Photometric Determination of the Nickel and Copper Macroquantities in Natural and Industrial Subjects in the Form of Ethylendiaminotetraacetates
The optimum conditions of formation are found and the chemico-analytical characteristics ethylendiaminotetraacetates (complexonates) nickel, copper, cobalt, iron, titan, chrome, vanadium are determined. With use two-wave spectrophotometry the techniques of definition nickel and copper in objects of various structure are developed. The metrological characteristics do not concede received at use of classical methods of the analysis, but the techniques considerably surpass them in productivity
