【摘要】 <正> 测定水中痕量氟离子有多种方法,常用的分光光度法不但配制络合显色剂比较麻烦,而且一般的分光光度计不够灵敏,难以得到准确结果。本文应用国产201型氟离子选择电极,以802型单液接甘汞电极为参比电极,和 WL—15型微处理离子计配套使用,可以直接得出水样中所含氟离子浓度。与由标准曲线法所得的结果一致,一更多还原

【Abstract】 Fluoride Was determined with use of F^- Ion—selective.ele- ctrde Without prior treatment of the sample.Interference by Common ions may be musked or elimimated.4.21×10^-7mol L^-1 （8ppb） of F^- Could be determined with a coeff,of variation of 0.20%.Results agreed well with Those obtained by spoctrophotometry.This procedure for.fluoride determination described in this paper there is sensitixe,simple and reliable.更多还原
