摘要：
The invention concerns a mixture in solid form containing: dithiocarbamoyldithiocarbazate of formula (I): H2N-(C=S)-NH-NH-(C=S)-S-M+, wherein: M+ represents an alkaline cation or an ammonium and a xanthate of formula (II): R-O-(C=S)-S-M+, wherein R represents a C¿1?-C12 hydrocarbon group, optionally branched or unsaturated, optionally cyclic or aromatic, and M?+¿ represents an alkaline cation or an ammonium. The invention also concerns a method for making said mixture. The invention further concerns the use of said solid mixture and basic solutions containing said mixture as brightening agent in electrolytic solutions, in particular in cyanide-containing baths, for electrodeposit of silver, gold or one of their alloys.
