Abstract

The present invention discloses a preparation method for and the use of a lithium silicate-based adsorbent. The method comprises: mixing and stirring butyl methacrylate, an acid and an organic solvent to obtain a first solution; adding lithium silicate, an initiator and N,N′-methylenebisacrylamide into the first solution, and heating and stirring same for a reaction to obtain a second solution; subjecting the second solution to low-temperature dehydration, cooling and drying to obtain a lithium silicate-based polymer; mixing the lithium silicate-based polymer with a third solution; and subjecting same to low-temperature carbonization under anoxic conditions, so as to obtain the lithium silicate-based adsorbent, wherein the third solution is obtained by mixing cotton fibers, tartaric acid, carboxymethylcellulose and water.
