Hot metal pretreatment desulfurization slag was used as the adsorbent material,and a low concentration Ce3+ solu-tion was used to simulate a rare earth wastewater solution.The adsorption of Ce3+ by desulfurization slag was studied.X-ray diffractometer（XRD）,scanning electron microscope（SEM） and X-ray fluorescence spectrometry（XRF） were used to analyze the physical and chemical properties of the desulfurization slag.The effect of reaction time and initial concentration on the performance of Ce3+ adsorbed by the adsorbent to investigate the adsorption performance and mechanism of Ce3+ by desulfu-rization slag.The results showed that the desulfurization slag had a good adsorption effect on low-concentration Ce3+.At room temperature,the maximum adsorption rate of Ce3+ solution by the desulfurization slag was 96.8%.The reaction time and initial Ce3+ concentration had little effect on the desulfurization slag.
