Role of activated carbon from natural adsorbent for removal of textile dyes: effect of pH, kinetic and adsorbent mass
In the present work, we have investigated the sorption efficiency of the treated activated carbon from walnut shell(ACW) towards Direct Red 81 (DR81) and Direct Blue 71 (DB71) for the removal from aqueous solution. Thesorption study of ACW at the solid-liquid interface was investigated using kinetic, sorption isotherms, pH effectand amount of adsorbent. Experimental data were analyzed by Langmu...
متن کاملAdsorption of arsenic(III) and arsenic(V) from groundwater using natural siderite as the adsorbent.
Batch and column tests were performed utilizing natural siderite to remove As(V) and As(III) from water. One hundred milligrams of siderite was reacted at room temperature for up to 8 days with 50 mL of 1000 microg/L As(V) or As(III) in 0.01 M NaCl. Arsenic concentration decreased exponentially with time, and pseudoequilibrium was attained in 3 days. The estimated adsorption capacities were 520...
متن کاملDefluoridation Of Water by Moringa Oleifera- A Natural Adsorbent
The water available for daily consumption may be contaminated by natural sources or by industrial effluents. One such a contaminant is fluoride. Exposure to fluoride in drinking water has a number of adverse effects on human health. One of the naturally available alternatives for defluoridation of water is Moringa Oleifera. Using colourimetric method, tests were conducted to get optimal values ...
متن کاملAdsorptive Removal of Dye from Industrial Effluents Using Natural Iraqi Palygorskite Clay as Low-cost Adsorbent
Palygorskite clay has been investigated as low cost and ecofriendly adsorbent for the removal Basic Red 2(BR-2) from aqueous solution. Batch adsorption studies are carried out by observing effect of amount of adsorbent dose, contact time, pH, initial concentration of ( BR-2) and particle size of adsorbent on the adsorption capacity of the adsorbent were studied. Adsorption data fits the Langmui...
متن کاملAdsorptive removal of methylene blue using the natural adsorbent- Vitex negundo Stem
The mechanism of Methylene Blue adsorption on acid activated carbon Vitex Negundo Stem (AAVNS) has been studied through batch experiments. Generally, dyes are organic compounds used as coloring products in chemical, textile, paper, printing, leather, plastics and various food industries. The need for the treatment of dye contaminated waste water passed out from the industry. In this study, Vite...
