Batch adsorption experiments were conducted to estimate potentiality of lanthanum impregnated sawdust carbon in removing As(III) from aqueous solution. The As(III) removal was found to be function of agitation time, initial concentration, pH and temperature. The process follows first - order kinetics and endothermic in nature. For an initial concentration of 100 mg/L the uptake of As(III) increases from 7.2 to 80.2% with increase in pH from 1.0 to 12.0. The Langmuir adsorption isotherm was used… CONTINUE READING
