title: Determination of small concentrations of HCl by derivative formation-a problem and how it might be solved.
abstract: In the investigation of methods for the determination of chloride three reactions for making derivatives of HCl have been developed. The individual problems which arise for the different methods are discussed. The reactions are reaction of CrO(3) with HCl to give CrO(2)Cl(2), reaction of epoxides with HCl to produce alpha-chloro-alcohols and reaction of C(6)H(5)HgNO(3) with HCl to form C(6)H(5)HgCl. The detection methods used are gamma-spectrometric measurement of (51)Cr-labelled CrO(2)Cl(2), gas-chromatographic determination of alpha-chloro-alcohols with flame-ionization, electron-capture or electrolytic-conductivity detectors and the determination of C(6)H(5)HgCl by AAS.
