-bearing laterite coexisting with high concentration of magnesium and iron ions. The effects of operational parameters on the valid adsorption quantity and efficiency of resin were studied, such as pH...% and 58.0 g/kg, respectively, while the resin becomes saturated under the conditions of Ni2+ initial mass concentration of 2.5 g/L, pH of 4.5, and flow velocity of 1.0 L/min. Moreover, the valid......
and the concentration of metals was determined by atomic adsorption spectrometry. The formed precipitates (Ni-PSt/MA) were isolated from the solution by centrifugation, then washed with water to remove Ni2...
