Elimination of Mercaptobenzothiazole from Cefixim Waste by Zeolite

Wastewaters of chemical and pharmaceutical industries because of their high COD (Chemical Oxygen Demand) levels can contaminate environment and central sewage treatment basins. Organic solvents introducing to sewage system and impurities from drug synthesis processes are within the most important contaminants. Mercaptobenzothiazole (MBT) which is a by-product in cefixim synthesis, directly increase COD levels of the wastewater. The present article concerns reduction and elimination of this contaminant by an activated natural zeolite, clinoptilolite. According to our studies, clinoptilolite can decrease more MBT and consequently more COD from cefixim wastewater in the same conditions as compared with activated carbon.
