It consists in substituting, for the dosing of the thiocyanate anions produced, perchloric acid (HClO4) by nitric acid (HNO3), the latter being carefully chosen regarding the chemical equilibria occurring in the aqueous medium and the moderate risks of HNO3. This substitution has been rigorously validated by carrying out the experiments in a dedicated torus batch photoreactor enabling simple treatment of experimental results from a one-dimensional model.Graphical abstractActinometry using the Reinecke’s salt: switching the perchloric acid with a less hazardous acid
