Determination of Trace Migratory Organo-Tin in Toys by HPLC-ICP-MS
摘要
Abstract
A method for determinating trace migratory organo-tin in toys by high performance liquid chromatography-inductively coupled plasma mass spectrometry (HPLOICP-MS) was developed. The organo-tin species dibutyltin(DBT) , triphenyltin(TPhT) , tributyltin (TBT) and dioctyltin(DOT) were separated on Waters Acquity UPLC HSS T3 analysis column using the mobile phase of V(acetonitrile) : V(water) : V(acetic acid) = 65 : 23:12, 0. 1% triethylamine with pH 3. 0. This method is quickly and high sensitivity. The detection limits are 0. 08, 0. 24, 0. 14 and 0. 65 μg/L for DBT, TPhT, TBT and DOT with injection volume of 50μL. The recoveries are 80. 7%-96. 3% and 83. 5%-100. 4% for the spiked levels of 5 and 50 μg/L, and the RSDs are less than 4. 7%, which meet the determination requirements. This method has been used to determine migratory organo-tin in accessible parts of toys, including coating, plastic, wood and textile.关键词
