Aspergillus parasiticus (A. parasiticus) CBS 100926 was used as a biosorbent for the removal of Methylene Blue (MB), Congo Red (CR), Sudan Black (SB), Malachite Green Oxalate (MGO), Basic Fuchsin (BF) and Phenol Red (PR) from aqueous solutions. The batch biosorption studies were carried out as a function of dye concentration and contact time. The biosorption process followed the pseudo-first-order and the pseudo-second-order kinetic models and the Freundlich and Langmuir isotherm models. The resulting biosorbent was characterized by Scanning Electron Microscopy (SEM), X-Ray Diffractometer and Fourier Transformer Infrared Spectroscopy (FTIR) techniques. The results of the present investigation suggest that A. parasiticus can be used as an environmentally benign and low cost biomaterial for the removal of basic and acid dyes from aqueous solution.
寄生曲霉（A. parasiticus）CBS 100926被用作生物吸附剂，用于从水溶液中去除亚甲基蓝（MB）、刚果红（CR）、苏丹黑（SB）、草酸孔雀石绿（MGO）、碱性品红（BF）和酚红（PR）。批次生物吸附研究作为染料浓度和接触时间的函数进行。生物吸附过程遵循伪一级和伪二级动力学模型以及弗伦德利希和朗缪尔等温线模型。通过扫描电子显微镜（SEM）、X射线衍射仪和傅里叶变换红外光谱（FTIR）技术对所得生物吸附剂进行了表征。本研究结果表明，寄生曲霉可作为一种环境友好且低成本的生物材料，用于从水溶液中去除碱性和酸性染料。
