Herein, and were evaluated for the uptake of the methylene blue (MB) dye. Various factors such as pH range, time of exposure, dye concentration, adsorbed quantity, etc. have been studied for the uptake. Adsorption isotherms investigated in this study include the Langmuir and Freundlich isotherms. The Langmuir isotherm has been long known to be the best fit in the process of adsorption. The maximum monolayer adsorption capacity for was reported to be 0.5210 mol/kg, and it is 1.8387 mol/kg for at 298 K. The values 0.8748 and 0.9524 obtained indicate that the dye is favorably adsorbed on both adsorbents. Kinetics data analysis has shown that methylene blue adsorbed on the fungus showed pseudo-second-order chemisorption and film as well as intra particle diffusion. These results reveal that the abovementioned fungi can be used as good sources for the uptake of the MB dye.
在此，对[具体物质1]和[具体物质2]进行了亚甲基蓝（MB）染料摄取的评估。针对摄取研究了各种因素，如pH范围、暴露时间、染料浓度、吸附量等。本研究中研究的吸附等温线包括朗缪尔等温线和弗伦德利希等温线。长期以来已知朗缪尔等温线最适合吸附过程。据报道，[具体物质1]在298K时的最大单层吸附容量为0.5210 mol/kg，[具体物质2]的为1.8387 mol/kg。获得的[具体数值1]为0.8748和[具体数值2]为0.9524表明染料在两种吸附剂上均被良好吸附。动力学数据分析表明，吸附在真菌上的亚甲基蓝表现出拟二级化学吸附以及膜扩散和颗粒内扩散。这些结果表明上述真菌可作为摄取MB染料的良好来源。
