COMPARISON OF DEGRADATION CAPACITY OF OXIDATION AND PHOTOOXIDATION OF SULFIDE CATALYZED BY Zn(II) TETRASULFOPHTHALOCYANINE VÀ Co(II) TETRASULFOPHTHALOCYANINE

Abstract

The oxidation and photooxidation of sulfide catalyzed by soluble phthalocynines were carried out. The results showed that both Zinc(II) Tetrasulfophthalocyanine (ZnTSPc) and Cobalt(II) Tetrasulfophthalocyanine (COTSPC) have catalytic activities in the oxidation of Sulfide. The degradation yiel minute under the light visible irradiation and in the dark were 96,61% and 71,11% respectively. Whereas, in case of CoTSPc during 40 minute, these were 98,10% and 96,30%, respectively. ZnTSPc demonstrates the photoactive property and catalyses the reaction via type II (singlet oxygen mechanism). COTSPc has not the photoactive property and catalyses the reaction via type I (electron transfer mechanism).
