有关二氧化钛含量的测定,迄今报道的不多,以往测定二氧化钛的含量,首先是用锌汞剂将高价钛还原为低价钛。汞一般在低温状况下,会逸出汞蒸气,不利于环境保护,有害身体健康。就方法而论,操作繁琐,分析的准确度差。因此,我们针对上述问题进行了新的方法试验,已获得成效。现介绍如下。 Titanium dioxide content of the determination so far reported little, the previous determination of the content of titanium dioxide, the first is the use of zinc amalgam to high-priced titanium reduced to low-cost titanium. Mercury generally escapes mercury vapor at low temperatures, adversely affecting the environment and harmful to health. In terms of methodology, the operation is cumbersome and the accuracy of the analysis is poor. Therefore, we have conducted a new method test on the above issues and have achieved results. Now introduced as follows.
