Manganese is one of the essential trace elements for living organisms. Manganese compounds come in various forms, and the content of manganese in environmental water samples ranges from several micrograms per liter to several hundred micrograms per liter, with few exceeding milligrams per liter. Manganese salts are not very toxic, but excessive manganese content in water can leave unsightly marks on clothing, textiles, and paper. Trace amounts of manganese present in drinking water not only affect the turbidity and color of the water, but also the taste of the drinking water. Therefore, manganese is a routine monitoring indicator for water quality. The hygiene standards for drinking water stipulate that the manganese content shall not exceed 0.1mg/L.

To eliminate the tedious operation of preparing reagents and testing processes for users, and improve detection efficiency, Havisham has launched this productWater quality trace manganese detection (low range) reagentEasy and fast operation, low testing cost.

Water quality trace manganese detection (low range) reagentTesting precautions

1. If the content is higher than the reagent range, the measured value can only be used to estimate the dilution factor and cannot be used as a test result. The sample should be diluted and then re digested before testing;

2. All new glassware used, including square colorimetric bottles, must be washed with soapy water (or cleaning powder) first, then rinsed with tap water, and soaked in a 1% -2% hydrochloric acid solution overnight (not less than 4 hours). After rinsing with pure water (or deionized water), they can be used. Before each experiment, the glassware needs to be soaked in acid and then washed with pure water, otherwise it may cause high test results and cannot be rinsed with tap water;

3. Before sampling, rinse the colorimetric bottle 2-3 times with the test solution, and then add the solution to the 10mL mark;

4. During the experiment, do not touch the bottle mouth with your fingers to avoid contamination when pouring out the solution for testing;

5. Ensure that the outer wall of the colorimetric bottle is free of stains, fingerprints, and water marks during testing to avoid affecting the accuracy of the test results;

6. The colorimetric bottle is prone to coloring, and after testing for a period of time, it needs to be cleaned thoroughly (ethanol solution can be used for ultrasonic cleaning for about 10 minutes).
