Extract

The most widely used procedure for determining the cation exhange capacity (CEC) of a clay involves ammonium ion exchange, followed by Kjeldahl measurement of the ammonia released on treatment with alkali (Grimshaw, 1971; Mackenzie, 1951). The method is experimentally quite difficult, prone to error and time consuming.
