Direct Blue 71 Removal from Aqueous Solutions by Adsorption on Pistachio Hull Waste: Equilibrium, Kinetic and Thermodynamic Studies
Background and Purpose: Azo dyes including Direct Blue 71 (DB71) are toxic, mutagenic and carcinogenic contaminants in effluents of industries. This study aimed to investigate the adsorption of DB71 from aqueous solution onto pistachio hull waste (PHW) as a low-cost adsorbent. Materials and Methods: A series of experiments were performed via batch adsorption technique to examine the effect o...
متن کاملOptimization, Equilibrium and Kinetic Studies of Basic Red 2 Removal onto Waste Gossypium hirsutum Seeds
Cationic dye - basic red 2 (BR2) was removed from aqueous solutions by sulfuric acid activated waste Gossypium hirsutum seeds (WGSAB). The main and interactive effects of five process variables such as, adsorbent dose (1.25 – 5 g/L), initial dye concentration (100–300 mg/L), contact time (1–3 h), pH (2 – 12) and temperature (20 – 400C) were investigated via response su...
متن کاملMalachite green dye, removal from waste water by adsorption
The organic dyes directly pollute the soil, water, plants and all living systems in the environment. In the present investigation, adsorption of brilliant green dye on silica from aqueous solution was studied. The dye adsorption mechanism was studied on the basic surface of silica. The adsorption parameters were optimized to maximum adsorption. The adsorption mechanism of brilliant green on sil...
متن کاملRemoval of acid red 88 from wastewater by adsorption on agrobased waste material. A case study of Iranian golden Sesamum indicum hull
Background: Colors are very useful in different industries such as textile and leather but when they enter water, can cause many biological and environmental problems. In the present research, a waste agricultural material which is freely available is employed to analyze its efficiency for removing acid dye from contaminated wastewaters. Methods: In this study, batch adsorption experiments wer...
متن کاملRemoval 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...
