Many convenient materials and tools have been supplied by the chemical industry. Accompanying with such phenomena, pollutants and industrial waste has been accumulated in the environment. Clay minerals play important roles in environmental studies. Interactions between metal ions in aqueous solution and clays were discussed. Affinity of various clay minerals for divalent metal ions in aqueous solution was different and the sorption ability of clay minerals for metal ions did not exceed their CEC values. Sorption of non polar organic compounds in aqueous solution with clays was promoted by the intercalation of cation surfactants in the interlayer of the clays. Sepiolite has been used as a useful deodorizer because the smelling materials such as NH_3, alkylamine and thiophen are strongly adsorbed in the intracrystalline channels of sepiolite.
