建立了水样中苯基锡化合物（二苯基锡、三苯基锡和四苯基锡）的高效液相色谱-电感耦合等离子体质谱（HPLC-ICP-MS）的分析方法。水样采用正己烷（含0．01％环庚三烯酚酮）液液萃取，VARIAN Pursuit 5μ-C18反相色谱柱分离，ICP-MS测定。流动相为 V甲醇V乙酸（10％，用三乙胺调 pH为3．0）＝8515。3种化合物在0．5～40μg·L-1范围内均呈良好的线性关系，线性相关系数r＞0．999；仪器检测限分别为0．16，0．11和0．18μg·L-1；加标回收率在85．3％～109％之间；相对标准偏差＜8％。方法应用于实际水样中3种苯基锡化合物的分析，结果满意。

In this study,a sensitive and accurate method for simultaneous determination of three phenyl-tin compounds (diphenyltin,triphenyltin and tetraphenyltin)in water samples with HPLC-ICP-MS was devel-oped.The samples were treated by liquid-liquid extraction with n-hexane(containing 0.01 % tropolone), then were separated and detected by HPLC-ICP-MS.VARIAN Pursuit 5μ-C18 was selected by a separate column,the composition of mobile phase was optimized as VCH3OH:Vacetic acid(10%,pH was adjusted to 3.0 with triethylamine)=8515.The linear calibration curves were conducted in the 0.5μg·L~40μg·L-1 concentration range and the coefficients were found to be all over 0.999.The instrument detection limits of diphenyltin (DPhT),triphenyltin (TPhT)and tetraphenyltin (TePhT)were 0.16,0.11 and 0.18μg· L-1 ,respectively.The average recoveries were in the range of 85.3%~109% with the R.S.D.<8%.This method was applied to the simultaneous determination of DPhT,TPhT and TePhT in Poyang lake samples with expected results.
