| 摘 要： | 本文建立了一套系统测定海洋环境中氟的方法。该法在沉积物的分析中用控制溶液的pH值来排除干扰离子,在海水和间隙水中对氟的测定用两次加入法及使用微型计算机,从而避免了斜率误差与传统方法的烦琐计算。本法简便快速,取样量少,并具有良好的精确度,是海洋环境监测和氟的地球化学研究的有效手段。

| Abstract: | The article set up a method which determines the concentrations of fluorine in marion environment quickly and accurately. The method controlls the pH value of solution to remove the disturbing ions for the determination of fluorine concentration in sediments, and uses two time added method and a small procedure ( with PC-1500) for the analyses of sea water and pore water, which effectively avoid the error in slope and the complicated calculation in conventional methods. The method is simple and only requires 2- 5 ml sample in the determination of pore water. As a result, it is an effective means for the supervision of marine environment and the study of marine geochemistry of fluorine. |
