摘要
建立高效液相色谱-串联质谱法测定玩具中四溴双酚A的不确定度评定数学模型。依据GB/T 38415—2019,对塑料玩具中的四溴双酚A进行高效液相色谱-串联质谱法测定、外标曲线法定量。根据JJF 1059—2012,对实验结果的不确定度进行分析与评定。当四溴双酚A测定结果为106.9 mg/kg时,扩展不确定度为7.4 mg/kg,k=2,p=95%。不确定度评定有利于完善玩具中四溴双酚A测定结果的准确性。
A mathematic model of uncertainty evaluation for the determination of tetrabromobisphenol A in toys by high performance liquid chromatography-tandem mass spectrometry(HPLC-MS/MS)was established.According to GB/T 38415—2019,tetrabromobisphenol A in plastic toys were detected by HPLC-MS/MS and quantitated by external standard.According to JJF 1059—2012,the uncertainty of the experimental results were analyzed and evaluated.When the result for the determination of tetrabromobisphenol A was 106.9 mg/kg,the expanded uncertainty was 7.4 mg/kg,k=2,p=95%.Uncertainty evaluation is more favorable to improve the accuracy of the determination of tetrabromobisphenol A in toys.
