Use of isocyanates for assaying nucleophilic functions in the form of traces in wet medium |
摘要 |
A method for detecting traces of pollutant in aqueous media, wherein the method includes the use of isocyanates to react on the nucleophilic functions in the form of trace amounts in a wet medium. The method for assaying nulceophilic functions in a wet medium includes the following steps: adding isocyanates to an aqueous solution of basic pH containing the nucleophilic functions to be tested; maintaining the solution for an interval ranging from a few minutes to several dozens of minutes at a temperature lower than 100° C.; and assaying the resulting carbamate, thiocarbamate or urea.
