## Abstract A flow injection (FI) method is reported for the determination of lβcysteine, based on its enhancement on chemiluminescence (CL) emission of luminol oxidized by sodium persulphate in alkaline solution. The calibration graph was linear over the range 1.0Β ΓΒ 10^β9^β5.0Β ΓΒ 10^β7^ mol/L (__r_
A reagent-injection flow injection procedure for the determination of nitrate and nitrite in water by reduction to NO followed by a membrane separation process and chemiluminescence detection, with air-stripping, is proposed. Microporous PTFE was used as a membrane to transfer NO to the gas phase af
