Apparent and partial specific adsorption of 1,10-phenanthroline on mixtures of Ca-montmorillonite, activated carbon, and silica gel

A model for adsorption of 1,10-phenanthroline (OP) on a ternary mixture is presented, to determine the adsorption in the main component of the mixture, based on the thermodynamic concept of the apparent and partial quantities in combination with an equation representing total adsorption of the other two adsorbents as a function of the weight fraction of one of them and introducing the concept of mean total adsorption.
