Heterogeneous Sulfidation Characteristic of Copper, Zinc and Nickel in Simulated Plating Wastewater Using Calcium Sulfide

Selective Sulfidation of Copper, Zinc and Nickelin Plating Wastewater using Calcium Sulfide

The present work is concerned with sulfidation of Cu, Zn and Ni containing plating wastewater with CaS. The sulfidation experiments were carried out at a room temperature by adding solid CaS to simulated metal solution containing either single-metal of Ni, Zn and Cu, or Ni-Zn-Cu mixture. At first, the experiments were conducted without pH adjustment and it was found that the complete sulfidatio...

Removal of Copper and Zinc from Wastewater Using Chitosan

Removal of nickel, copper, zinc and chromium from synthetic and industrial wastewater by electrocoagulation

In this work, the performance of electrocoagulation with aluminum electrodes for simultaneous removal of nickel, copper, zinc and chromium from synthetic aqueous aliquot solutions and actual electroplating wastewater was studied. Parameters affecting the electrocoagulation process, such as initial pH, current density, initial metal ion concentration, COD and contact time were investigated. Best...

Photodegradation of HMX and RDX in the Presence of Nanocatalyst of Zinc Sulfide Doped with Copper

Nanoparticles of zinc sulfide as undoped and doped with copper were used as photocatalyst in the photodegradation of HMX (octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine) and RDX (hexahydro-1,3,5-trinitro-1,3,5-triazine) as nitramine explosives under UV and Vis irradiations. Photoreactivity of doped zinc sulfide was varied with dopant, mole fraction of dopant to zinc ion, pH of solut...
