Embodiment 1
[0024] This embodiment provides a method for correcting total nickel turbidity and chromaticity for automatic monitoring of water quality, comprising the following steps:
[0025] 1. Solution preparation
[0026] The steps of preparing nickel standard solution are as follows:
[0027] 1) Accurately weigh 0.1000g of metallic nickel (content above 99.9%), dissolve it in 10mL (1+1) nitric acid solution, heat and evaporate to near dryness, add (1+99) nitric acid solution to dissolve after cooling, and then transfer to 100mL capacity bottle, dilute to the marked line with ultrapure water to obtain 1000mg / L nickel standard stock solution.
[0028] 2) Accurately pipette 2ml of the 1000mg / L nickel standard stock solution into a 100mL volumetric flask, dilute to the marked line with ultrapure water, and shake well to obtain a nickel standard intermediate solution with a concentration of 20mg / L.
[0029] 3) Accurately pipette 0.1mL, 0.5mL, 2.5mL, 5.0mL, 12.5mL, and 25.0mL of the nicke...

[0053] This embodiment provides a method for correcting total copper turbidity and chromaticity for automatic monitoring of water quality, comprising the following steps:
[0054] 1. Solution preparation
[0055] Prepare copper standard solution steps as follows:
[0056] 1) Accurately weigh 0.2000g of metallic copper (content above 99.9%), place it in a 250mL Erlenmeyer flask, add 20.0mL ultrapure water and 10.0mL (1+1) nitric acid solution, heat and dissolve until the reaction speed slows down Heat slightly to dissolve all the copper, boil the solution to drive off nitrogen oxides, add ultrapure water to dissolve after cooling, then transfer to a 1000mL volumetric flask, dilute to the mark with ultrapure water, and you can get 200mg / L copper standard stock solution.
[0057] 2) Accurately pipette 10.0ml of the 200mg / L copper standard stock solution into a 100mL volumetric flask, dilute to the marked line with ultrapure water, and shake well to obtain a copper standard inte...

[0083] This embodiment provides a method for correcting total phosphorus turbidity and chromaticity for automatic monitoring of water quality, comprising the following steps:
[0084] 1. Solution preparation
[0085] The steps to prepare phosphorus standard solution are as follows:
[0086] 1) Accurately weigh 0.2197±0.0001g of potassium dihydrogen phosphate dried at 110°C for 2 hours and let it cool in a desiccator, add a small amount of ultrapure water to dissolve, transfer to a 100mL volumetric flask, add about 800mL of ultrapure water, 5.0mL (1+1) sulfuric acid, continue to dilute to the mark with ultrapure water, you can get 50mg / L phosphorus standard stock solution.
[0087] 2) Accurately pipette 10.0ml of the 50mg / L phosphorus standard stock solution into a 250mL volumetric flask, dilute to the mark with ultrapure water, and shake well to obtain a phosphorus standard solution with a concentration of 2mg / L.
[0088] 3) Accurately pipette 1mL, 2.0mL, 6.0mL, 10.0mL, 20.0...
