Biosorption of Reactive Black 5 (RB 5) dye onto dried Penicillium restrictum biomass was studied with respect to pH, contact time, biosorbent and dye concentrations. The effect of temperature on the biosorption efficiency was also carried out and the kinetic parameters were determined. Optimum initial pH, equilibrium time and biomass concentration for RB 5 dye were found to be 1.0, 75 min and 0.4 g dm(-3) at 20 degrees C, respectively. The maximum biosorption capacities (q(max)) of RB 5 dye onto dried P. restrictum biomass were 98.33 and 112.50mg (g biomass)(-1) at 175 mg dm(-3) initial dye concentration at 20 and 50 degrees C, respectively, and it was 142.04 mg (g biomass)(-1) at 200 mg dm(-3) initial dye concentration at 35 degrees C. The results indicate that the biosorption process obeys a pseudo-second-order kinetic model.
研究了活性黑5（RB 5）染料在干燥的局限青霉生物质上的生物吸附，考察了pH值、接触时间、生物吸附剂浓度和染料浓度的影响。还研究了温度对生物吸附效率的影响并确定了动力学参数。发现在20℃下，RB 5染料的最佳初始pH值、平衡时间和生物质浓度分别为1.0、75分钟和0.4 g dm(-3)。在20℃和50℃下，初始染料浓度为175 mg dm(-3)时，RB 5染料在干燥的局限青霉生物质上的最大生物吸附容量（q(max)）分别为98.33和112.50mg (g生物质)(-1)，在35℃下，初始染料浓度为200 mg dm(-3)时，最大生物吸附容量为142.04 mg (g生物质)(-1)。结果表明，生物吸附过程符合准二级动力学模型。
