Ion chromatography is an analytical method mainly used for the analysis of inorganic ions in water, including analysis of halogenous impurities and standard anionic materials in tap water.
Simultaneously, the World Health Organization and the US Environmental Protection Agency also recommended exposure limits and risk assessment of halogenous compounds [6].
MPO can also use other (pseudo-) halide anions including [Br.sup.-], [I.sup.-], and [SCI.sup.-] to give the corresponding hypo(pseudo-) halogenous oxidants (Figure 1).
