Main Article Content
Abstract
Based on Tra Bac active carbon made from coconut shell, the paper investigates the adsorption of arsenic in water. Elements affecting the arsenic adsorption include those of pH, adsorption time, quantity and size of adsorbent materials and density of the solute. Accordingly, the optimal conditions found for the arsenic adsorption are of pH = 6÷7; equilibrium time of 60 minutes; adsorbent material of 1.0g/200ml sample; adsorbent material size 0.5-1.0mm and the adsorption in a positive correlation with the density of arsenic in the solution.
