Abstract
The determination of human exposure to polar volatile and semivolatile organic compounds is an area of increasing importance to EPA. Since the bioavailability of many polar compounds is greater than for relatively non-polar compounds, methods are needed for the selective sampling and analysis of these types of compounds. The anion exchange resin AG MP-1 was evaluated for selective collection and retention of vapor phase phenolic compounds. The primary goal of the program was development of sampling and analysis conditions which would permit detection and quantification of diverse phenolic and hydroxylated species at ambient levels of 1 ppbv. Phenols (and other acidic compounds) are retained on AG MP-1 by formation of a chemical bond; the reaction is reversed to liberate the phenols from the sorbent prior to analysis. Because of the dominant concern about collection and recovery, investigations here centered upon those parameters which affect the formation of the initial chemical bond between phenolic analyte and sorbent and those procedures that allow subsequent reversal of these reactions for quantitative recovery of analytes in the laboratory.
