| 中文摘要 |
| 比较了几种用于沉积物中丁基锡化合物的FPD-气相色谱测定方法。其中适于沉积物的方法是在冰醋酸中,以苯-己烷(2:1)混合溶液提取沉积物中丁基锡化物,然后用NaBH4将其转变为挥发性的氢化丁基锡,用带有火焰光度检测器的气相色谱仪进行检测,本法测定丁基锡化物的最低检出限为4-10ng/g土。 |
| 英文摘要 |
| A method is described for determination of butyltin species in sediments. The butyltin species were extracted from sediments with a mixed benzenehexane (2:1) solvent after a sonication in acetic acid, then converted into volatile butyltin hydrides by using a solution of sodium tetrahydroborate.Butyltin hydrides were measured by gas chromatography with flame photometric detector.The detection limits were 4-10ng tin per gram of sediment sample. |
