Abstract: Recovery of fluorinated emulsifier acids (I) from waste water involves: (i) separating finely divided solids and/or components convertible into solids from the waste water; (ii) binding (I) to an anion exchange resin and (iii) eluting (I) from the resin.

Abstract: The invention relates to a method for recovering fluorinated emulsifying age nt acids from waste waters, characterized in that the finely dispersed solids i n the waste water are stabilized with a nonionic or cationic surfactant or an analogous acting surface active substance, the fluorinated emulsifying agent acids are subsequently bonded on an anion exchange resin and the fluorinated emulsifying agent acids are eluted from the latter.

Abstract: In a process to treat water used as a washing agent in photo processing, silver is recovered by an exchange of anions. The novelty is that the process incorporates: (a) a first washing water circuit in which the electrical conductivity is reduced by a continual exchange of anions; and (b) a second washing water circuit in which the electrical conductivity is further reduced by removal of salts by an exchange of cations and anions.

Abstract: The process is based on the separated recycling of two parts of an anion exchanger in the original chloride form. The first part is partially recycled by a solution containing sulphur ions, preferably in a concentration less than 0.5 mol/l. The second part is partially recycled by a solution containing hydrogen carbonate ions, preferably in a concentration less than 0.5 mol/l. Both parts are mixed together in such a ratio that the resulting representation of the functional groups in the mixture is 50 to 98 % sulphuric forms, 2 to 50 % chloride forms and 2 to 50 % hydrogen carbonate forms.

Abstract: The invention relates to a novel process for preparing bifunctional anion exchange resins by partial quaternisation of weakly basic anion exchangers containing tertiary amino groups by means of conventional alkylating agents; the process is characterised in that the weakly basic anion exchangers are partially loaded with strong acids before the quaternisation. The invention also relates to the bifunctional anion exchanger resins obtainable by this process and to their use for the desalination and decolorisation of glucose solutions.
