The research was focus on adsorption efficiency of sulfate by absorbent containing calcium carbonate including lime oyster powder fine ash and bottom ash from municipal incinerator. Batch experiment were performed as a function of pH, adsorbent dosage, contract time and initial sulfate concentration. The results revealed that all adsorbent materials had the ability to absorb sulfate. At the concentration of 1,000 mg SO42-/L, the adsorption efficiencies were 22.45 – 46.19%, and the sulfate adsorption capacities were 110.71 – 215.06 mg/g. The fly ash had the highest absorption efficiency. The optimum condition was 3 g/L of adsorbent, pH of wastewater was 3, and contact time was 30 minutes. The results of adsorption processes of sulfate on the surface of each type of adsorbent showed that lime and fly ash were better correlated to the Freundlich adsorption isotherm. Which shown that the adsorption was multi-layer adsorption or physisorption. Whereas, oyster powder and bottom ash were well fitted with the Langmuir adsorption isotherm, which indicated that adsorption was monolayer adsorption on a homogenous surface or chemisorption.
