摘要：
A rapid, simple and sensitive fluorimetric method has been developed for the determination of cyanide with fluorescein as fluorogenic reagent (lambda(ex) = 494 nM, lambda(em) = 514 nm) at pH 6.0-7.0. A linear calibration curve was obtained in the range 0.004-2.0 mu g CN-/25 ml. The detection limit is 0.004 mu g CN-/25 ml. The method was successfully applied to the determination of cyanide in waste water.
