Laterite soil was used as an adsorbent for arsenic removal from contaminated groundwater. Effects of pH, adsorbent dose, adsorbent size, contact time, initial arsenic concentration and presence of interfering species on arsenic removal were found out. Laterite soil was found to be very effective for arsenic adsorption. It was found that 4 h contact time was sufficient for approximately 98% and approximately 95% removal from the contaminated water samples at an adsorbent dose of 10 g/L and 20 g… CONTINUE READING
