摘要

This review primarily aims to systematically examine recent advances in heavy metal ion immobilization using magnesium phosphate cement (MPC) and Portland cement through a comprehensive analysis of literature published between 2000 and 2023. The article critically evaluates the solidification/stabilization (S/S) behavior of MPC-based systems for heavy metal containment, with particular emphasis on the fundamental mechanisms governing metal ion fixation. By employing systematic bibliometric analysis, we identify and discuss the principal challenges currently limiting technological implementation, including optimization of solidification efficiency and enhancement of mechanical performance in contaminated matrices. Furthermore, this synthesis highlights emerging research directions and potential engineering applications, proposing novel methodological frameworks for advancing S/S technology development. The critical insights presented herein provide both theoretical guidance for optimizing heavy metal immobilization strategies and practical references for engineering applications of MPC-based stabilization systems.
