Absorbent used for removing sulfides in malodorous gases

The invention provides an absorbent used for removing sulfides in malodorous gases and a preparation method thereof, and aims at solving the problems that the existing desulfurization methods have high operating cost, poor desulfurization effects and high solvent cost. The absorbent is prepared from the following raw materials of water, sodium hydroxide or potassium hydroxide, a sodium salt of ethylene diamine tetra-acetic acid (EDTA) or sodium tartrate, p-benzoquinone or tannin, vanadium pentoxide or sodium metavanadate and ethanolamine according to the preparation method provided by the invention. The absorbent can absorb hydrogen sulfide, mercaptans, thioethers and other sulfur-containing acidic gases, and has low cost and a wide application range, the removal rate of hydrogen sulfide is more than 99% and the removal rate of other organic sulfurs is more than 90%.
