Embodiment
[0060] In this embodiment, copper ions are selected as the test target for system verification, and the test design is carried out with reference to GBT4.4.1-4.4.7, the absorption peak and absorption peak curve of the chelate solution are detected, and the linear relationship between the absorption peak frequency and absorbance and the solution concentration is observed.
[0061] Proceed as follows:
[0062] (1) Ammonia water, acetaldehyde 40%, triammonium citrate solution 400g / L: Weigh 40g of triammonium citrate, dissolve in pure water, and dilute to 100ml;
[0063] (2) Dicyclohexanone oxalyldihydrazone solution 2g / L Weigh 1g of dicyclohexanone oxalyldihydrazone, put it in a beaker, add 500ml ethanol (1+1) solution;
[0064] (3) Heat to 60°C-70°C and stir to dissolve;
[0065] (4) Ammonia water-ammonium chloride buffer solution (pH9.0) Weigh 27g of ammonium chloride, dissolve in 500ml of pure water, add ammonia water (ρ=0.88g / ml) dropwise until pH=9.0;
[0066] (5) Copper s...
