| 摘 要： | 地质样品中氟、氯、硫的测定是十分重要的,这是由于氟是矿化作用的可靠标志,而且氟、氯、硫也被认为是不同类型沉积矿物的指示元素。地质样品中氟的测定方法通常采用氟离子选择电极法(别婉琳等,1980),氯的测定一般采用碱熔-硫氰酸汞比色法或碱熔硝酸汞滴定法等。

| Abstract: | The method of simultaneous determination of fluorine,chlorine and sulfur in geological samples with an ion chromatographic instrument is described.The samples were fused with peroxide sodium at 530℃ for 15 minutes. The products were digested by hot water. The matrix elements in the solution were separated by H-type cation exchange resin. This method is simple and rapid.The United States geological survey standard MAG-1 was analysed repeatedly ten times. The relative standard deviations were 8%,4%,4%,for F,Cl,and S,respectively. |
