The effect of solid state fermentation of peanut shell to produce beneficial laccase and on its dye adsorption performance was evaluated. The resulting residues from solid fermentation were tested as sorbents (designated as SFs) in comparison to the raw peanut shell (RPS) for their ability to remove crystal violet from water. The fermentation process reduced the adsorption capacity (q) of SF by about 50%, and changed the sorptive behavior when compared to the RPS. The Langmuir model was more suitable for fitting adsorption by SFs. q was positively correlated with the surface area of peanut shell, but negatively correlated with acid detergent lignin content. For all the sorbents tested, the process was spontaneous and endothermic, and the adsorption followed both the pseudo 1st and 2nd order kinetic model and the film diffusion model. Dye adsorption efficiency was greater when SFs dispersed solution than when placed in filter packets.
评价了花生壳固态发酵生产有益漆酶及其对染料吸附性能的影响。将固态发酵得到的残余物用作吸附剂（命名为 SF），并与原始花生壳（RPS）进行比较，以评估其从水中去除结晶紫的能力。发酵过程使 SF 的吸附容量（q）降低了约 50%，与 RPS 相比，其吸附行为也发生了变化。Langmuir 模型更适合拟合 SF 的吸附。q 与花生壳的比表面积呈正相关，但与酸洗涤剂木质素含量呈负相关。在所测试的所有吸附剂中，该过程都是自发和吸热的，吸附同时遵循准一级和准二级动力学模型以及膜扩散模型。当 SF 分散在溶液中时，染料吸附效率大于将其置于过滤包中时的效率。
