建立了萃取／硝化／石墨炉原子吸收法分析海水中三丁基锡的方法，筛选了最佳的萃取条件、基改剂及石墨炉参数。本方法检出限为０１６μｇ／Ｌ；相对标准偏差最高不超过４％；回收率为９４％～１０５％。
A method for the extraction of tributyltin in seawater by extraction / nitrification / graphite furnace atomic absorption spectrometry was established. The optimal extraction conditions, base modifiers and graphite furnace parameters were screened. The detection limit of this method was 0.16μg / L; the relative standard deviation was no more than 4%; the recovery was 94% -105%.
