Biosorption is becoming increasingly important for the treatment of pollutants due to its cost-effectiveness, environmental friendliness and efficiency. For a more sustainable environment, more studies need to focus on the application of real industrial effluents. Increasing the initial concentration of activated sludge increases the specific surface area of the sludge, which allows for greater sorption of sorbates. The optimal initial concentration of activated sludge in the process of biosorption of pollutants from pharmaceutical effluent was 5.12±0.13 g/L. The biosorption process can be described by the Temkin model, where the estimated values of B_T and A_T ranged from 29.11 to 76.08 and from 1.10 to 1.48 L/g, respectively. The overall efficiency of the biosorption process ranged from 9.5 to 40.2%. The removed toxicity averaged 41.1±7.88% for all experiments.

由于其成本效益、环境友好性和效率，生物吸附对于污染物的处理变得越来越重要。为了更可持续的环境，更多的研究需要关注实际工业废水的应用。增加活性污泥的初始浓度会增加污泥的比表面积，从而可以更好地吸附山梨酸盐。生物吸附制药废水污染物过程中活性污泥的最佳初始浓度为5.12±0.13 g/L。生物吸附过程可以用 Temkin 模型来描述，其中 B _T和 A _{T的估计值}范围分别为 29.11 至 76.08 和 1.10 至 1.48 L/g。生物吸附过程的总效率在 9.5% 到 40.2% 之间。对于所有实验，去除的毒性平均为 41.1±7.88%。
