氧化锆是一种高温抗腐蚀的涂层材料,其纯度和铁等杂质影响其性质。因而对氧化锆的测定成为必要。锆的重量测定方法有好几种,并已有专著评论,各有优缺点。例如,认为用苦杏仁酸及其衍生物测定时有大量铁,铝,钛存在将给出不稳定结果等。因而对存在一些杂质元素的氧化锆的测定不甚理想。N-苯甲酰苯胲(简称BPHA)是铜铁试剂以来的一个
Zirconia is a high temperature corrosion-resistant coating material, its purity and impurities such as iron affect its nature. Therefore, the measurement of zirconia becomes necessary. There are several ways to determine the weight of zirconium, and monographs have been reviewed, each with its own advantages and disadvantages. For example, the presence of a large amount of iron, aluminum, and titanium in the determination of mandelic acid and its derivatives will give erratic results. Therefore, the determination of zirconium oxide with some impurity elements is not ideal. N-Benzoylbenzene (BPHA) is one of the copper and iron reagents since
