A small volume of fluoride solution was added into soil solution, then the fluorideelectrode procedure Was used to characterize inorganic monomeric aluminum species in the solution.
向土壤溶液中加入一已知量的氟标准溶液，再用氟离子电极测定和区分溶液中无机单核铝的形态。

We tested the quantity of fluoride in tea leaves by separately using fluorinion selective electrode and the ion chromatographys.
我们分别采用离子色谱法和氟离子选择电极法对茶叶中氟化物的含量进行测定。
