Methods IO(superscript - subscript 3) was prepared by quantitative oxidation of bromine water, with the excessive bromine removed with formic acid. In the presence of excessive iodide, I(superscript -) would be oxidized by I(superscript - subscript 3) to form 3 times of I(superscript - subscript 3) in mol, displaying maximal absorption at 286nm in ultraviolet zone and a slightly low apex at 345nm.ε286=1.3×10^5 Lmol^(-1)cm^(-1),ε345=8.1×10^4 Lmol^(-1)cm^(-1), with both showing high sensitivity.
