FIELD: process engineering.
SUBSTANCE: invention relates to analytical chemistry, namely, to separation of copper (I) and copper (II).Proposed method comprises extracting copper (I) and copper (II) from solution by complexing agent and extragent and analysing obtained extract. Note here that complexing agent and extragent represent the mix of low-melting di-antipyril-alkane and salicylic acid taken in 1:1 ratio, while extraction is carried out at HCL acidity of 0.5-7 mol/l, and obtained extract is analysed by titration.
EFFECT: higher selectivity and reliability.
