摘要
以十六烷基三辛基氟硼酸铵为电活性物质,制备了BF_4^-离子选择性电极。在Na_2SO_4底液中,电极对BF_4^-离子有很好的电位响应。实验考察了共存离子的干扰情况及测定的最佳酸度范围。电极用于仲钨酸铵中硼的测定,将仲钨酸铵中的硼转化为BF_4^-,用标准加入法测定其中硼的含量,结果满意。
A PVC membrane BF4- ion selective electrode based on cetyl trioctyl ammonium iodide was prepared. In 0. 01M sodium sulfate medium, the electrode showed good potentiometric performance for BF4-. The effect of acidity and interference on the electrode response were studied. The electrode was used to the determination of boron in ammonium tungstate.
