Spectrophotometric reagent for U, Th, Zr and other metals.Indicator for the precipitation titration of SO4 with Ba. | [Uses]
Usually used in the determination of calcium in serum,has been used to evaluate calcium transport in permeabilized cells,has also been used for the spectrophotometric determination of uranium and thorium. | [Biological Activity]
Arsenazo III is a metallochromic dye. Arsenazo III is used in the determination of calcium in biological samples. It is used to evaluate calcium transport in permeabilized cells. It is also used for the detection of rare earth metals (polyvalent metal ions). Arsenazo III is used for the spectrophotometric determination of uranium and thorium. |
