纺织品重金属含量检测方法研究
Study on detection methods of heavy metal content in textiles
摘要
Abstract
In order to solve the problems of insufficient detection accuracy,large differences in operation efficiency,and unclear applicability of different methods for heavy metal residues in textiles,four common types of textiles including cotton,linen,polyester and polyamide were taken as research objects,and five typical toxic heavy metals such as lead(Pb),cadmium(Cd),chromium(Cr),arsenic(As)and mercury(Hg)were selected.Empirical tests were carried out by three mainstream detection methods:atomic absorption spectrophotometry(AAS),inductively coupled plasma optical emission spectrometry(ICP-OES)and inductively coupled plasma mass spectrometry(ICP-MS).The sample pretreatment conditions were optimized,and the detection limit,precision,recovery rate and operation cost of the three methods were compared.The results show that ICP-MS method has the lowest detection limit(0.001-0.005 mg/kg),with the recovery rate ranging from 95.3%to 103.7%and the relative standard deviation(SRSD)≤2.1%,which is suitable for accurate detection of low-content heavy metals.AAS method is simple in operation and low in cost,with the recovery rate ranging from 89.5%to 97.2%and SRSD≤3.8%,which is suitable for routine batch sample detection.ICP-OES method features high efficiency in simultaneous multi-element detection,with the recovery rate ranging from 92.1%to 101.5%and SRSD≤2.8%.关键词
