Abstract: The removal performance of arsenic was investigated by adsorption process on Linde Type X (LTX), Low–Silica Type X and Linde Type A (LTA) zeolites. The zeolites were hydrothermally synthesized in the laboratory at 100 ± 1 oC. The synthesized zeolites were characterized by X-ray diffraction (XRD), Scanning electron microscopy (SEM), FourierTransformed Infra-red spectroscopy and Thermogravimetric analysis (TGA). The removal capacity of arsenic, known to be a hazardous contaminant in drinking water that causes arsenical dermatitis and skin cancer was evaluated by adding 1.5 g of zeolites to 100 ml of wastewater. Removal efficiencies for arsenic removal after treating for 30 minutes with adsorbents ranged between 67.86–81.35 % for LTX, 67.86–86.31 % for LSX and 71.87– 96.00 % for LTA. Langmuir and Freundlich isotherms were used in analyzing results obtained from experimental studies. It was concluded that the synthesized zeolites were efficient in removing arsenic contaminated water samples. The concentrations of arsenic obtained after treatment were below the minimum contaminant levels as stipulated by the Ghana EPA.
