Chemiluminescence during the reaction of siloxene with cerium(IV) sulfate
By: Grigorenko, F. F.; Dubovenko, L. I.
The intensity of luminescence of siloxene (polymd. siloxane (Si6O3H6)n) in the presence of Ce(IV) is greater in H2SO4 than in HCl or HNO3. It also is max. if the ratio of siloxene to Ce(IV) is one Si6O3H6 unit per ion. A scale for detg. Ce is prepd. by adding 0.05 to 0.35 ml. 0.002M Ce(SO4)2 to enough M H2SO4 contg. 0.02 g. siloxene to make 2 ml. The cuvette is placed before the window of the photomultiplier before mixing. The max. in the light emission is plo…
