Способ определения меди в природных и питьевых водах: патент на изобретение

Translated title of the contribution: METHOD OF IDENTIFYING COPPER IN NATURAL AND POTABLE WATER: patent of invention

Research output: Patent

Abstract

FIELD: chemistry.
SUBSTANCE: method includes copper concentration on a sorption material, placed in a cartridge, by passing samples to be analysed through it, elution of copper with nitric acid and identification of copper by methods of atomic spectroscopy. The concentration of copper is carried out on cross-linked N-2-sulphoethylchitosan with a degree of the substitution equal to 0.5 with the rate of the sample passing through the cartridge of 1.0-2.0 ml/min. Elution is realised with a nitric acid solution with the concentration of 0.1 mol/l. The nitric acid solution is passed through the cartridge at a rate of 1.0-2.0 ml/min.
EFFECT: method makes it possible to increase the efficiency of copper concentration and expressiveness of copper identification in natural and potable water.
