The reaction is followed spectrophotometrically by measuring the absorbanceat 510 nm. The detection limit is 4.47×10-11 g/ml, and the calibration curve is linear inthe range of 0-0.10μg Fe(III) /25 ml with a relative standard deviation of ±3.25%. Themethod has been applied to the determination of iron in tap-water, chemical reagents andhuman hair.展开更多
U.V. irradiation of N,N-dimethylaniline (DMA) in the presence of 7,7-dichloronorcarane (DCN) in acetonitrile solution produces N-methyianiline, 4,4'-methylenebis-(N,N-dimethylaniline), N-(4'-N',N'-dime...U.V. irradiation of N,N-dimethylaniline (DMA) in the presence of 7,7-dichloronorcarane (DCN) in acetonitrile solution produces N-methyianiline, 4,4'-methylenebis-(N,N-dimethylaniline), N-(4'-N',N'-dimethylaminobenzyl)-N-methylaniline and 7-chloronorcarane as the major products. A photoinduced electron transfer mechanism is proposed.展开更多
