Thin films of ZnO, Cu-doped Cu2O and binary Cu2O/Cu-doped ZnO p-n heterojunction thin film were prepared tested for their heterogeneous photocatalytic activity in the removal three selected organic dyes: methylene blue (MB), orange (MO) Congo red (CR). The experiments carried out under UV light natural sunlight. synthesis photocatalysts was by an electrochemical deposition method resulting char...

Now-a-days nanotechnology is one of the booming fields for researchers. With increase in industrialization mainly textile, paper, medicine, plastic industry, there an concentration organic dyes as pollutant. Release harmful water bodies has become a serious issue, most are carcinogenic and mutagenic nature causes various diseases. Therefore, requirement to find out new approaches efficient trea...

A highly stable graphene-like metal-organic framework (BUC-17) was prepared and used as an adsorbent to carry out the adsorption of anionic dyes from simulated wastewater, which exhibited excellent adsorption performance, particularly towards Congo red (CR) up to 4923.7 mg g-1 at room temperature. It was used to fix a SPE column to conduct rapid separation of anionic dyes from an organic dye ma...

Biochemical degradation test of food coal-tar dyes using sludge was studied in order to evaluate their safety. It was found that some dyes were little decomposed under aerobic condition but four azo dyes were readily decomposed under anaerobic condition. These were Food Yellow No. 4, No. 5, and Food Red No. 2, No. 102. Decomposed products of these four azo dyes by sludge under anaerobic conditi...
