The kinetic characteristics of lead ion (Pb²⁺) sorption using solid extractants based on aluminum oxide (Al₂O₃) were investigated. Analysis of the experimental data revealed that the sorption process follows a pseudo-second-order kinetic model, indicating that it proceeds via a chemical sorption (chemisorption) mechanism.
