摘　　要：对水体中有机染料类物质的污染的治理,历来为人们所关注。文中选用壳聚糖为基底材料,通过固相研磨法对二氧化钛进行负载,通过进一步煅烧制备了负载TiO_(2)的壳聚糖材料:利用SEM观察了材料的微观结构;通过XPS、TG、FTIR、DRS等测试研究了其理化特性;最后通过有机染料维多利亚蓝B的吸附降解实验,综合评价了材料对其有机染料维多利亚蓝B的处理性能。所制备的材料0.25-CT-210具有良好的吸附和光催化降解性能,在90 min内通过吸附和降解实现了对维多利亚蓝B90%以上的脱色。The increasing chemical pollution in aquatic environments has drawn global attention.Chitosan,a naturally derived polysaccharide from chitin,exhibits excellent adsorption capabilities after deacetylation.This study utilized chitosan as a base material and loaded titanium dioxide through solid-phase grinding.The microstructure of the materials was observed using SEM.The physicochemical properties were analyzed through tests including XPS,TG,FT-IR,and DRS.Finally,by conducting adsorption and degradation experiments using the organic dye Victoria Blue B,the materialʼs performance in treating the organic dye Victoria Blue B was comprehensively evaluated.The prepared material,named 0.25-CT-210,demonstrated remarkable adsorption and photocatalytic degradation properties.Within 90 minutes,it achieved over 90%decolorization of Victoria Blue B through adsorption and degradation.
