USE OF NATURAL ZEOLITES FOR CATALYTIC OXIDATIVE DEGRADATION OF ORGANIC DYES IN THE AQUEOUS PHASE
The article studied the catalytic degradation of azorubine and methylene blue in an aqueous solution in the presence of natural zeolites: chabazite and clinoptilolite as catalysts. It has been found that clinoptilolite, which has a lower specific surface area than chabazite, exhibits a higher degree of dye conversion in catalytic oxidative degradation. The degree of purification of clinoptilolite and chabazite from azorubine was 1 and 0,89, respectively, from methylene blue was 0,94 and 0,92, respectively.
