摘　　要：文章建立以人工唾液为萃取介质,测定纺织品及纺织品附件中铅释放量的试验方法,优化样品前处理条件和测试仪器参数。试验结果表明:采用电感耦合等离子体发射光谱法测定的定量限为0.02μg/(cm^(2)·h),在低、中、高3个加标浓度下的回收率在93.26%~107.65%,相对标准偏差为1.03%~5.99%(n=7);采用石墨炉原子吸收光谱法测定的定量限为0.01μg/(cm^(2)·h),在低、中、高3个加标浓度下的回收率在82.65%~110.32%,相对标准偏差为1.08%~4.61%(n=7)。该方法前处理步骤简单,检测流程短,结果准确度高,适用于可放入婴幼儿和儿童口中的纺织品及其附件的检测。A test method for measuring the lead release in textiles and textile accessories by using artificial saliva as extraction medium was established,and the sample pretreatment conditions and instrument parameters were optimized.The results show that the quantitative limit of the method determined by inductively coupled plasma atomic emission spectrometry was 0.02μg/(cm^(2)·h),the recovery at low,medium and high spiked concentrations ranged from 93.26%to 107.65%,and the relative standard deviation was 1.03%~5.99%(n=7).The limit of quan-tification of the method determined by graphite furnace atomic absorption spectrometry was 0.01μg/(cm^(2)·h),the recoveries at three spiked concentrations of low,medium and high were 82.65%~110.32%,and the relative standard deviation was 1.08%~4.61%(n=7).This method has simple pretreatment steps,short detection process and high result accuracy,which is applicable to the detection of textiles and accessories,which may be put into the mouth of infants and children.
