    • Application of modified clay for removal of phenol and

      Simultaneous adsorption of phenol and phosphate(V) ions on the surfactant modified clay from the binary mixture was studied and compared with the single phenol or phosphate(V) sorption. The maximum adsorption capacity of hexadecyltrimethylammoniumbentonite was 18.8 mg/g for phenol and 38.5 mg/g for phosphate(V) at simultaneous adsorption of both of them.
