The invention discloses a method for recovering gold from a thiosulfate solution, and belongs to the field of hydrometallurgy and precious metal recovery. According to the method, silica gel serves asa raw material, through a chemical reaction, the silica gel is subjected to surface modification through a silane coupling agent, and thus the silica gel has the effects of adsorption and enrichmenton Au(S2O3)<2><3-> complex ions in the thiosulfate gold leaching solution. Aiming at the problems of cyanide pollution and complex process generated when activated carbon loads copper cyanide complexions (Cu(CN)<4><2->) and loads prussian blue in the thiosulfate gold leaching industry, the silica gel is modified on the surface in a chemical bond combination mode, the pollution problem caused by organic matter leakage is reduced, the characteristics of stable adsorption material performance and simple adsorption technological process are achieved, and the application prospects are wide.
