1. A resin substrate-based iron oxyhydroxide desulfurizing agent, prepared by adding iron oxyhydroxide to a resin substrate, with a mass ratio of the iron oxyhydroxide to resin being 40-80:5-10, wherein
the resin is prepared by condensation polymerization of p-aminophenol and formaldehyde to form a linear phenolic resin, followed by modifying the linear phenolic resin with terephthalyl alcohol.
