| titleOfInvention | A kind of detect manganese and the method for inorganic compound content thereof in working environment air |
| abstract | The present invention proposes a kind of to detect manganese and the method for inorganic compound content thereof in working environment air, makes that the first glass fiber filter paper is electronegative, the second glass fiber filter paper positively charged；Keep, between the first glass fiber filter paper and the second glass fiber filter paper, there is clearance for insulation to sample；First glass fiber filter paper and the second glass fiber filter paper ensure windward side upward, the most steadily put into the first beaker, and add phosphoric acid and be completely dissolved；In the first beaker, add clear water dilute and heat, then solution is filtered；Take part solution to be measured in the second color comparison tube；Make the 4th blank color comparison tube and the standard pipe of many groups standard solution containing variable concentrations manganese dioxide；In the second color comparison tube, the 4th color comparison tube and each standard pipe, it is separately added into Potassium metaperiodate., and heats until each solution reaches spectrophotometric colorimetric condition in boiling water bath；Carry out colorimetric assay.Thus, the present invention can reach manganese and inorganic compound content detection thereof in the most efficient working environment air. |
