“…According to the literature [12,13,[18][19][20][21], the results obtained by using anion-exchange resins (percolated volume, concentration factor, recovery yields: 90 -100%) are comparable to those obtained with non-specific sorbents. So, ion-exchange resin extraction would not be affected by interfering compounds from the organic or mineral matrices.…”

Abstract. The objective is to concentrate organic acid traces in water samples. The influence of several parameters and their interactions on the adsorption of organic acids on anion exchange resins was studied. A complete factorial design 2 4 was hence performed. The measured response corresponds to the maximal percolation volume and the studied parameters were the nature and the mass of the resin, the percolation flow-rate and the ionic strength of the analysed water. The results shown that the percolation flow-rate is significant but not really important compared to the resin mass and to the nature of water. Indeed, the sample inorganic anions can compete with organic acids. This adsorption competition appears to be more important when a macroporous resin is used. A "gel-type" resin could be therefore better adapted to the extraction of organic acids in water samples.

5′-Chloro-5-dodecyl-2,4,2′-trihydroxyazobenzene (CDTA) impregnated XAD-4 resin (CDTA resin) was prepared, and applied to the preconcentration of trace aluminum from environmental water samples with satisfactory results. Aluminum was measured by flow-injection analysis (FIA) with fluorescence detection by using lumogallion after the preconcentration of aluminum with CDTA resin. Fe 3+ and other coexisting substances had no interference on the determination of aluminum by the present method. Chemical speciation of trace aluminum in environmental water was carried out by using the CDTA resin after the separation of aluminum species with ionic exchangers without changing the pH. About 50% of water-soluble aluminum in Lake Biwa was found to be aluminum organic species (anion species).

“…The absorption of phenols from acidic solution on porous polymer resins such as Amberlite XAD-2 has been shown to form the basis for a simple and accurate method for determining organics, including phenols, in water (42,43). XAD-2 resin effectively sorbs phenols and other organic compounds from water, although low recoveries are obtained for phenol itself.…”
