Magnetic chicken bone biochar (MCB) was fabricated and characterised. The specific surface area, magnetisation value and pH of the MCB were found to be 328 m g, 64.7 emu/g and 8.3 respectively. The adsorptive performance of MCB for rhodamine B dye (RB) and tetracycline (TC) removal in a single and two-stage stirred adsorber (TSA) was evaluated. The TSA reduced the pressure drops, mass transfer resistances, and fouling of the adsorbent. 63.0 g MCB is required to remove 75% of RB and TC in a single-stage system within 12 h. However, the optimised TSA confirmed that 33.2 g of MCB is needed to achieve 96% removal of TC and 22.2 g for RB within 180 min of 100 mgL effluent solutions. The sorption was suitably described by the Freundlich mechanism. Based on the comparative performance, the MCB is considered a viable efficient and magnetically separable alternative adsorbent.
磁性鸡骨生物炭 (MCB) 被制备和表征。发现 MCB 的比表面积、磁化值和 pH 值分别为 328 m g、64.7 emu/g 和 8.3。评估了 MCB 在单级和两级搅拌吸附器 (TSA) 中对罗丹明 B 染料 (RB) 和四环素 (TC) 去除的吸附性能。TSA 降低了压力降、传质阻力和吸附剂的污垢。在单级系统中，需要 63.0 g MCB 在 12 小时内去除 75%的 RB 和 TC。然而，优化后的 TSA 证实，在 100 mgL 流出液中，需要 33.2 g 的 MCB 才能实现 96%的 TC 去除率，需要 22.2 g 的 MCB 才能实现 22.2 g 的 RB 去除率。吸附过程可以用 Freundlich 机制来描述。基于比较性能，MCB 被认为是一种可行的高效且可磁分离的替代吸附剂。
