近年来，预测污染土壤，特别是重金属污染土壤的净化效率已成为一个重要的研究课题。未能正确预测效率的方法导致了经济损失和处罚。本文介绍了一种除了传统的土壤重金属污染的表征方法，提高了基本决策的质量。该方法是基于磁分离使用Frantz等动力分离器（FIS）的这项研究。FIS分离出含有重金属的土壤颗粒，以便更详细地研究与土壤清洁相关的这些颗粒。测试了四种受污染的土壤，例如，对土壤清洁工业来说是个问题的土壤。实验表明，每一种土壤都有其独特的磁性特征，可以看作是一种指纹。两种土壤的密度测定结果表明，密度接近中、高质量分离的石英密度。
In recent years forecasting soil cleaning efficiencies of polluted soil, especially those contaminated with heavy metals, has become an important issue. Failure of the methods to predict the right efficiency has resulted in financial losses and penalties. This article describes an addition to the traditional characterization methods for soils contaminated by heavy metals, improving the quality of the basic decisions to be made. The method is based on magnetic separation using a Frantz Isodynamic Separator (FIS) for this study. The FIS isolates soil particles containing heavy metals so that these particles, which are relevant for soil cleaning, can be studied in more detail. Four contaminated soils were tested, for example, soils that were a problem for the soil-cleaning industry. The experiments indicate that each soil has its own magnetic properties that should be regarded as a fingerprint. Density measurements of two soils show that densities approach the quartz density separated at moderate and high ma...
