Detecting and determining fluoride ion or hydrofluoric acid, useful e.g. for analysis of air, water and foods, based on hydrolysis of a silylated organic compound

摘要

Method for detecting and/or determining fluoride ion and/or hydrogen fluoride in a sample comprises contacting the sample, in aqueous solution, with a silyl compound (I) and determining and/or detecting, in the solution, either appearance of a desilylated organic compound (Ia) or disappearance of (I), processes that occur if fluoride or HF is present in the sample. (I) and (Ia) can be detected or determined independently of each other. An independent claim is also included for a kit for the new method that contains (I) and a system for detecting appearance of (Ia) and/or disappearance of (I).
