Embodiment Construction

[0015] According to above-mentioned technical scheme, 2 milliliters of solutions that contain organophosphorus (pesticide) are put into the standard test tube of 5 milliliters, this test tube is put into the test tube groove of 500 volts voltage pulse discharger ( figure 2 ), then insert the voltage pulse discharge rod into the test tube containing organic phosphorus (pesticide) solution, and continue to discharge for 5 minutes to convert organic phosphorus into inorganic phosphorus, and immediately add 2 drops of 2.1% ammonium molybdate--4.9 mole / liter hydrochloric acid solution , shake well, add 1 drop of 0.1% stannous chloride-glycerin solution and 1 drop of 2 mole / liter hydrochloric acid solution, shake well, observe the change of the color of the solution in 20 seconds, blue color indicates that the solution contains organic Phosphorus, by comparing with the color of the standard color guide, the content of organic phosphorus in the solution can be obtained. The content ...

Abstract

The invention discloses a method for determining the content of organic phosphorus after rapidly decomposing and converting organic phosphorus into inorganic phosphorus, which is characterized in that the organic phosphorus in the solution is quickly decomposed and converted into inorganic Phosphorus, and then use the ammonium molybdate method to quickly determine the content of organic phosphorus. The method of the invention is reliable and effective, and is suitable for rapid detection of residual organophosphorus content in gastric lavage liquid of patients with oral organophosphorus pesticide poisoning.

Description

technical field [0001] The invention relates to a method for quickly detecting the content of organic phosphorus, in particular to a method for measuring the content of organic phosphorus after rapidly decomposing and converting the organic phosphorus into inorganic phosphorus by pulse tip discharge. This method is suitable for rapid detection of organophosphorus residues in gastric lavage of patients with oral organophosphorus pesticide poisoning. Background technique [0002] Organophosphorus pesticides are currently the most widely used pesticides in China. However, due to their high toxicity, the half-life of organophosphorus pesticides generally takes several weeks to months to degrade, and they can accumulate in animals, causing harm to the environment and humans. Greater hazard. Among them, methamidophos, dimethoate, dichlorvos, trichlorfon, methyl-1605 and other major organophosphorus pesticides all have excessive residues, especially the rapid detection of organoph...
