摘要
为了解曲靖市麒麟地区饮用水质量和进行水处理提供理论依据,对该地区饮用水进行氟含量测定分析.方法采用离子选择电极法测定曲靖市麒麟区8个地方的饮用水的含氟量.结果表明,曲靖麒麟地区的饮用水氟含量在0.0387mg/L到0.2122mg/L范围.不同地方之间氟含量有一定差异,但均低于国家规定标准（1.0mg/L）;余家屯和南园村地区饮用水氟含量小于0.05mg/L,甚至有严重低氟现象.线性范围为1×10-6-1×10-2mol/L,检出限为0.015mg/L,RSD在1.53％-3.6％之间,回收率为93％～97％之间.结果表明该方法简单快速、选择性好、准确度高,可作为饮用水及其他水质中氟含量的测定法.
The water quality in Qilin district of Qujing city was investigated, the theoretical basis for water treatment was provided and the fluorine in drinking water was determined through selective electrode method in 8 areas in Qilin district of Qujing city. The results showed that the fluoride contents ranged from 0. 0387mg/L to 0. 2122mg/L, varying in different areas below the national standard （ 1.0 mg/L）. The flu- oride contents in Yujiatun and south village were lower than 0. 05mg/L. There was severe low fluorine phe- nomenon. The linear was 1× 10 -6 - 1 × 10 -2mol/L and the detection limit was 0. 015mg/L. The relation standard of deviation （RSD） wasl. 53% - 3.6% and recovery rates were 93% -97%. The result indicated that this method was simple and quick, high in selectivity and accuracy and could be used in the determina- tion of fluoride content of drinking water and other water.
