| Abstract: | Conclusions The process of regenerating KU-2-8 resin with precipitation baths from viscose manufacturing has been investigated as compared with regeneration with sulfuric acid.It has been found that desorption of zinc from the resin by precipitation baths is rather efficient, which makes it possible to use precipitation bath in the regeneration process instead of 10% sulfuric acid solution.It has been shown that a high content of organic contaminants in the precipitation baths (COD of 2000–5661 mg O2/liter) does not affect the sorptive properties of KU-2-8 resin.Translated from Khimicheskie Volokna, No. 6, pp. 9–10, November–December, 1984. |
