This research study encompasses the utilization of new adsorbents fabricated from pine sawdust for the adsorption of heavy metals and phenol from simulated industrial wastewater. Batch trials are conducted to evaluate the activity of these adsorbents for a possible substitution of the costly commercial adsorbents. The maximum adsorption capacities are evaluated and linked to the physicochemical characteristics of the adsorbents. The maximum monolayer adsorption capacity (q_max) of the adsorbents corresponds to the specific surface area of the adsorbents. The adsorbents with the larger specific surface area have shown higher q_max estimates (phenol adsorption is an exception). The highest amount of the phenol pollutant adsorbed by steam-activated sawdust (SAS) is 10.0 mg/g. The performance of SAS is found to be of the same order as the commercial activated carbon for the removal of Pb and Zn. Equilibrium data for the metal removal are in concordance with the Freundlich adsorption isotherm, whereas the phenol elimination has satisfied the Langmuir adsorption isotherm model. Kinetic data are fitted to Lagergren pseudo-first-order, pseudo-second-order, and the intraparticle diffusion models. Thus, kinetic parameters, rate constants, equilibrium adsorption capacities, and related correlation coefficients for each kinetic model are determined and discussed. The results suggest that the adsorption of Cr follows pseudo-second-order kinetics, indicating chemisorption for the tested adsorbents such that the intraparticle diffusion is not the only step that controls the overall process for Cr adsorption. At the end of this study, the production cost of the SAS adsorbent is estimated ($52 per kg) and compared to the cost of the commercial AC adsorbent in the industrial sector which has a great variation ($80–300 per kg) based on size and location plant. The results of this study can be used for the design of a suitable ecological control procedure to mitigate the harmful effects of industrial wastewater.

这项研究包括利用由松木屑制成的新型吸附剂来吸附模拟工业废水中的重金属和苯酚。进行批量试验以评估这些吸附剂的活性，以替代昂贵的商业吸附剂。评估最大吸附容量并与吸附剂的物理化学特性相关联。吸附剂的最大单层吸附容量 ( q _max ) 对应于吸附剂的比表面积。具有较大比表面积的吸附剂表现出较高的q _max估计（苯酚吸附是一个例外）。蒸汽活化锯末 (SAS) 吸附的酚类污染物的最高量为 10.0 mg/g。发现 SAS 的性能与用于去除 Pb 和 Zn 的商业活性炭的性能相同。金属去除的平衡数据与 Freundlich 吸附等温线一致，而苯酚消除满足 Langmuir 吸附等温线模型。动力学数据拟合 Lagergren 伪一阶、伪二阶和粒子内扩散模型。因此，确定和讨论了每个动力学模型的动力学参数、速率常数、平衡吸附容量和相关相关系数。结果表明Cr的吸附遵循准二级动力学，表明测试吸附剂的化学吸附，因此颗粒内扩散不是控制 Cr 吸附整个过程的唯一步骤。在本研究结束时，估计 SAS 吸附剂的生产成本（每公斤 52 美元），并与工业部门的商业 AC 吸附剂的成本进行比较，后者根据尺寸的不同有很大差异（每公斤 80-300 美元）和位置工厂。本研究的结果可用于设计合适的生态控制程序，以减轻工业废水的有害影响。SAS 吸附剂的生产成本是估算的（每公斤 52 美元），并且与工业部门的商业 AC 吸附剂的成本相比，根据工厂的规模和位置，该成本有很大的变化（每公斤 80-300 美元）。本研究的结果可用于设计合适的生态控制程序，以减轻工业废水的有害影响。SAS 吸附剂的生产成本是估算的（每公斤 52 美元），并且与工业部门的商业 AC 吸附剂的成本相比，根据工厂的规模和位置，该成本有很大的变化（每公斤 80-300 美元）。本研究的结果可用于设计合适的生态控制程序，以减轻工业废水的有害影响。
