摘要
本文采用氟离子选择电极法测定水中微量氟。对几种总离子强度缓冲液(TISAB)的检出限进行了测定和比较,鉴于在测定过程中电极斜率漂移的情况,选用二次标准加入法,借助于SHARP-PC-1500计算机处理实验数据;对北京地区饮用水中的微量氟进行了分析测定,较全面地调查了北京地区水氟状况井予以评价。
Quantative determination of trace amount of fluoride by using fluoride-ion selective electrode was reported. The .detection limit of some kinds of TISAB solutions were determined and compared. Because of the electrode slopes during the determination process we e unstable, secondary standard addition was adopted. The experimental data was treated by using a pocket computer PC-1500 program. The fluoride contents in drinking water in Beijing district were surveyed rather throughly and were assessed.
