| titleOfInvention | Preparation and application method of detection sheet for measuring phosphate content of water quality |
| abstract | The invention relates to a preparation and application method of a detection sheet for measuring the phosphate content of water quality. The method comprises the following steps of: firstly mixing concentrated sulfuric acid, sodium sulfate and sulfamic acid to obtain mixed powder I; uniformly mixing sodium ascorbate, polyethylene glycol 6000 and polyvinylpyrrolidone K-30 to obtain mixed powder II; uniformly mixing ammonium molybdate, polyethylene glycol 6000 and polyvinylpyrrolidone K-30 to obtain mixed powder III; and pressing the mixed powder I, the mixed powder II and the mixed powder III into a three-layer tablet to form a detection sheet for measuring the phosphate content of water quality. When in use, the detection sheet is directly immersed in 10ml of water sample which is then slightly shaken for 5-10 minutes until the detection sheet is dissolved; and then reaction lasts for 5-20 minutes, and a portable spectrophotometer is adopted for measurement. The detection sheet prepared by the method provided by the invention is convenient to carry and easy to store; when in use, any reagent is not required, and the result is accurate and reliable; and the detection sheet is suitable for the field detection of phosphate of water bodies such as surface water, domestic sewage, industrial wastewater and the like. |
