摘要
本文详细研究了氰化物蒸馏条件及其稳定性问题,建立了一个冷原子荧光法间接测定水中氰化物的方法,并用于海水及氰化液中痕量CN-的测定,结果令人满意。CN-检出限为0.02μg/mL,回收率95%~98%,变异系数7.3%~8.9%。
A cold atomic fluorescence method for the indirect determination of cyanides is described.The distillation and stabilization conditions have been studied carefully.This method has high sensitivity and good reproducibility.It has been applied successfully to the determination of trace amounts of cyanides in sea water and cyanide bath liquor.The detection limit is 0.02 μg/mL.The recovery is 95%~98%,while the variation coefficient is 7.3%~8.9%.
