| 摘 要： | 本文建立了氟硼酸根离子选择性电极测定沉积物中的硼。在建立本方法过程中,做了各种干扰条件实验,得到了满意的分析结果。实验中不用溴甲酚绿,效果很好,可延长电极寿命。实验证明,本法较比色法简单、快速、干扰少,而且不需大型仪器设备,可测定0.000x—0.x%的硼。

| Abstract: | This paper described a method of determination of boron in sediment by BF4 ion selective electrode. The procedure is more simple and rapid than colorimetric method. Some kinds of acidic medium as hydrofluoric, sulphuric and phosphoric acid etc. have been studied. The solution of this method can be 0.00X-0.X%B. About 100 samples of sediment from the North China plain have been determined using this method and satisfactory results have been obtained. |
