Method for measuring moisture content in cleaning agent

The invention discloses a method for measuring the moisture content in a cleaning agent, and relates to the technical field of analytical testing. The method for measuring the water content in the cleaning agent is simple in step, high in sensitivity, good in repeatability, short in analysis time and accurate and reliable in data; compared with a Karl Fischer method, the method for measuring the moisture content in the cleaning agent has the advantages that the used reagents are low in toxicity, small in dosage and small in harm to human bodies, environmental pollution is reduced, batch testing can be carried out, and the testing efficiency is improved; compared with an external standard method and an internal standard method, the method for measuring the water content in the cleaning agent has the advantages that the reagent dosage is small, a working curve does not need to be prepared, the uncertainty introduced in the preparation process is reduced, and data are accurate; according to the method, GC-TCD is
