Abstract
Способ определения меди в природных и питьевых водах, включающий концентрирование меди на сорбционном материале, помещенном в патрон, путем пропускания через него анализируемой пробы, элюирование меди азотной кислотой и определение меди методами атомной спектроскопии, отличающийся тем, что концентрирование меди проводят на сшитом N-2-сульфоэтилхитозане со степенью замещения 0,5 со скоростью пропускания пробы через патрон 1,0-2,0 мл/мин, а элюирование осуществляют раствором азотной кислоты с концентрацией 0,1 моль/л, при этом раствор азотной кислоты пропускают через патрон со скоростью 1,0-2,0 мл/мин.A method for determining copper in natural and drinking waters, including concentrating copper on a sorption material placed in a cartridge by passing an analyzed sample through it, eluting copper with nitric acid and determining copper by atomic spectroscopy, characterized in that the copper is concentrated on crosslinked N-2 -sulfoethyl chitosan with a degree of substitution of 0.5 with a sample transmission rate through the cartridge of 1.0-2.0 ml / min, and the elution is carried out with a solution of nitric acid with a concentration of 0.1 mol / l, while the solution is nitric isloty passed through the cartridge at a rate of 1.0-2.0 ml / min.
