Degradation of Azo Dye Reactive Black 5 and Acid Orange 7 by Fenton-Like Mechanism

Electrode Composition of Reactive Black 5 Dye in Aqueous Solution

High oxygen evolution overpotential and inexpensive Ti/Co3O4/PbO2/(SnO2+Sb2O3) and (Ti/(SnO2+Sb2O3) electrodes were investigated in this work. These electrodes were prepared and used as anodes for removal of Reactive Black 5 (RB5) dye in aqueous solution. In some local cases in Palestine, wastewater color was found to be the only problem in meeting local effluent standards. This investigation r...

Adsorption Kinetics and Equilibrium Studies of Reactive Red 198 Dye by Cuttlefish Bone Powder

In this research, the removal of Reactive Red 198 dye (RR-198) by Cuttlefish bone powder was investigated. The adsorbent was prepared in laboratory conditions and ground by ASTM standard sieves (60-100 mesh). The progress of the process is monitored spectrophotometrically by measuring the absorbance of dye at 518 nm wavelength. In addition, the effects of process parameter...
