| Abstract: | As a novel gelling material based on aluminosilicate inorganic polymer,alkali-activated gelling material has been widely used in the field of solidifying and stabilizing toxic heavy metal ions for its special hydration mechanism and products.The reaction products,structural properties and reaction mechanism of alkali-activated gelling materials were described.The way of alkali-activated gelling materials for solidification and stabilization of heavy metals such as arsenic,mercury,cadmium,lead,zinc and compound were summarized.The study indicates that so far detailed classification of alkali activated gelling materials has not been conducted yet,and a preferable theoretical system for studying the mechanisms,particularly chemical mechanism for solidification and stabilization of heavy metal ions by alkali-activated gelling materials have not been established either.Therefore,it is necessary to undertake further studies on the analysis and integration,application development,solidification mechanism and preparation technology of raw materials. |
