| الوصف: | ObjectiveA method for the detection of cyanide in vegetables and edible fungi by distillation-flow injection method was established.MethodsInnovative pretreatment method， the use of water vapor distillation technology to process the sample to effectively remove interfering impurities， and then the use of continuous flow syringe to detect the cyanide content in the distillate.Results20 samples were tested for cyanide， the detection limit of the method was 0.012 5 mg/kg，the lowest quantitative concentration was 0.037 5 mg/kg；The recovery rate was between 97.0%-103.6%；The relative standard deviation RSD （n=6） was 3.74%-4.56%.The method was compared with isonicotinic acid-pyrazolone Spectrophotometer and isonicotinic acid-barbituric acid Spectrophotometer.ConclusionThe results of distillation-flow injection method was accurate and reliable，with good repeatability and the test time was shortened. It was suitable for rapid and accurate detection of cyanide in large quantities of vegetables and edible fungi. |
