Method:Because DDC in the sample was unstable and difficult to determine directly, p -bromophenacyl bromide( p -BPB)was used to react with DDC and the derivatization product was determined by RP-HPLC with ultraviolet detector.
方法 :由于样品中二乙基二硫代氨基甲酸不稳定 ,且难以直接测定 ,故以对溴苯甲酰甲基溴进行衍生化并检测其衍生化产物 ,选用反相高效液相色谱 -紫外检测法定量。
