Complementary study on the use of the potassium Reinecke's salt as a chemical actinometer
Abstract
Aqueous solutions of K[Cr(NH3)2(SCN)4].H2O (the potassium Reinecke's salt) can be used as a photochemical reference system for radiations in the visible region. The results of complementary studies on the improvement of analytical procedures, the direct synthesis of the salt and its thermal reactivity are reported. The possibilities of the application of the system are also discussed.
