Brand: Erun environmental protection
Name: Water quality sulfite determination reagent vessel
Model Number:ERUN-SF50
Parameters: sulfite (iodimetry)
Excessive sulfite can cause harm, and sulfite testing is designed to ensure the safety of the product. In order to prevent sulfite oxidation to sulfate attached to the boiler pipe wall, resulting in blockage and corrosion, so it is very important to detect sulfite. ERUN-SF50 water quality sulfite determination reagent according to the national standard iodine measurement method supporting the reagent, can directly detect the sulfite content in the boiler water quality.
Sulfite range/(mg/L) | Repeatability/(mg/L) | Reproducibility/(mg/L) |
0~10 | 0.8 | 1.8 |
＞10~20 | 1.2 | 2.8 |
＞20~50 | 2.0 | 4.2 |
Test Notes:
1, in the sampling and titration should be performed quickly to reduce sulfite oxidation by air.
2, the water temperature should not be too high, so as not to affect the sensitivity of the starch indicator and make the result is high.
3. In order to ensure that the water sample is not contaminated, sample bottles, beakers and other glass utensils, washed with hydrochloric acid (1 + 1) before use.
Product Overview:
In the acid solution, the free iodine precipitated after the action of potassium iodate and potassium iodide oxidizes the sulfite in the water to sulfate, and the action of excessive iodine and starch appears blue is the end point.
