Industrial wastewater containing heavy metal ions can cover the full pH range according to the manufacturing process. Alk. wastewater treatment is still a great challenge because Cr6+ therein has a more neg. reduction potential (Cr2O27- + 14H+ + 6e- = 2Cr3+ + 7H2O (ECr6+Cr2O72-Cr3+) = Eθ – ((RT)/(nF))ln[OH]-) than in acid solution, in which it can be easily reduced by numerous reagents. In this study, weakly alk. Cr6+ solution has been used to simulate weakly alk. industrial wastewater, and a reagent capable of excellent reduction efficiency therein has been developed. A series of band-gap-energy-adjustable NiS-ZnxCd1-xS composites has been synthesized by a one-pot hydrothermal method. A more neg. conduction band position for ZnxCd1-xS has been achieved by doping and changing the amount of Zn2+ ions to ensure a superior photoreduction ability. All modified samples show excellent photocatalytic efficiency. For example, the reduction efficiency of 10%NiS-Zn0.25Cd0.75S sample is threefold higher than that of Zn0.25Cd0.75S and sixfold higher than that of CdS when deployed at a catalytic level for 30 min. Multiple characterization methods have been applied, and the results show that the improved efficiency can be ascribed to intimate contact between Zn0.25Cd0.75S and NiS. Photoluminescence (PL) and photocurrent measurements and electrochem. impedance spectroscopy (EIS) further elucidate the catalytic mechanism and imply an enhanced charge-carrier separation efficiency between Zn0.25Cd0.75S and NiS. The experimental process involved the reaction of 1-Iodopyrrolidine-2,5-dione(cas: 516-12-1Product Details of 516-12-1)
1-Iodopyrrolidine-2,5-dione(cas: 516-12-1) is used in the preparation of vinyl sulfones from olefins and benzenesulfinic acid. It acts as a source for I+ and involved in Hunsdiecker reactions for the conversion of cinnamic acids, and propiolic acids to the corresponding alfa-halostyrenes and 1-halo-1-alkynes respectively.
