我们用中国科学院上海冶金研究所研制成功的四氟硼酸根离子选择电极,对铁钢中硼的测定进行了试验研究。实验结果表明,主量铁和大量的 Cr~(3+),Ni~(2+),Mn~(2+),Co~(2+),Ti~(4+),Al~(3+)等元素不干扰硼的测定,铌的干扰可用酒石酸掩蔽,试样溶解后,仅需15分钟左右就能完成一样品的分析。较一般化学法简单、快速,结果的准确度亦尚满意,本法 We used the tetrafluoroborate ion selective electrode developed by Shanghai Institute of Metallurgy, Chinese Academy of Sciences, to test the determination of boron in iron and steel. The experimental results show that the main iron and a large number of Cr3 +, Ni2 +, Mn2 +, Co2 +, Ti4 +, Al3 + ) And other elements do not interfere with the determination of boron, niobium interference tartaric acid masking, the sample is dissolved, only about 15 minutes to complete a sample analysis. This method is simpler and faster than the general chemical method, and the accuracy of the results is still satisfactory
