Comparison of three sorbents for organic pollutant removal in drinking water

摘要

Removal effects of organic pollutants in drinking water by activated carbon, haydite and quartz sand were studied with the method of solid-phase extraction (SPE) and GC-MS analyzing in this study. There were 42 species organic pollutants in 11 categories detected in drinking water. The removal rates of total peak area of organic pollutants by activated carbon, haydite and quartz were 70.35%, 29.68% and 37.36%. Among all, activated carbon showed the best removal effect to most organic pollutants contents, and quartz sand to species. So if activated carbon - quartz sand combined processes were adopted, organic pollutants species and totalpeak area could be reduced simultaneously.
