摘要
本文采用双波长二阶导数光谱法直接测定盐酸苯海拉明糖浆中盐酸苯海拉明的含量,其浓度在2.5～25.0μg/ml 范围内呈较好的线性关系,标准曲线方程为Δ((dαA)/(dλ~2))=0.00658c-0.00095,r=0.9999。在三种不同浓度下的回收率(n=3)分别为100.13%,99.56%,100.33%;CV%为0.11%,0.84%、0.64%。
Derict determination of dipheuhydramine hydrochloride in syrup by double-wavelength second derivalive spectropho-to metry is reported here.Good linearity was obtained in the concentration of 2.5～25.0μg/ml,the correlation coefficient was0.9999.Recovery(n=3)and ov% obtained at three different concentration levels were 100.1%,99.6%,100.3% and0.11%,0.84%,0.64% respectively.
