The adsorption process is one of the most important techniques of water and wastewater treatment technology. Therefore, there are many methods allowing to improve the effectiveness of these processes based mainly on the chemical modification of adsorbents. However, they are always associated with the necessity of introducing an additional wastes or sewage to the environment. That is why a purpose of the presented was to investigate an innovative and noninvasive adsorption supporting method based on the using of a static magnetic field. The results showed that in the adsorption process of equimolar copper, nickel, and cadmium mixture, a presence of the magnetic field may increase the effectiveness of the process, with respect to copper by more than 40% and a summary molar removal was increased about 11%. However, the effectiveness of the analyzed modification depends largely on the heavy metal equilibrium concentration, and when it increases, a beneficial effect of magnetic field significantly decreases. Nevertheless, due to the fact that heavy metal adsorption processes are very important part of environmental engineering technologies, it can be assumed that further work on magnetic modification of these processes can allow for a significant improvement of many water and wastewater purification plants.

吸附过程是水和废水处理技术中最重要的技术之一。因此，有许多方法可以提高这些过程的有效性，主要基于吸附剂的化学改性。然而，它们总是伴随着向环境中引入额外废物或污水的必要性。这就是为什么本文的目的是研究一种基于静磁场使用的创新且非侵入性的吸附支持方法。结果表明，在等摩尔铜、镍和镉混合物的吸附过程中，磁场的存在可能会提高该过程的有效性，相对于铜提高超过40%，总摩尔去除率提高约11%。然而，所分析改性的有效性在很大程度上取决于重金属平衡浓度，当浓度增加时，磁场的有益效果会显著降低。尽管如此，由于重金属吸附过程是环境工程技术的非常重要的一部分，可以假设对这些过程进行磁性改性的进一步工作可以使许多水和废水净化厂得到显著改进。图形摘要。
