متن کاملRemoval of Brilliant Red from Aqueous Solutions by Adsorption on Fish Scales
Removal of brilliant red (C. I. Reactive Red 2) from aqueous solutions by adsorption on fish scales of Labeo rohita was investigated. Batch adsorption experiments were carried out under different experimental conditions such as contact time, initial concentration of dye solutions, temperature and pH of the solution. The optimum pH for the adsorption experiment was found to be 7.2. The equilibri...
متن کاملArsenic removal from aqueous solution using ferrous based red mud sludge.
Ferrous based red mud sludge (FRS) which combined the iron-arsenic co-precipitation and the high arsenic adsorption features was developed aimed at low arsenic water treatment in rural areas. Arsenic removal studies shown that FRS in dosage of 0.2 or 0.3g/l can be used effectively to remove arsenic from aqueous solutions when initial As(V) concentration was 0.2 or 0.3mg/l. Meanwhile, turbidity ...
متن کاملArsenic removal from aqueous solutions by adsorption onto iron oxide/activated carbon magnetic composite
In this work the adsorption features of activated carbon and the magnetic properties of iron oxides were combined in a composite to produce magnetic adsorbent. Batch experiments were conducted to study the adsorption behavior of arsenate onto the synthetic magnetic adsorbent. The effects of initial solution pH, contact time, adsorbent dosage and co-existing anionic component on the adsorption o...
