采用不同参数（例如吸附剂剂量、pH、温度和离子强度）研究了天然和处理的白腐真菌“Lentinus sajur-caju”生物质制剂从水溶液中去除纺织染料（即活性红-120）的能力和机制。在批量系统中，在 pH 3.0 时观察到所有测试的真菌生物质制剂的最大染料吸收，并且发现对于天然和热、酸和碱处理的干真菌制剂，生物吸附剂（在 800 mg/l 染料浓度）的染料吸收能力分别为 117.8、182.9、138.6 和 57.2 mg/g。真菌制剂对染料的吸收能力顺序为热处理>酸处理>天然>碱处理。 Langmuir、Freundlih 和 Temkin 吸附模型用于生物吸附平衡的数学描述。 Freundlich 和 Temkin 模型能够描述活性红 120 在真菌生物质制剂上的生物吸附平衡。真菌生物质制剂上的染料生物吸附遵循二级动力学模型和方程。 (c) 2007 Elsevier B.V. 保留所有权利。
The capacities and mechanisms of native and treated white-rot fungus "Lentinus sajur-caju" biomass preparations in removing of textile dye (i.e. Reactive Red-120) from aqueous solution was investigated with different parameters, such as adsorbent dosage, pH, temperature and ionic strength. In the batch system, the maximum dye uptake on all the tested fungal biomass preparations was observed at pH 3.0, and the dye uptake capacities of the biosorbents (at 800 mg/l dye concentration) were found to be 117.8, 182.9, 138.6 and 57.2 mg/g for native and heat-, acid- and base-treated dry fungal preparations, respectively. The uptake capacities order of the fungal preparations for the dye were found as heat-treated > acid-treated > native > base-treated. The Langmuir, Freundlih and Temkin adsorption models were used for the mathematical description of the biosorption equilibrium. The Freundlich and Temkin models were able to describe the biosorption equilibrium of Reactive Red-120 on the fungal biomass preparations. The dye biosorption on the fungal biomass preparations followed second-order kinetic model and equation. (c) 2007 Elsevier B.V. All rights reserved.
