Isolation of organic acids from large volumes of water by adsorption on macroporous resins Isolation of organic acids from large volumes of water by adsorption on macroporous resins

Adsorption on synthetic macroporous resins, such as the Amberlite XAD series and Duolite A-7, is routinely used to isolate and concentrate organic acids from forge volumes of water. Samples as large as 24,500 L have been processed on site by using these resins. Two established extraction schemes using XAD-8 and Duolite A-7 resins are described. The choice of the appropriate resin and...
