采用共沉淀法和水热法分别制备了铁、钒和银、碳的双组分共掺杂改性TiO2吸附剂Fe-V-TiO2和Ag-C-TiO2,并分别以亚甲基蓝和活性艳红X-3B为目标物来评价吸附剂的活性;采用XRD、FT-IR、SEM等现代手段对吸附剂的理化性能进行详细表征.结果表明,成功制备了Fe-V-TiO2和Ag-C-TiO2纳米高效吸附剂,其吸附具有一定的选择性;吸附处理30 min,前者对100 ppm亚甲基蓝的脱色率达95.86%,后者对50 ppm活性艳红X-3B的脱色率达92.06%.

Two double component co-doped adsorbents,Fe-V-TiO2 and Ag-C-TiO2,were obtained by coprecipitation and hydrothermal method.Methylene blue and reactive brilliant red X-3B were used as target to evaluate their property respectively.The physicochemical properties of the adsorbents were characterized by XRD,FTIR and SEM.The results showed that Fe-V-TiO2 and Ag-C-TiO2 nano-adsorbents with high efficiency were successful prepared,and they have a certain selectivity.After adsorbing 30 minutes,the decolour rate of Fe-V-TiO2 for methylene blue （100 ppm） was up to 95.86% and Ag-C-TiO2 for reactive brilliant red X-3B （50 ppm） was 92.06%.
