Sphalerite is a sulfide zinc mineral, which also contains supporting metals such as iron, copper and lead. In this work, we dealt with the extraction of iron from sphalerite in a new oxidation system. Manganese dioxide was used as the primary oxidant, and KI was used as a secondary oxidizing agent with the aim of creating an I2/I- oxidation cycle i...

Water pollution by organic matters are in increase. Photocatalytic degradation of various pollutants presented in environment has promising future. Different materials have been applied in previous scientific works, while TiO2 based materials posse’s great physico-chemical characteristics. Therefore, researchers are constantly developing vari...
