions.76
