Problems solved by technology

[0002] In the existing production process, to detect whether the dust contains copper, the dust can only be dissolved and then detected with an instrument; for whether the surface of the article contains copper, the surface of the article can only be destructively treated, and after dissolution , and then use instruments to detect, the procedures are very complicated, and the detection instruments are expensive, and sometimes even destroy the objects to be detected, which greatly restricts the timeliness of detection

Embodiment 1

[0012] Prepare copper detection solution according to the following steps:

[0013] The first step is to prepare liquid A: dissolve 0.1 g of dicyclohexanone oxalyldihydrazone in 100 ml of absolute ethanol, and keep it in airtight storage at a concentration of 1 mg / ml.

[0014] Prepare liquid B in two steps: Dissolve 40g of sodium acetate and 10g of ammonium acetate in 100ml of pure water and store in airtight. The concentrations of sodium acetate and ammonium acetate are 0.4g / ml and 0.1g / ml respectively.

[0015] Step 3: When in use, mix liquid A and liquid B at a volume ratio of 1:1 to clear liquid.

[0016] When detecting whether the part to be tested contains copper, first wet the quantitative filter paper with absolute ethanol, then wipe the part to be tested with the above filter paper, and then spray the above prepared copper test solution on the filter paper, after standing for 20 minutes, observe the filter paper , if the surface of the filter paper appears blue, it i...

[0019] Prepare copper detection solution according to the following steps:

[0020] The first step is to prepare liquid A: dissolve 0.2 g of dicyclohexanone oxalyldihydrazone in 100 ml of absolute ethanol, and store in airtight storage at a concentration of 2 mg / ml.

[0021] Prepare liquid B in two steps: Dissolve 50g of sodium acetate and 20g of ammonium acetate in 100ml of pure water and store in airtight. The concentrations of sodium acetate and ammonium acetate are 0.5g / ml and 0.2g / ml respectively.

[0022] Step 3: When in use, mix liquid A and liquid B at a volume ratio of 1:1 to clear liquid.

[0023] When detecting whether the part to be tested contains copper, first wet the quantitative filter paper with absolute ethanol, then wipe the part to be tested with the above filter paper, and then spray the above prepared copper test solution on the filter paper, after standing for 20 minutes, observe the filter paper , if the surface of the filter paper appears blue, it ind...

Embodiment 3

[0026] Prepare copper detection solution according to the following steps:

[0027] The first step is to prepare liquid A: dissolve 0.3 g of dicyclohexanone oxalyldihydrazone in 100 ml of absolute ethanol, and store in airtight storage at a concentration of 3 mg / ml.

[0028] Prepare liquid B in two steps: Dissolve 60g of sodium acetate and 30g of ammonium acetate in 100ml of pure water and store in airtight. The concentrations of sodium acetate and ammonium acetate are 0.6g / ml and 0.3g / ml respectively.

[0029] Step 3: When in use, mix liquid A and liquid B at a volume ratio of 1:1 to clear liquid.

[0030] When detecting whether the part to be tested contains copper, first wet the quantitative filter paper with absolute ethanol, then wipe the part to be tested with the above filter paper, and then spray the above prepared copper test solution on the filter paper, after standing for 20 minutes, observe the filter paper , if the surface of the filter paper appears blue, it ind...

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 [0001] The invention relates to a copper qualitative test method, in particular to a non-destructive copper qualitative test method. Background technique [0002] In the existing production process, to detect whether the dust contains copper, the dust can only be dissolved and then detected with an instrument; for whether the surface of the article contains copper, the surface of the article can only be destructively treated, and after dissolution , and then use instruments to detect, the procedures are very complicated, and the detection instruments are expensive, and sometimes even destroy the objects to be detected, which greatly restricts the timeliness of detection. Contents of the invention [0003] The invention aims to provide a method for qualitatively measuring copper without destroying articles and having very simple and convenient operation. [0004] The present invention realizes by following scheme: [0005] A method for non-destructive qual...
