摘    要:利用稻壳为模板和硅源合成Fe3+,Co2+,Ni2+,Cu2+,Zn2+,Cd2+,Ag+,Pb2+等8种过渡金属离子掺杂的M-TiO2-SiO2吸附剂,研究其在室温避光条件下对番红花T和龙胆紫染料水溶液吸附性能的差异.研究结果表明:掺杂第四周期过渡金属离子的M-TiO2-SiO2吸附剂的吸附性能随着过渡金属离子3d轨道电子数的增加,吸附性能呈现出先增大后减小的趋势;掺杂副族金属离子的M-TiO2-SiO2吸附剂的吸附性能随着金属离子主量子数的增大,吸附性能增大.

关 键 词:稻壳  M-TiO2-SiO2  过渡金属离子  核外电子排布  吸附性能

Abstract:The M-TiO2-SiO2(M:Fe,Co,Ni,Cu,Zn,Cd,Ag,Pb)were synthesized through rice husks as both silicon source and template and they were used for the absorption of removal dyes.The results indicated that M-TiO2-SiO2 exhibited higher absorption of removal dyes than that of P25,and the absorption yields of removal dyes were about 80% for gentian violet and safranine T.Furthermore,with atomic number increased,the M-TiO2-SiO2 absorption of removal dyes first increased,then decreased in the four cycle number metal.The Ni...
Keywords:rice husk  M-TiO2-SiO2  extranuclear electronic configuration  adsorptive activity
