二氧化钛含量通过比较测试的涂料样品和标准液中钛和溴峰的强度检测出!计算结果需要考虑涂料中不同的不挥发物。
【感觉怪怪的,楼主是不是没有把问题描述完整】

原文如下
Paint containing a known amount of titanium dioxide is
used as the reference standard. A solution of tetraethylammonium
bromide in 2-ethoxyethanol is added to the standard paint
and to each paint being analyzed. Drawdown films of the
standard and test paint are made on thin plastic sheets. The
intensities of key X-ray fluorescence peaks of titanium and
bromine are measured. The titanium dioxide content is determined
by comparing the ratio of the intensities of titanium and
bromine peaks in the test paint and the standard. Differences in
the nonvolatile content of the paints are taken into account in
the calculation of results.
是ATSM D4764-01标准的原理概述,我不是很清楚,水平有限。能帮我看看吗?
谢谢!
