Chlorophosphonazo III
Colorimetric Reagent
Chlorophosphonazo III is a sensitive colorimetric reagent primarily used for the detection of calcium and magnesium ions. At pH 2.2, it allows for the selective determination of calcium, while at pH 7.0, it can discriminate between both calcium and magnesium ions. Additionally, Chlorophosphonazo III is applicable for the spectrophotometric analysis of various metal ions, including titanium, zirconium, thorium, and scandium, as well as certain quinquevalent actinide elements like protactinium.
