| 摘 要： | 在微酸性溶液中,加入一定过量的氟化钾沉淀剂,使铝与它定量生成铝氟酸钾沉淀。用氟离子选择电极测定过量的F~-量,间接计算出试样中铝的舍量。此法简便、快速、干扰少、结果与常规的络合滴定法相比无显著性差异。

| Abstract: | In slighly acidic solution and known quantity of exceeding potassium fluoride precipitating agent, aluminium ions from potassium fluoroaluminate precipitate and the exceeding fluorideions can be determined by fluoride selective electrode direct potentiometry. The fuantity of aluminium oxide is calculated, this method is simple, qast and almost no interference and its result is reliable. |
