Removal of Reactive Black 5 Azo Dye from Aqueous Solutions by a Combination of Reduction and Natural Adsorbents Processes

Removal of Reactive Black 5 dye from Aqueous Solutions by Adsorption onto Activated Carbon of Grape Seed

Background and purpose: The control of environmental pollution especially the pollution of water resources is one of the main challenges of researchers throughout the world. So, this study aimed to investigate the efficiency of reactive black 5 dye removal from aqueous solutions by adsorption onto activated carbon of grape seed. Materials and Methods: At first, the grape seed adsorbents were p...

Decomposition of a Di Azo Dye in aqueous solutions by

This study examined the photolytic degradation of C.I. Acid Red 73 AR73 diazo dye, in aqueous solution by combined UV, hydrogen peroxide and KMnO4. A continuous circulated photoreactor equipped with a low pressure mercury lamp 15 W, emission 253.7 nm was used. In the first step, potassium permanganate was used for decolourisation of AR73 dye solution. The effect of the key operating variables s...

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

Removal of hazardous reactive blue19 dye from aqueous solutions by agricultural waste

Low-cost grapefruit peel (Agricultural Waste) was used for removal of reactive blue19 dye fromaqueous solutions. The process was studied as a function of contact time, initial dye concentration andpH. Adsorption process was attained to the equilibrium within 45 min for initial dye concentrations of 50,75, and 100 mg L-1. An acidic medium was the optimum condition for adsorption of dye at roomte...

Removal of textile dye from aqueous solutions by nanofiltration process

The feasibility of employing nanofiltration (NF) in the decolorization of ionic (direct blue 86) and nonionic (disperse blue 56) dye aqueous solutions was investigated. The effects of feed concentration (60- 180 mg/l), pressure (0.5- 1.1 MPa) and pH (6- 10) were studied. Experiments were performed in a laboratory- scale set up by using a TFC commercial spiral wound polyamide nanofilter. The res...
