FIELD: chemistry.
SUBSTANCE: invention relates to analytical chemistry. The method of analytic detection of copper, lead and cadmium in a sample involves contacting the sample with zinc, pre-deposited on a high-basic anionite JRA-400 from a water-acetone solution and detection of the said elements using diffuse reflectance spectroscopy method at wavelengths 630 nm, 510 nm and 570 nm for copper, lead and cadmium, respectively.
EFFECT: is design of new efficient solid phases for concentrating and quantitative determination of heavy toxic metals in water of different origins and dairy products.
