An energy dispersive X-ray fluorescence method for trace element analysis in plants (leaves and roots) is presented. The method is characterized by the use of a secondary target excitation, thin specimen, and microwave acid digestion. The accuracy is about 10% and the sensitivity is in the range 10-50 ng/cm2. The analysis time (from dry sample to concentration data) is about 4 x 10(3) s. The effects of Cr in sewage sludge on barley seedling growth is presented.
提出了一种用于植物（叶片和根系）微量元素分析的能量色散X射线荧光法。该方法的特点是使用二次靶激发、薄样品和微波酸消解。准确度约为10%，灵敏度在10 - 50 ng/cm²范围内。分析时间（从干燥样品到浓度数据）约为4×10³ s。还介绍了污水污泥中铬对大麦幼苗生长的影响。
