“…Cobalt ions are present in the effluents of nuclear reactors, medical, food and other industries.It causes problems of nosohemia, alopecia,carcinogenicity, etc [1][2]. Several papers showed natural silicate minerals were applied to remove heavy metal ions from aqueous solution [3][4].We learned from these studies that the low-cost magnesium silicates would be an ideal and potential candidate as adsorbents in removing heavy metal ions from aqueous solution [5][6][7]. But in practical application, magnesium silicate powder is difficult to operate for its fluidity and poor permeability, adsorption recovery and replacement are need to filter and other post-treatment, likely to cause the problem of mesh plug and magnesium silicate erosion.…”

The groundwater contaminated with cobalt is attracted more and more concern. In this study, molded magnesium silicate (MMS) was successfully prepared and the physico-chemical properties were determined by N2 adsorption/desorption isotherm and Scanning Electron Microscopy (SEM). Surface area and the average pore size were 333.19 m2·g-1 and 4.442 nm. Adsorption experiments of removal of cobalt ions was investigated as the function of initial concentration, adsorbent dose and adsorption time. Adsorption process was rapid and adsorption equilibriums were achieved soon.
