摘要： Disclosed is a process for removing selenium from wastewater effluent. The processd includes the steps of;(i) contacting a selenide containing wastewater and a strong-base anion exchange resin to absorb selenide on the resin;(ii) eluting the ion exchange resin with an eluant which is effective for stripping selenide therefrom; and(iii) recovering elemental selenium from the selenide containing eluate resulting from step (ii). Also disclosed is a process for regenerating the ion exchange resin by treatment of the resin with an acidic chlorate solution.

摘要： A process for recovery of zirconium from pickling solutions which have been used to treat products formed of zirconium or zirconium-based alloys, the invention particularly provides for separating zirconium from the acids contained in such solutions. The present process comprises passing the used or spent pickling solutions which contain from 1 to 50 g/l of dissolved zirconium through a column of an anionic ion-exchange resin by means of which the zirconium ions are separated from fluoride and nitrate ions originally present in the pickling solutions. Approximately 90% of the zirconium contained in such solutions can be recovered according to the invention, it being further possible to recycle residual fluoride and nitrate ions which remain in the used pickling solutions.

摘要： A method of regenerating strong-base anion exchange resins which have been used in the extraction of complex anions followed by elution with a thiocyanate strip solution is provided. The method involves the use of ferric ions in a regenerating solution together with a substitute anion for attachment of the resin, the regeneration taking place under conditions in which ferric-thiocyanate complex cations are formed and washed from the resin by the regenerating solution. The thiocyanate can be recovered by neutralizing the regenerating solution to precipitate ferric hydroxide and leave thiocyanate in solution.

摘要： A process is described for the recovery of uranium from ore wherein the ore is leached, the resulting leachate is passed over an anion exchange resin, and the resin is then eluted with an elution solution containing an anion capable of replacing the uranyl anion captured on the resin, followed by treatment with a sulfite-containing solution so that polythionates captured on the ion exchange resin are reacted to form essentially thiosulfate and trithionate. Preferably, the sulfite solution also contains other anions.

摘要： The invention relates to a method for converting strong-base anion exchange resins from the monovalent anion form to the hydroxide form. A .�.solution.!. .Iadd.source .Iaddend.of polyvalent anions is first passed through the resin to displace the monovalent anions. A solution of alkali metal hydroxide is then passed through the resin to convert it to the hydroxide form, and to produce an effluent solution of hydroxide ions and polyvalent anions. This effluent solution is then neutralized with an acid containing .Iadd.a source of .Iaddend.polyvalent anions, and the neutralized solution is passed through a second batch of resin in the monovalent anion form. In the preferred embodiment, a portion of the effluent is retained without neutralization and is delivered to the second batch of resin after the neutralized effluent to perform a portion of the hydroxide regeneration.

摘要： The present invention relates to a method of reducing the concentration of contaminant ions, preferably nitrates ions, in impure water. The method comprises steps of: a) passing the impure water through an ion exchange resin to substitute regenerant ions from the resin for dissolved contaminant ions; b) passing a relatively dilute aqueous solution of wash-out ions through said resin to substitute wash-out ions for contaminant ions bound to the resin and; c) passing a relatively concentrated aqueous solution of regenerant ions through said resin to substitute regenerant ions for wash-out ions bound to the resin. The affinity of the resin to wash-out ions diminishes from being greater than that for contaminant and regenerant ions when exposed to a relatively dilute ionic solution to being less than that for said contaminant and regenerant ions when exposed to a relatively concentrated ionic solution. The method allows simplified ion exchange apparatus to be utilized, since the raw water, wash-out solution and regenerant solution may all be passed through the ion exchange resin in the same direction.

摘要： Spent aqueous liquor containing cyanide, as from ore treatment, is passed through a bed of suitable anion-exchange resin to segregate the cyanide, which is subsequently recovered in regeneration of the resin by weak alkaline solution. Both the eluted cyanide and the alkaline regenerant are recycled, if desired, for further ore treatment. A most important benefit of such procedure is nearly complete elimination of cyanide as a component of the treatment effluent. Free cyanide may be separated from complexed cyanides when present by using weak alkaline regenerant to elute the free cyanide from the resin and stronger alkaline regenerant to elute the complexed cyanides.
