本文介绍一种较经济的植物样品多元素批量分析的方法。样品经湿消化后,用原子吸收法分析8种元素。 材料与方法:材料用紫花苜蓿,其叶片在85℃下于真空干燥箱中干燥过夜,研细,通过1毫米筛孔。以4分法或2分法留20克叶样。每批消化5个试样(每样重复一次,加上空白,共12个)。准确称取于105℃下干燥过夜的叶样4克,放入长颈烧瓶中,加 This article describes a more economical method of multi-element batch analysis of plant samples. After wet digestion, the eight elements were analyzed by atomic absorption. Materials and Methods: The material used alfalfa, its leaves at 85 ℃ in a vacuum oven dried overnight, fine grinding, through 1 mm sieve. To 4 points or 2 points leave 20 grams leaves sample. Each batch of 5 samples digested (each repeat, plus a blank, a total of 12). Accurately weighed in 105 ℃ dried overnight leaves like 4 grams, into the long-necked flask, plus
