摘　　要：以SiW_(11)Cr/PANI为吸附剂,考察了其对染料废水刚果红的吸附性能。结果表明:浓度为45 mg/L的刚果红溶液,SiW_(11)Cr/PANI用量9 mg,溶液酸度为6的条件下,SiW_(11)Cr/PANI吸附降解刚果红,脱色率可达到90.98%,吸附量达到183.48 mg/g。能够用准二级吸附动力学方程较好的描述其吸附过程,具有良好的吸附性能且可重复利用。The with SiW_(11)Cr/PANI as the adsorbents,the adsorption performance of the composite for Congo red dye wastewater was studied.The results show that the adsorption rate of Congo red reach 90.98%,adsorption capacity of up to 183.48 mg/g when the concentration of Congo red solution was 45 mg/L,SiW_(11)Cr/PANI dosage was 9 mg,solution acidity was 6.The adsorption process can be well described by pseudo second order adsorption kinetic equation,which has good adsorption performance and can be reused.
