Abstract

The paper presents the results of studies of the sorption properties of layered double hydroxide of the composition Mg₄Al₂(OH)₁₂CO₃⋅3H₂O, obtained by the solid-phase interaction method, with respect to the \({\text{PO}}_{4}^{{3 - }}\) ion. It is found that the sorption process is most adequately described by the Langmuir monomolecular adsorption equation, and its kinetics is described by a pseudo-first-order equation. The activation energy of the process is determined, based on which is concluded that the process occurs in the diffusion region.

层状双层氢氧化铝镁吸附磷酸离子的动力学研究

采用固相相互作用法研究了Mg4Al2(OH)12CO3⋅3H2O层状双氢氧化物对\({\text{PO}}_{4}^{{3 - }}\)离子的吸附性能。发现吸附过程用Langmuir单分子吸附方程最能描述，其动力学用拟一阶方程描述。测定了该过程的活化能，据此得出该过程发生在扩散区。
