Abstract
ABSTRACT: It was found in this research that the mineral waters contain high concentrations
of TDS which was confirmed by high values of their conductivities which were directly
proportional to their TDS. The levels of TDS in Found waters were not controlled in time of
preparation of these waters. The adsorption of Berlent Green dye on Bentonite Clay surface
decreased with increasing temperature which was confirmed by negative values of enthalpies and
free energies in addition to negative valves of entropies which rendered the system most
regulation. The adsorption follows Frendlich isotherm and the adsorption increased with
decreasing pH which reached its maximum value at pH=1.There fore, these waters should be
defected from time to insure their suitability for drinking and their contents within the water
Health Organization specifications and using(U.V-visible) Instrument, (pH-meter) for
measurements.
