【摘要】 样品采用湿法消解,以邻菲罗啉做显色剂,采用分光光度法测定中草药菊花、枸杞、决明子中碘的含量,检测波长为512 nm,吸收度与浓度之间呈良好线性方程(r=0.9962),方法简单,操作方便可行。更多还原

【Abstract】 The samples were pretreatments by wet digestion,Phenanthroline as Reagent,trace element iodin in the Chinese Traditional medicine o f Chrysanthemum,Chinese wolfberry and Cassia Seed weredeterminated.512nm was selected optimal wavelength,In the best conditions,the absorbance and concentration showed good linearity(r=0.9962),The method is simple and quick.更多还原
