| titleOfInvention | Total phosphorus analysis method |
| abstract | The invention discloses a total phosphorus analysis method, wherein the required reagents comprise concentrated sulfuric acid, potassium persulfate, ascorbic acid, molybdate solution and antimony potassium tartrate, and a laboratory Hash CODDDR 2800 measuring instrument and a Hash DR200 digester are used as the required instruments; the total phosphorus analysis method comprises the following steps: stpe 1: adding 5mL of ultrapure water into a blank tube (sample), respectively adding 1mL of potassium persulfate solution into the blank tube (sample) and the sample to be detected, and then shaking up to obtain a mixed solution; stpe 2: heating the mixed solution in a digestion device at 120 ℃ for 30min and then cooling; stpe 3: respectively adding 1mL of ascorbic acid solution in the second step, and after 30S, respectively adding 1mL of molybdate solution and shaking up to obtain a further mixed solution; stpe 4: standing the mixed solution for 15min, and determining. The total phosphorus analysis method is safe and convenient to operate, short in test time period and low in test cost. |
