A new method for the determination of sodium thiosulfate in Disodium hexamethylene-1,6-dithiosulfate dihydrate(HTS)
Abstract: a new method for the determination of sodium thiosulfate in disodium hexamethylene-1,6-dithiosulfate dihydrate was studied and established. Firstly, the chloride ion content in the HTS sample to be tested is determined to avoid the influence of chloride ion on the test results. After removing the interfering components, the content of sodium thiosulfate in the sample can be accurately detected by a simple silver method. The detection method has the advantages of no cumbersome pretreatment process, simple operation and low cost. The interference components in the detection process of Iodometry are fully removed. The detection results are accurate and suitable for large-scale popularization and application.
Key words:Disodium hexamethylene-1,6-dithiosulfate dihydrat(HTS);Sodium thiosulfate;Detection method
