title: Spectrophotometric determination of cyanide by unsegmented flow methods.
abstract: Photometric methods for cyanide determination by normal and reversed FIA techniques and by completely continuous monitoring are proposed. The sampling rates for the first two techniques are 20 and 28/hr, respectively, the r.s.d. being less than 0.8% in both cases. A simulation of cyanide control in industrial waste waters shows the usefulness of the continuous monitoring method.
