摘要
研究滤材对元素活动态测定结果及测定精密度的影响 ,综合考虑元素活动态测量结果的真实性以及土壤胶体的性质等因素 ,确定了 2 μm孔径的滤膜是用于活动态测量的较佳滤材 ,本研究对活动态测量方法的规范化、标准化具有重要意义。应用试验表明所选滤材适用于活动态测量。
The effects of filtering with different filters on analytical results and precisions of MOMEO elements have been studied in this paper. In view of the authenticity of the measured results of MOMEO elements and the properties of soil colloid, the 2 μm pore diameter membrane is determined as the optimal filter employed in MOMEO survey. It is of great significance to the normalization of MOMEO survey method. The application test shows that the 2 μm pore diameter membrane can be effectively used in MOMEO survey.
