如何满足金属和合金部门的需要,研究出一种日常使用的、简单而可靠的、测定高(低)合金钢中微量硼的方法,是化学实验室长期存在的问题。测硼的方法很多,只是都有达样或那样的缺点,总不能令人满意。例如应用最广的亚甲基兰-氟硼酸盐法,再现性较差,试剂空白高,要求酸度条件苛刻,形成络合物需要有高浓度 How to meet the needs of the metal and alloy sectors and to develop a simple, reliable and routine method for the determination of trace boron in high (low) alloy steels is a longstanding problem in chemical laboratories. There are many ways to measure boron, but there are always the same or the same shortcomings, which can not always be satisfactory. For example, the most widely used methylene blue - fluoroborate method, poor reproducibility, high reagent blank, requiring harsh acid conditions, the formation of complexes need to have a high concentration
