Abstract: A process for the liquid phase adsorptive separation of phenylalanine from a fermentation broth containing phenylalanine salts, carbohydrates, amino acids and organic acids. The feed is contacted, at a pH of 4.5-6.5, with a hydrophobic polar, porous synthetic adsorbent, such as Amberlite XAD-7, whose functional groups have a dipole moment of 1.6-2.0, to selectively adsorb the phenylalanine onto said adsorbent to the substantial exclusion of the other feed components and recovering phenylalanine by desorbing with water, an alcohol, a ketone or an ester.

Abstract: The discharge of copper from isothiazolone biocides into industrial waste water streams is prevented by contacting the isothiazolone biocide as it is withdrawn from a point of use storage container with an ion exchange resin capable of removing copper from aqueous solutions. When the treated isothiazolone biocide is added to an industrial process water which will produce waste stream, potential copper contamination is virtually eliminated.
Abstract translation: 将异噻唑酮杀生物剂排出到工业废水流中可以通过使异噻唑酮杀生物剂从一个使用的储存容器中取出并与能够从水溶液中除去铜的离子交换树脂接触来防止。 当将经处理的异噻唑酮杀生物剂加入到产生废物流的工业过程中时，几乎可以消除潜在的铜污染。

Abstract: A method is described for removing ferrometal corrosion products from cooling water systems, which method recycles ferrous/ferric complexing agents and leads to low volume highly concentrated iron wastes for disposal. The method combines, preferably, the use of citric acid or citric acid-tannin complexing agents with erythorbic acid reducing agents to clean corroded surfaces followed by recovery of both complexing and reducing agents for recycle by contacting spent cleaning solution with strong acid cation exchange resins or chelating resins. The resins remove and retain iron species, releasing chelating and reducing agents to resin bed effluents. These are recycled. A concentrated iron waste stream is recovered by regenerating the resin beds with strong acids, preferably HCL, H.sub.2 SO.sub.4, and the like.
