研究了酵母菌对阳离子染料藏红T的吸附性能,考察了溶液pH和染料初始浓度对吸附过程的影响,研究了等温模型和吸附动力学。结果表明,pH对吸附效率的影响较大,最佳pH值为6；染料浓度在15~55 mg/L范围内,吸附量随着浓度的增加而增加。吸附过程符合准一级动力学模型和Langmuir等温模型,为单分子层物理吸附。

Yeasts adsorbents were used to absorb the cationic Safranine T from aqueous solutions. Factors affecting the adsorption process including pH and dye concentration were investigated,respectively. The re-sults show that pH has a significant impact on the adsorption efficiency and the optimal pH value is 6. The dye concentration is 15~55 mg/L,the adsorption capacity is enhanced with the increasing of initial concen-tration. The pseudo-first-order kinetic equation is suitable for fitting the adsorption process,indicating the process is dominated by physical absorption. The Langmuir model was found to be in better correlation with the experimental data,which shows that the absorption belongs to monolayer molecular adsorption.
