| Abstract: |
| Migration of elements in plastics, textiles and paint coatings, which are commonly used in toys, to the simulated gastric fluid, acidic perspiration , alkaline perspiration and saliva are studied by ICP-AES. The samples were soaked in the simulated body fluids and the amount of elements that migrated from the samples to the fluids were determined by analyzing the liquid extraction by ICP-AES. The elements that were determined included Al,Sb,As,Ba,B,Cd,Cr,Co,Cu,Pb,Mn,Hg,Ni,Se,Sr,Sn,and Zn, which of contents are all restricted by the New?European?Union?Toy?Safety Directive. Influence of different oscillation frequencies on metallic element migration content detection during the sample pretreatment process were studied. The results showed that simulated gastric fluid has the biggest metal dissolution ability, while the simulated perspiration has the smallest metal dissolution ability. During the sample extraction process, when the oscillation frequencies of constant temperature water bath are between 80~160 r/min, the RSDs of tested dissolution quantity of the certain migrate elements are below 10%. |
