摘要
综述了近10年来对饮水、食品、牙膏及化妆品等样品中氟化物的测定方法及其适用性。离子选择电极法简便、快速且仪器价格低廉,可测定水中氟化物低达5.26×10-6mol/L。氟试剂分光光度法引用乙酰丙酮为掩蔽剂,提高了灵敏度、精密度和准确度。离子色谱法可同时测定尿中F-和I-,且F-在100～1500μg/L之问呈线性关系。
Abstract This article presented a review on applicability of methods for the determination of fluoride in samples of drinking water, food, toothpaste and cosmetics in the past 10 years. Use of the ion selective electrode provided a simple and rapid method for fluoride determination, the detectable levels for fluoride as low as 5.26X10'6 mol/L could be measured. The modified fluororeagent spectrophotometric method by adding acetylacetone as a masking agent improved the sensitivity, precision and accuracy of the method. Both fluoride and iodide ions in urine could be determined simultaneously with ion chromatography, which showed a linear relationship at fluoride levels between 100 1 500 p.g/L.
