Adsorption Capacity of Cr(VI) by Modified Fly Ash from Aqueous Solution

Abstract:

Various parameters (time, initial concentration, pH value and temperature) are investigated. The results show that with increasing the temperature decreased the absorbance. The optimal condition is that the maximum adsorption is 0.47mg•g-1 at303K, pH 1. Adsorption process fits the Langmuir isotherm equation, the adsorption reaction is exothermal reaction.
