dc.description.abstractThe 350 nm photolysis of N,N,N',N'-tetramethylbenzidine (TMB) in anionic micellar solutions of sodium dodecyl sulfate (SDS) was studied with the aim of optimizing the photoproduced yield of TMB+ cation radicals. The effect of additives such as electron scavengers and electrolytes on the yield of TMB+ in SDS micellar solutions was investigated using electron spin resonance (ESR) and optical absorption spectroscopy. The photoproduced yield of IMB+ in SDS micellar solutions increased in the presence of chromate ions and nitrate ions at low concentrations up to 1.0 mM. However the yield decreased at higher concentrations of chromate, while it levelled off at high nitrate concentrations up to 3.0 mM. The decrease in the yield of TMB+ at relatively high chromate concentrations is attributed to the absorption of a part of the excitation light by chromate ions as seen in the optical absorption measurements. However optical absorption spectra of micellar solutions of SDS/TMB containing sodium nitrate showed no such evidence of light absorption. [...]
