空气中氟化物的采样方法很多,归纳起来可分为两类:一类是液体采样法,它通常使用冲击式吸收管,内装吸收液——水或碱溶液。据Farrah指出:水比碱溶液更好,采样效率可达97—100％。另一类是滤纸采样法,它分别使用玻璃纤维滤纸浸渍氢氧化钠溶液、醋酸纤维滤纸浸渍甲酸钠溶液、纸或薄膜浸渍碳酸钠溶液。据Elfers与Decker报道,采样效率可达100％。此外,该法在应用氟离子电极法时的
There are many ways of sampling fluoride in the air, which can be divided into two categories: one is the liquid sampling method, which usually uses an impact absorber and contains absorption liquid - water or alkali solution. According to Farrah, the water is better than the alkaline solution and the sampling efficiency can reach 97-100%. The other is the filter paper sampling method, which uses glass fiber filter paper impregnated sodium hydroxide solution, acetate fiber filter paper impregnated sodium formate solution, paper or film impregnated with sodium carbonate solution. According to Elfers and Decker reports, sampling efficiency up to 100%. In addition, the method in the application of fluoride ion electrode method
