摘要
目的:研究镉在金银花中的分布规律情况。方法:样品采用高压微波消解,原子吸收石墨炉法检测。结果:镉在金银花中的含量分布规律为:茎>根>花>叶>生长土壤,多年生金银花中镉含量更高。结论:金银花及其根茎叶对土壤中的镉有一定的富集作用,且镉在金银花中的分布规律与其它一些报道的植物有差异,具体原因有待进一步研究。
Objective:To investigate cadmium distribution in flowers,leaves,stems,roots and corresponding soil of honeysuckle.Methods: The soil sample was digested with the mixture of hydrochloric acid and nitric acid(3∶ 1),plant sample was digested with nitric acid,and then detected by GF-AAS.Results: Distribution of cadmium contents in honeysuckle and corresponding soil was stems roots flowersleaves soil,and the contents of cadmium in perennial honeysuckle were higher.Conclusion: Honeysuckle has enrichment ability for Cd from soil,but its distribution law differs from other reported plants.The reasons needs further research.
