Abstract
A kind of method with gold and palladium in the chelating resin recovery electroplating effluent.The chelating resin that uses in this method is mercapto-amine type resin, in the solution acidity scope of broad, the gold and the absorption of palladium is had high selectivity, high-adsorption-capacity and adsorption rate.The method of the invention is compared with electrolysis, ion-exchange etc., also has advantages such as product purity is high and easy and simple to handle.
Description
The invention relates to the method that reclaims noble metal in the electroplating effluent with macromolecular compound.
Gold and palladium are expensive metals, are widely used in electroplating industry.In order to economize in raw materials, reduce production costs, must from electroplating effluent, reclaim gold and palladium.The recovery gold commonly used and the method for palladium have electrolysis, ion-exchange etc.These methods are because operating process is longer, and step is more, and technology is complicated, and because selectivity is difficult to Ex-all than official post impurity, so it is not high to reclaim the purity of product.In recent years, the research worker begins the gold in the chelating resin recovery electroplating effluent on probation.Document was also once reported the absorption property of some chelating resins to noble metal, and was mainly as follows:
1. United States Patent (USP) (patent No. 467,995) report commodity are called Srafion NMRR, and its primary structure is
The type resin is respectively 1.1g/g resin and 0.24g/g resin to the gold and the adsorption capacity of palladium.
2.G.V.Myasoedova, et al., Zh.Anal.Khim, 27,2004(1972); 28,1550(1973); 29,2104(1974) report is a carrier with the polystyrene, and its primary structure is
Thiocarbamide type resin.Chen Yiyong etc. are once with the gold in this resin recovery electroplating effluent, and adsorption capacity is 0.82g/g resin (seeing " the academic free paper session of macromolecule gives the seal collection ", P.582(1983) (Hangzhou)).
3.G.V.Myasoedova, etal., Zh., Ahal., Khim., 28,1550(1973) the report primary structure is
But gold, silver, palladium, the platinum of mercaptoquinoline type resin enrichment Gamma Magnitude.
4. river and mountain are rich bright etc., Japanization association will, and 1760(1979) the report primary structure is
But above-mentioned resin is applied to reclaiming gold in the concrete electroplating effluent and palladium then is not reported.
The present invention is with the gold in the mercapto-amine-type chelating resin recovery electroplating effluent and the method for palladium.The main points of this method are to utilize this resinoid in the acidity scope of broad, to gold and the suction-operated of palladium with high selectivity, in gold that contains other metal ion and palladium solution, by resin column gold and palladium preferentially are adsorbed, can reach the purpose of recovery and purifying simultaneously.
The resin that uses in the method for the invention is to have
Or
The cross-linking type insoluble resin of group.The gold and the palladium that this resinoid are used for reclaiming electroplating effluent have the following advantages:
1. gold, palladium and silver are had high adsorption capacity and adsorption rate, and can in the acidity scope of broad, use.Adsorption capacity (gram metal/gram resin) is respectively gold: 1.0～1.1, palladium: 0.24～0.45, silver: 0.5～0.6.For concentration is 1 milligram/1 milliliter the gold or the acidic aqueous solution of palladium, and when solution PH was 1～6, the adsorption rate of gold and palladium was 98～99.5%.When solution acidity was 1～5M HCl, the adsorption rate of palladium was greater than 99%, and the adsorption rate of gold is greater than 95%.
2. the absorption to gold and palladium has high selectivity.In the solution that contains gold, molybdenum, chromium hybrid ionic, preferential adsorption gold and do not adsorb molybdenum and chromium; In the solution that contains palladium and tin hybrid ionic, the preferential adsorption palladium.
3. behind this type of resin adsorption gold, available thiourea solution carries out desorb, and desorption efficiency is 100%, and resin is renewable, reuses.
The method and the existing electrolysis of gold and palladium in the recovery electroplating effluent of the present invention, ion-exchange etc. are compared, and have easy and simple to handle and the high advantage of recovery product purity.
Be specific embodiments of the invention below:
Take by weighing resin 3.357 gram dress posts, with Au
3+, Mo
2+And Cr
3+Hydrochloric acid (2N) solution pass through adsorption column.To saturated absorption, use watery hydrochloric acid and distillating washing resin respectively.Resin is changed in the porcelain crucible, first ashing resin, 900 ℃ of calcinations 2 hours in muffle furnace again, then gold 3.6283 grams, recyclable gold 1.08 grams of promptly every gram resin.Through the atomic absorption method analysis, confirm to reclaim no molybdenum and chromium in the gold.Measure the purity that reclaims gold with the x-photoelectron spectroscopy, the result is: the percetage by weight of gold is 100, and atomic percentage is 100, standard error 0.91%.
Claims (2)
1, reclaims the method for gold and palladium in the electroplating effluent with chelating resin.The chelating resin that the invention is characterized in use is for having
, the mercapto-amine-type chelating resin of group.
2, by the described method of claim 1, also can be used for reclaiming gold and palladium in other solution.
