Preparation and Characterization of Cross-linked Modified Walnut Shell
摘要
Abstract
Using discarded walnut shells as raw materials,a series of modified walnut shell adsorbents were successfully prepared through alkali activation and epichlorohydrin cross-linking modification.The effects of cross-linking time on the structure and properties of the materials were systematically investigated.The materials were characterized by infrared spectroscopy(FT-IR),X-ray diffraction(XRD),and simultaneous thermal analysis(TG-DSC).The results indicated that cross-linked structures were successfully introduced during the modification process,and the crystallinity of the materials was significantly improved.A stable network structure formed through moderate cross-linking,and delays the initiation of thermal decomposition.Swelling performance test demonstrated that the sample cross-linked for 1 hour exhibited optimal water absorption,with a swelling ratio as high as 81.0%,providing a feasible approach for the resource utilization of walnut shells.关键词
