Determination of exchange capacity can be achieved  the static or dynamic method. In static method  cation exchanger in acid form is titrated with caustic solution. In the dynamic method, a column filled with cation exchange resin (m-your weight activated carbon) , and the electrolyte solution is passed record swallowing dependence ion concentration(c) in the eluate of the volume of solution passed (Vpas.).

CEC = Vpas.c/m

Thanks Pr Yuri,

do you have some paper about that you showed me?

This is a simple laboratory work for my students from

Лабораторные работы и задачи по коллоидной химии. М.: "Химия", 1986.-216 с.
