自从Fran和Ross用氟化镧单晶电极测定氟以来,氟电极得到很广范的应用。目前在血、尿、生物样品、水、空气、植物及矿石分析等各方面氟的测定中都应用了氟电极~((2))～((5))。它具有操作简便、准确、快速、干扰因素少等优点。在生物样品氟含量测定中样品的处理多采用燃烧法,但骨灰化后,骨盐不能燃烧,给电极法测定带来一定的困难,为此我们采用了酸溶法测定骨中氟含量,现报告如下: 仪器与试剂 一、仪器: 1、氟电极:CSB-F-1型,长沙半导体材料厂出品; 2、甘汞电极:232型,上海电光仪器厂出品;
Since Fran and Ross with fluoride fluoride single-electrode determination of fluoride, the fluorine electrode has been widely used. At present, fluorine electrodes ~ ((2)) ~ ((5)) are all used in the determination of fluorine in blood, urine, biological samples, water, air, plants and ore analysis. It is easy to operate, accurate, fast, less interference and so on. In the determination of biological samples fluorine content in the sample processing more combustion method, but after the ashes, bone salt can not burn, to the electrode method to determine the degree of certain difficulties, for which we used the acid solution method for the determination of bone fluorine content, and now The report is as follows: Instruments and reagents First, the instrument: 1, fluorine electrode: CSB-F-1 type, produced by Changsha Semiconductor Materials Factory; 2, calomel electrode: 232, Shanghai Light Instrument Factory produced;
