【摘要】 将环境植物样品在４００─５００℃灰化，用硝酸、氢氟酸和高氯酸分解，用盐酸（１＋１）提取，控制２％─３％的盐酸介质，用火焰原子吸收分光光度法测定环境植物样品中的微量铜、铅、锌、铁、锰。该方法简单、快速、可靠。对环境植物标准样品的测定结果理想。更多还原

【Abstract】 The analytical method of copper,lead,zinc,iron and manganese in environmental plantsamples has been studied in this article. The environmental plant samples are ashed at thetemperature of 400─500℃and then decomposed by nitric,hydrofluoric and perchloric acid.Copper,lead,zinc,iron and manganese in the sample solution are then determined respective-ly by flame atomic absorption spectrophotometry.The method is simple,rapid and reliable. The method has been applied to the determina-tion of standard reference samples of environmental plant with very satisfactory results.更多还原
