Abstract

 CONDUCTING ORGANIC POLYMERS SUCH AS UREA FORMALDEHYDE HAVE ATTRACTED, ON THEIR OWN, A GREAT INTEREST, THANKS TO THEIR EXTRAORDINARY PROPERTIES AND LATENT APPLICATIONS. THESE MATERIALS ARE FORMED BY OXIDATIVE POLYMERIZATION OF THE RELEVANT MONOMERS [1].POLYOXOMETALATS (POMS) AS A UNIQUE CLASS OF VERSATILE METALOXYGEN CLUSTER COMPLEXES HAVE BEEN ATTRACTING EXTENSIVE INTEREST DUE TO NOT ONLY THEIR AESTHETICALLY TOPOLOGICAL PROPERTIES BUT ALSO THEIR POTENTIAL APPLICATIONS IN CATALYSIS, PHOTOCHEMISTRY [2]. THE PHOTO CATALYTIC ACTIVITY OF THE SUPPORTED POLYPHOSPHOTUNGSTATE WAS TESTED VIA DEGRADATION OF DIFFERENT DYES IN AQUEOUS SOLUTIONS [3-5]. IN THIS METHOD THE RATE OF COLOR DEGRADATION OF ENVIRONMENTAL CONTAMINANT INCLUDING: METHYL BLUE AND METHYL ORANGE AND FOSHIN IN PH AND THE OPTIMAL CONCENTRATION AND DURATION OF EXPOSURE WAS EXAMINED IN PHOTOCHEMICAL. THIS RESEARCH RESULTED IN OPTIMAL CONDITIONS THE DESTRUCTION CAUSED BY THE LIGHT OF TWO COLORS METHYL BLUE AND METHYL ORANGE 99% AND FUSHIN 91%.
