A simple and rapid flow injection chemiluminescence determination of cysteine with Ru(phen)32+–Ce(IV) system
چکیده انگلیسی

A new chemiluminescence system was developed for the determination of cysteine by flow injection system. This method is based on the reaction of L-cysteine with Ru(phen)32+ and Ce(IV) to produce chemiluminescence. The calibration curve was linear over the range 8.0 × 10−7 to 4.0 × 10−5 and 4.0 × 10−5 to 1.0 × 10−3 M with a detection limit of 7.0 × 10−7 M (S/N = 3). The relative standard deviation of 4.0 × 10−6 M cysteine was found 3.5% (n = 10). The influence of potential interfering substances was studied. The proposed method was successfully applied for the flow injection determination of cysteine in the real samples with minimum sampling rate of 90 sample/h.
