Provided is a high-concentration carbonyl sulfide conversion-absorption type desulfurizer for use at medium-low temperature and preparation method thereof. The desulfurizer comprises 50%-75% magnetic iron oxide red (FeO), 5%-10% alkali metal oxide (KO), 5-35% anatase TiO, and 5-10% shaping binder. The method of preparing the desulfurizer comprises: uniformly mixing a metatitanic acid prepared using ferrous sulfate recycled as a by-product from titanium dioxide production with KCO, calcining to activate at 500&#xb0; C.-700&#xb0; C., mixing with the magnetic iron oxide red and binder, roll molding at room temperature to form balls which are dried at 100&#xb0; C.-150&#xb0; C. to obtain the desulfurizer. The desulfurizer has a hydrolysis conversion of carbonyl sulfide higher than 99%, and has a higher sulfur capacity more than 25%.
