The process of adsorption from water solutions containing a ternary system of Cu (II), Zn (II), and Ni (II) ions onto buckwheat hulls as a biosorbent was considered. The sorption capacity for buckwheat hulls was determined in sorption equilibrium batch experiments. The sorption kinetics equation corresponding to the mechanism of metal ions with the adsorbent was assumed. A new method for modeling sorption in a packed column was presented. A system of partial differential equations describing the mass balance, due to the assumption of a properly defined variable, was transformed into a system of ordinary nonlinear equations, which enables the identification of object parameters. The sorption capacity of the sorbent, sorption isotherms, and kinetics equations were used in dynamics modeling.
研究了荞麦皮作为生物吸附剂从含有 Cu（II）、Zn（II）和 Ni（II）离子的三元体系水溶液中吸附的过程。在吸附平衡批量实验中确定了荞麦皮的吸附容量。假设了与吸附剂相互作用的金属离子的吸附动力学方程。提出了一种用于填充柱吸附建模的新方法。通过假设适当定义的变量，将描述质量平衡的偏微分方程组转换为常非线性方程组，从而能够识别目标参数。在动力学建模中使用了吸附剂的吸附容量、吸附等温线和动力学方程。
