Abstract
The invention provides a method for carrying out non-destructive qualitative detection on copper, comprising the following steps of: wiping a part to be detected with filter paper processed by an organic liquid reagent, then spraying copper-detecting solution on the filter paper, standing for a period of time, and determining the part to be detected contains copper if the surface of the filter paper is blue, wherein the copper-detecting solution is formed by mixing bis(cyclohexanone) oxaldihydrazone organic solution with mixed aqueous solution of sodium acetate and ammonium acetate in proportion. The detection method provided by the invention is simple and is more economic and practical compared with the traditional method, and the detection speed is improved, thus the method has great value in production; meanwhile, an article to be detected is not required to be destroyed during the detection process, and the application range of the method can be greatly widened.
Description
Technical field
The present invention relates to a kind of qualitative test method of copper, particularly a kind of harmless copper qualitative test method of deciding.
Background technology
In existing production operation process, be used for detecting whether cupric of dust, can only use instrument detecting again with after the dust dissolving; For article surface cupric whether, then article surface can only be carried out destructiveness and handle, after the dissolving, use instrument detecting again, formality is very complicated, and the detecting instrument costliness, even also will destroy detected article sometimes, greatly the promptness that detects of restriction.
Summary of the invention
The present invention aims to provide a kind of method that need not destroy, operate very easy qualitative survey copper to article.
The present invention realizes by following scheme:
A kind of method of harmless qualitative survey copper is at first done moistening processing with organic liquid reagent to filter paper, wipes examination position to be detected with above-mentioned filter paper again, on filter paper, spray the copper test fluid then, after placing a period of time,, then show position to be detected cupric if the filter paper surface manifests blueness; Described copper test fluid is that 1: 1 ratio is formulated by two kinds of solution by volume, and a kind of solution is the organic solution of bisoxalydihydrazone, and another kind of solution is the mixed aqueous solution of sodium acetate and ammonium acetate.
In practical operation, the preferred absolute ethyl alcohol of the organic solution of described bisoxalydihydrazone is as solvent; Filter paper is also preferably selected quantitative filter paper for use; Be more than 20 minutes filter paper standing time of spraying after the copper test fluid.
The concentration of bisoxalydihydrazone is (1～3) mg/ml in the organic solution of described bisoxalydihydrazone.
In the mixed aqueous solution of described sodium acetate and ammonium acetate, the concentration of sodium acetate is (0.4～0.6) g/ml, and the concentration of ammonium acetate is (0.1～0.3) g/ml.
And when using certain density copper to detect liquid, also can accomplish the analysis of sxemiquantitative copper according to the preliminary deduction of the size copper content of variable color radius on the filter paper.
Than existing, detection method one of the present invention is very simple, and is not only economical and practical than existing method, and accelerated the speed that detects, and very big practical value is arranged aborning; The 2nd, do not need to destroy article to be measured when detecting, can improve the scope of its application greatly.
