A Modified Method to Calculate Critical Coagulation Concentration Based on DLVO Theory

A Modified Method to Calculate Critical Coagulation Concentration Based on DLVO Theory

The critical coagulation concentration (CCC) is defined as the minimum concentration of counterions to induce coagulation of colloidal particles. A modified calculation method was proposed to calculate CCC. Comparing the modified calculation method of CCC with the traditional calculation method, the...
