- 摘要：
FIELD: chemistry.SUBSTANCE: invention can be used for semi-quantitative determination of cobalt (II) and copper (II) concentration is natural, sewage waters and various liquids under field conditions. Method includes filling glass tube with internal diameter 0.5 cm with Na-form of cation exchanger KB-2E-10 with weight 0.2 g, with further filling with analysed solution, which contains added to it sodium nitrate with concentration 1 mole/l and calcium nitrate to create medium, and estimation of cobalt and copper concentration by length of coloured zone of cation exchanger with the following content of components after tube filling, wt %: cation exchanger KB-2E-10 - 0.8; sodium nitrate - 8.5; calcium nitrate - 0.25; water - the remaining part.EFFECT: increase of accuracy and reliability and simplification of analysis.1 ex, 2 dwg
