The sorptive properties of XAD-resin and Filtrasorb 300 activated carbon were compared by determination of the recovery of one hundred model compounds added to water samples at a concentration of 100 ..mu..g/l, and also the recovery of 13 compounds added to water samples at a concentration of 1 ..mu..g/l. The relative efficiencies of the two sorbents were also determined by a comparison of gas-chromatographic profiles of organic compounds recovered from real water sources of fifteen different municipal water utilities in the United States. Comparisons were also made using water samples from settling ponds at a coal mine and a coal washing plant. Use of the resin as a sorbent resulted in a greater recovery of 59 of the 100 tested compounds added to water at the higher concentration; the use of carbon was more effective for 12 of the compounds; comparable results were obtained for 7 compounds, and neither sorbent was adequate for 22 of the test substances. Out of the classes of compounds studied, resin was more effective for 9, including phthalate esters, most aromatics, and pesticides. Carbon was more effective for alkane sorption. Neither sorbent was particularly effective with acidic compounds. Although the resin appears to be superior for isolating these organic compounds from water, this work has not shown whether resins are superior to all types of activated carbon for treating drinking water. 8 tables, 1 figure.
