摘要
土壤在碱性条件下完全蒸馏,在酸性条件下与亚硝酸重氮化,再与盐酸萘乙二胺偶合,在波长545nm处测定中土壤中苯胺类化合物,方法检出限为0.15μg/g,加标回收率满足80%-110%质控范围,此方法用于测定土壤中苯胺类化合物可得到满意的结果。
Distilling completely under alkaline conditions, and diazotizing with nitrous acid under acidic conditions, and then with N-(1-naphthyl) ethylenediamine dihydrochloride coupling of aniline compounds in soil was measured at a wavelength of 545nm. The method detection limit is 0.15μg/g and recoveries meet the range of 80% to 110% quality control. This method is suitable for the determination of anilines in soil.
