过去,植株中Si的测定很费力也很困难,在植物分析以外的某些研究领域里,用HF消煮样品,然后用硼酸处理,除去过多的HF。在本研究中,把这一方法用于植物样品,但在用HF消煮之前,植物样品先进行干灰化,经适当的稀释后Si可以用比色法测定。该方法快速、准确。 In the past, the determination of Si in plants has been laborious and difficult. In some fields of research other than plant analysis, samples were digested with HF and then treated with boric acid to remove excess HF. In this study, this method was applied to plant samples, but prior to HF digestion, the plant samples were first dry-ground, and after appropriate dilution, Si could be determined by colorimetry. The method is fast and accurate.
