chlorophosphonazo iii BiologicalActivity
| Description | Chlorophosphonazo III is a sensitive reagent for both calcium and magnesium. It is possible to determine calcium alone at pH 2.2 and calcium and magnesium at pH 7.0. Chlorophosphonazo III can also be used for the spectrophotometric determination of titanium, zirconium, thorium, and scandium, quinquevalent actinide elements, and protactinium[1]. |
