尿液中尼古丁含量的测定

Determination of Nicotine in Urine

研究了分光光度法测定尼古丁的方法,测定下限为0.81μg/ml,线性回归方程Abs=0.05976+0.00108x(mL),相关系数r=0.9996;尿液中的加标回收率在80.4％～138％,RSD在0.12％～3.88％(n=4)。

method of determination nicotine of in emicition by spectrophometry was studied, the detection limit is 0.81μg/mL and the linear regression is Abs= 0. 05976 ＋ 0. 00108x（mL）. The recovery rate was 80.4% to 138.0 % and the relative standard deviation is 0.12 % to 3.88 %.
