Abstract

Abstract:

Aspergillus flavus A5P1 was used as raw material to prepare biosorbent A5P1_acid by hydrochloric acid modification，which was used to adsorb acid blue 25（AB25） dyes. Batch experiments were used to explore different influencing factors. The results showed that the optimum amount of adsorbent and pH for dye adsorption was 0.5 g/L and 2，and the adsorption reached equilibrium in 60 min. Compared with unmodified adsorbents，the adsorption capacity of acid modified adsorbents increased from 137 mg/g to 182 mg/g，and the dye removal rate increased to 32%. The thermodynamics，kinetics and adsorption isotherm of AB25 removed by A5P1_acid adsorption were studied. The adsorption process met the quasi-second-order kinetic model，and the adsorption rate was controlled by chemical adsorption. Moreover， it met the Freundlich adsorption isotherm，and the adsorption belonged to multi-layer heterogeneous adsorption. The thermodynamic results showed that it was an endothermic spontaneous adsorption process. The results of Zeta potential and FTIR showed that the adsorption was assigned to the electrostatic adsorption and hydrogen bonding of various functional groups. The adsorbent still retained 50.6% of the initial adsorption capacity after cyclic adsorption-desorption for 7 times. The experimental results showed that A5P1_acid was a green and effective biological adsorbent material which could be used to remove anionic dyes.

Key words: Aspergillus flavus, adsorption, acid modification, dye decolorization

摘要：

以黄曲霉A5P1为原料，利用盐酸改性法制成生物吸附剂A5P1_acid，用于吸附酸性蓝25（AB25）染料。对A5P1_acid吸附的影响因素进行分析，结果表明：染料吸附的最佳吸附剂用量为0.5 g/L，最适pH为2，60 min达到吸附平衡。吸附剂经盐酸改性后，吸附量从137 mg/g提高到182 mg/g，染料去除率提高了32%。通过分析A5P1_acid吸附去除AB25的机理，发现吸附过程符合准二级动力学模型，是由化学吸附控制吸附速率；符合Freundlich吸附等温线，吸附属于多层非均相吸附。热力学结果表明吸附过程是一个吸热自发的过程。Zeta电位和FTIR结果表明，吸附是由多种官能团的静电吸附和氢键作用的。吸附剂经过循环吸附-解吸7次仍保留初始吸附量的50.6%。实验研究证明，A5P1_acid是一种绿色有效可用于去除阴离子染料的生物吸附质材料。
