摘要：

A method for the rapid determination of CEC values in days using an ethylenediamine complex of Cu was tested with different clays. The single-step procedure is fast and does not require sophisticated apparatus. The exchange with most cations-and even with those of heavy metals-is irreversible and can be carried out over a range of pH values. The results, which can be obtained using a wide variety of analytical techniques, are generally in good agreement with those given by the classical Kjeldahl method.
