Current methods of determination of chlorine in inorganic substances (Overview)

Abstract

This is an overview of current methods of determination of chlorine in inorganic substances published in the last decade. Challenges of development of ICP-AES for determination of chlorine in aqueous media are demonstrated. Attention is paid to methods of determination not only of total chlorine and chloride ion, but to other forms of chlorine occurrence as well. Particular importance of determination of perchlorate ion is highlighted. Widely applied methods of ion chromatography, potentiometry, and spectrophotometry are presented in combination with flow analysis.
