英文摘要	采用黑曲霉(ASPErgIlluS nIgEr)菌粉为生物吸附剂,以直接耐晒翠蓝199(fbl)染料为吸附对象,系统考察了PH值、反应温度和染料质量浓度对脱色性能的影响,研究了吸附反应动力学特性.结果表明,当PH在3.0~7.0的范围、吸附平衡时间为40MIn时,吸附量达到最大的7.50~8.2Mg/g;当染料质量浓度为400Mg/l、温度从25℃升至45℃时,吸附量从18.34Mg/g增至29.96Mg/g;黑曲霉菌粉对fbl的吸附速率主要取决于化学吸附反应速率,吸附反应过程符合准二级反应动力学模型.; The phthalocyanine dye C.I.Direct Blue 199,widely used the textile industry,contains a copper ion in its structure,a could possibly be removed from aqueous solution by inactive niger,which has a high adsorption ability for copper ions.However,no study has so far been focused on the biosorptability of inactive Aspergillus niger for this dye.In this study,nonviable Aspergillus niger powder was used for the biosorption of C.I.Direct Blue 199in a batch system.The major objective was to investigate the influences of pH,temperatures and initial dye concentration on the biosorption capacity,and to study the biosorption kinetics of Aspergillus niger powder.The results showed that the highest biosorption capacity of powdered Aspergillus niger for C.I.Direct Blue 199was 7.50-8.24mg/g at pH 3.0-7.0.The maximum dye uptake capacity of the biosorbent increased from 18.34mg/g to 29.96mg/g at 400mg/L dye concentration by increasing the temperature from 25℃to 45℃.Adsorption kinetics followed the pseudo-second order equation,which suggested that chemisorption significantly contributed to the adsorption process.; 福建省重大专项研究项目(2005YZ1023); 厦门市科技计划项目(3502Z20083001)
