β¦ Synopsis
The spectrofluorimetric determination of cyanide (0.1-20 pg ml-') with pyridoxal and pyridoxal-5-phosphate by a normal flow-injection method and a stopped-flow procedure is reported. The large number of interfering species in the normal method is significantly decreased by the use of the stopped-flow method. The relative standard deviation is < 2%.
