Embodiment 1
[0023] 1. Prepare 9g of anhydrous potassium pyrophosphate, 18g of anhydrous disodium hydrogen phosphate, 2.5g of citric acid, and 70.5g of anhydrous sodium sulfate, and add the above raw materials into a glass mortar, and grind them sufficiently so that all raw materials can pass through an 80-mesh standard sieve , and then sub-packed into 0.2g per package to become A reagent;
[0024] 2. Prepare 10g of potassium periodate and 90g of potassium chloride, add the above raw materials into a glass mortar, fully grind all the raw materials to pass through an 80-mesh standard sieve, and then pack them into 0.2g per pack to become reagent B.
[0025] 3. Add a pack of reagent A into the water sample, and after it dissolves, add a pack of reagent B. If the water contains manganese, it will display purple, and the depth of purple is proportional to the concentration of manganese in the water. After standing for 10 minutes, it will be compared with the standard Color comparison card, col...
Embodiment 2
[0027] 1. Prepare 5g of anhydrous potassium pyrophosphate, 10g of anhydrous disodium hydrogen phosphate, 0.5g of citric acid, and 65g of anhydrous sodium sulfate. Add the above-mentioned raw materials into a glass mortar and grind them sufficiently so that all raw materials can pass through an 80-mesh standard sieve. Then sub-package into 0.2g per pack to become reagent A;
[0028] 2. Prepare 5g of potassium periodate and 95g of potassium chloride, add the above raw materials into a glass mortar, fully grind all the raw materials to pass through an 80-mesh standard sieve, and then pack them into 0.2g per pack to become reagent B.
[0029] 3. Add a pack of reagent A into the water sample, and after it dissolves, add a pack of reagent B. If the water contains manganese, it will display purple, and the depth of purple is proportional to the concentration of manganese in the water. After standing for 10 minutes, it will be compared with the standard Color comparison card, color di...
Embodiment 3
[0031] 1. Prepare 15g of anhydrous potassium pyrophosphate, 30g of anhydrous disodium hydrogen phosphate, 5g of citric acid, and 80g of anhydrous sodium sulfate. Add the above-mentioned raw materials into a glass mortar, fully grind all raw materials to pass through an 80-mesh standard sieve, and then Divide into 0.2g per package and become reagent A;
[0032] 2. Prepare 25g of potassium periodate and 75g of potassium chloride, add the above raw materials into a glass mortar, fully grind all the raw materials to pass through an 80-mesh standard sieve, and then pack them into 0.2g per pack to become reagent B.
[0033] 3. Add a pack of reagent A into the water sample, and after it dissolves, add a pack of reagent B. If the water contains manganese, it will display purple, and the depth of purple is proportional to the concentration of manganese in the water. After standing for 10 minutes, it will be compared with the standard Color comparison card, color disc or colorimeter col...
