摘要
文中采用GC-MS仪器测定方法对海水中六种不同形态有机锡化合物进行分析。在确定的GC-MS测定方法基础上得到SPE条件优化:选择NH4DDC鳌合剂,用5%的甲醇为携带剂,流速1.5ml/min,萃取温度45℃,萃取压力300bar,萃取时间为15min。
The article analyzed the GC-MS determination of the instrument in six different forms of water organotin compounds for analysis. Choosing NH4DDC as chelating agent,5%methanol was added and the Flow rate was 1.SmlJminoexlraction temperature 45 ℃ and lhe procednres for extraction of organotins in seawater were at 300mbr withlSmin.
