| titleOfInvention | Method of destructing anion of 1-hydroxyethane-1,1-diphosphoric acid in production wastes |
| abstract | FIELD: chemistry. n SUBSTANCE: invention relates to methods of deactivation of toxic wastes of galvanic and radio-electronic production and can be applied for deactivation of waste solutions of galvanic and chemical metal coatings, which contain anion of 1-hydroxyethane-1,1-diphosphonic acid, as well as for neutralisation of waste solutions of etching of printed circuit boards, which contain ammonium perpxodisulphate. Method consists in mutual neutralisation of two liquid wastes of production as a result of oxidation of anion of 1-hydroxyethane-1,1-diphosphonic acid by peroxodisulphate to nontoxic chemical substances. n EFFECT: method makes it possible to convert more than 99% of anion of 1-hydroxyethan-1,1-diphosphonic acid into orthophosphate, reduce material costs for neutralisation of toxic wastes of production of galvanic coatings and printed circuit boards and extend arsenal of methods for utilisation of waste solutions of etching of printed circuit boards, which contain ammonium perpxodisulphate. n 11 cl, 4 dwg, 4 ex |
