FIELD: analytical chemistry. SUBSTANCE: for simultaneous qualitative and quantitative assay of metals in plant raw (fruits, berries, atmospheric deposits, ash, juice, intermediate wine etc.) these materials were treated at pH 4-6 with complexing agent. Prepared suspension is passed through the glass filter, concentrate is dissolved in acetonitrile and obtained metal chelates were separated by column chromatography method. Column is filled with reverse-phased sorbent following by detection in UV-region (dual-wave detection). Used mobile eluent phase is a mixture of acetonitrile/buffer solution (pH 5.4)/Na-ДЭДТК-chloroform. EFFECT: improved method of assay. 1 tbl
