摘要
FIELD: analytical chemistry.;SUBSTANCE: proposed reagent contains trilon, solution of dark blue chromic indicator and solution of agent for forming alkaline medium in three versions for different ranges of hardness. Used as agent for forming alkaline medium is agent containing aliphatic amine of the following formula RNH2, R2NH or R3N, where R=CnH2n+1 or R=CnH2nOH which are normal or branched at n=2-4. All components of reagent are combined in single aqueous solution at the following relationship in g per 100 cu cm of bidistilled water: trilon, depending on total hardness, indicator, 0.04 to 0.15 depending on total hardness and aliphatic amine, 10.00-10.80.;EFFECT: enhanced accuracy and reproducibility of results.;6 cl, 12 tbl
