At pH=10.40, in the presence of Triton X-100, ABNPDT react with cadimum to form a red Complex. The maximum absorption of reagent and complex are at 430nm and 520NM respectively. The molar absorpitivity is 2.0710 5L·mol -1 ·cm -1 . Berr’s law can be applied in the rang of 0～12μg/25ml. This method was used to determine tarce cadmium in water with satisfactory results.展开更多

The organic ligands do not coordinat5e with heteropolyanions, but with Protons in heteropoly acid by coordination bond. Photochromism studies show that the electron transfer takes place from the organic molecules to the heteropolyanions.展开更多
