Were carried out adsorption studies in a continuous system subjected to external magnetic fields of three different intensities; non intensity (NI), low intensity (LI) and high intensity (HI), generated from permanent magnets, in order to evaluate the removal of three different heavy metals in ionic state (Cd²⁺, Pb²⁺ and Zn²⁺). The design of magnetic field application systems is supported by finite element computational simulations. The results show that the application of an external magnetic field improves the adsorbate retention proportionally to the intensity of the applied magnetic field, intensifying said process compared to a system without the application of a magnetic field, increasing the maximum adsorption capacity. The results show an increase in adsorption capacity of 16.02% for the removal of Cd²⁺ and 6.81% for Zn²⁺; however, the removal of Pb²⁺ had a small difference of 2.41%, which is attributed to the subtle differences in the physicochemical and magnetic characteristics of this adsorbate and the others such as hydrated ion radius and magnetic susceptibility. Additionally, a proposal of the mathematical model that could describe the phenomenon based on the variables shown here is made.

在受到三种不同强度的外部磁场的连续系统中进行吸附研究；由永磁体产生的非强度 (NI)、低强度 (LI) 和高强度 (HI)，以评估离子状态下三种不同重金属（Cd ²⁺、Pb ²⁺和 Zn ^{2+ ）的去除情况}）。有限元计算模拟支持磁场应用系统的设计。结果表明，与不施加磁场的系统相比，施加外部磁场可提高吸附质保留与施加磁场强度成比例，从而增强了所述过程，从而增加了最大吸附容量。^{结果表明，去除Cd 2+}的吸附量增加了16.02%，去除了Zn ²⁺的吸附量增加了6.81% ；然而，去除 Pb ²⁺有 2.41% 的微小差异，这归因于该吸附物的物理化学和磁性特征与其他水合离子半径和磁化率等细微差异。此外，提出了可以根据此处显示的变量描述现象的数学模型。
