氟是广泛分布于大气、土壤,水源和生物体的元素,由于摄取氟的多少对人体健康有关,前人对谷物、疏菜、饮用水、大气和土壤做了大量分析研究,但至今尚未见到有关植物性中药材含氟量的报道,本文作者用ISE法对我院第一附院中药房常用的255种植物性中药材测定氟含量简报如下: 一、仪器和试剂氟电极:(817—02)苏州标准计量局电位计:PHS—2型精密酸度计上海第二分析仪器厂离子强度缓冲调节剂:3M醋酸钠水溶液与0.75M柠檬酸三钠水溶液等量混合。
Fluorine is an element widely distributed in the atmosphere, soil, water, and organisms. Since the intake of fluorine is related to human health, predecessors have done a lot of research on cereals, vegetables, drinking water, the atmosphere, and soil, but they have not seen it yet. To report on the content of fluorine in botanical Chinese herbal medicines, the authors used the ISE method to report the fluorine content of the 255 kinds of botanical herbs commonly used in the First Affiliated Hospital of the Chinese Academy of Sciences, as follows: I. Instruments and reagents Fluoroelectrodes: (817) — 02) Suzhou Standards and Metrology Bureau Potentiometer: PHS-2 Precision Acidometer Shanghai No. 2 Analytical Instrument Factory Ionic Strength Buffer Conditioner: 3M sodium acetate solution and 0.75M trisodium citrate aqueous solution are mixed in equal amounts.
