Preparation and characterization of iron-exchanged redmud for arsenic adsorption efficiency

This study investigated the effectiveness of raw redmud and iron exchanged for arsenic (As) adsorption efficiency at different time intervals. Due to red mud’s low absorption percentage, alkaline nature, less specific surface area, poor selectivity, unmodified are effective than modified in capturing from contaminated environments. Iron have been developed absorb Scanning electron microscopy (SEM), Specific area (SSA), Cation exchange capacity (CEC), were used analyse morphology, composition, charge Iron-exchanged redmud. Adsorption on studied a controlled laboratory condition various times. was shown be more successful study.
