摘要
盐酸异丙肾上腺素在伯瑞坦-罗比森缓冲溶液(pH=6.80)介质中有很强的荧光。其最大激发波长和发射波长为287nm和622nm。荧光强度与纯盐酸异丙肾上腺素浓度在0.1—2.3mg/L范围内呈线性关系。回归方程F=351.91C(mg/L)+139.02,r=0.9995,检出限为0.0087mg/L。测定注射用针剂中盐酸异丙肾上腺素的含量,方法简单,快捷,灵敏度高,结果令人满意。
In the medium of buffer solution （pH=6.80）, isoprenalinum has strong characteristics at excitation wavelength λex=287nm and emission wavelength λem=622nm. The linear range of concentration of isoprenalinum with intensity is of 0.1-2.3mg/L with the equation of F=351.91C （mg/L）＋139.02, r= 0.9995. The detection limit is 0.0087mg/L. The method is easy, repaid, sensitive and was applied to the determination of isoprenalinum in medicament with satisfactory results.
