MEASUREMENTS OF MINERAL WATERS POLLUTION IN ADSORPTION THERMODYNAMIC STUDY 0F BERLENT GREEN DYE ON SURFACE BENTONITE CLAY

Abstract

ABSTRACT: It was found in this research that the mineral waters contain high concentrationsof TDS which was confirmed by high values of their conductivities which were directlyproportional to their TDS. The levels of TDS in Found waters were not controlled in time ofpreparation of these waters. The adsorption of Berlent Green dye on Bentonite Clay surfacedecreased with increasing temperature which was confirmed by negative values of enthalpies andfree energies in addition to negative valves of entropies which rendered the system mostregulation. The adsorption follows Frendlich isotherm and the adsorption increased withdecreasing pH which reached its maximum value at pH=1.There fore, these waters should bedefected from time to insure their suitability for drinking and their contents within the waterHealth Organization specifications and using(U.V-visible) Instrument, (pH-meter) formeasurements.
