The adsorption of Co(lI) by well characterized China clay in the pH range (3.0 - 6.5) at various temperatures followed the Langmuir isotherms. Co(IT) removal is favoured by low concentration. low temperature, and low pH. The high adsorption capacity at low pH is attributed to the content of silica in China clay.
