In this paper, a direct potentiometric method for determination of aluminium in soil usingthe fluoride ion-selective electrode was developed. The new technique has some advantages,such as simplicity, reliability and rapidity over the existing potentiometric methods. The exper-imental results of determining Al in soil with thls method are in good agreement with thoseobtained from atomic absorption spectrometric method.

本文提出用氟离子电极对土壤中铝作直接电位法测定。大大减少了以往的用终点电位滴定法测定土壤中铝含量的实验步骤与时间,并较大地提高了测定的准确度。方法是取一定量的土壤试液加入到pH为5,离子强度为1.0的缓冲溶液中,再加入一定量的F~-离子标液,让F~-与Al_(3+)络合稳定后,用氟离子电极测出溶液中的游离态F~-浓度,从而计算出Al~(3+)的总浓度。

An experimental method for direct determination of aluminium in soil -with fluoride ion-selective electrode was described. With this method the total concentration of Aluminium ( CA 1 ) from the concentration of F-(Cp- ) determined in soil sample solution could be obtained according to the proposed "F-, Al3+ ions relation table" . This method can also be used for the determination of aluminium in other samples.
