I recommend you article:

k.p. Kitsopoulos, 1999, cation-exchange capacity (cec) of zeolitic volcaniclastic materials: applicability of the ammonium acetate

saturation (amas) method, clays and clay minerals, 47 (6), 688-696.

Nagabushan Suma

For surface area estimation BET is the best method.CEC can be carried out by using 1N BaCl2 at pH 7 followed by displacement of the exchanged barium with 0.1 N HCl. The barium can be determined by gravimetric method as barium sulphate
