The characterization and adsorption studies of Cd 2＋ on FeS were performed. Adsorption of Cd 2＋ from aqueous solutions on synthetic iron sulphide (FeS) was investigated as a function of pH (5-7) and temperature (303-323 K). It was found that the iron sulphide (FeS) had adsorptive properties comparable with those of other adsorbents reported in the literature. The sorption of Cd 2＋ was observed to increase with the increase in pH but not strongly sensitive to temperature. The adsorption data fitted both the Kurbatov and Langmuir adsorption models. In addition, ∆G values were calculated from the values of the binding constant, which showed that the cadmium adsorption process was spontaneous in nature.
