MATHEMATICAL KINETIC AND THERMODYNAMIC STUDY OF ADSORPTION OF COPPER II BY ALKALINE SOIL USING BATCH METHOD

Contamination of soil with heavy metal directly depends upon the adsorption capacity of metal either onto the soil or leaching from soil which tends to have long time or instantaneous effects to soil qualities and related cofactors. In this way the aim of this work was to study the adsorption of copper (II) on to the soil in different depth as [SS]0-15 and [SS]15-30. Rate of adsorption of ion from 0 minute to in?nite were observed and found nearest to ?rst order reaction after calculation. The calculated values of data gave the gibbs free energy negative which indicates spontaneity of ion adsorption process in soil sample from different depth of selected area.
