Orthogonal Experiments for Optimizing Adsorption of Methyl Orange from Aqueous Solution

Abstract:

The adsorption of methyl orange dye from aqueous solution was investigated with active carbon powder as sorbents. Effects of selected factors were studied through the use of L₁₆ (4⁴) orthogonal experiment for the optimal parameter. The results demonstrated that the orders of their influences were contact time > initial dye concentration > the dosage of active carbon powder > pH. It was then concluded that contact time must be given priority in removing methyl orange dye from wastewater. Under the optimum conditions (the dosage 10g, time70min, initial dye concentration 35mg/L, pH7), The active carbon powder possessed good adsorption capacity to methyl orange which the removal efficiency could reached 95.96%.
