The cation exchange capacity (CEC) of a soil is a measure of the quantity of negatively charged sites on soil surfaces that can retain positively charged ions (cations) such as calcium (Ca 2+), magnesium (Mg), and potassium (K+), by electrostatic forces. Cations retainedSoil Cation Exchange Capacity. Donald S. Ross and Quirine Ketterings . The cation exchange capacity (CEC) of a soil is a measure of the quantity of negatively charged sites on soil surfaces that can retain positively charged ions (cations) such as calcium (Ca 2+), magnesium (Mg), and potassium (K+), by electrostatic forces. Cations retainedThe measurement of the ion-exchange capacity (IEC, mEq/g) was carried out according to the State Standard GOST 20255.1-89 and GOST 20255.2-89. A sample of the dry cation exchange membrane in proton form was weighed and placed in a dry conical flask with an NaOH solution. The flask was sealed with a stopper and stirred for several hours.
