A convenient chemical titration method to measure M(ii)/M(iii) ratios of layered double hydroxides
Abstract
The M(II)/M(III) ratio is an important structural feature of layered double hydroxides (LDHs). Here, we report a convenient chemical titration method to measure the M(II)/M(III) ratio of LDHs. The measured results have a relative standard deviation of less than 1.0%, and agree with the data measured by inductively coupled plasma (ICP) atomic emission spectroscopy very well.
