Effectively recovering local waste and utilizing it as adsorbents to absorb phosphate is crucial for resource utilization and mitigating water eutrophication. In this study, we successfully prepared SPS- spheres adsorbent (SPS-) using spent substrate (SPS) at 25 °C and pH = 6. The maximum surface area of SPS (185.22 m/g) SPS- obtained the highest P adsorption (126.65 mg P/g) at a dosing ratio of 30 g/L, which was 4–9 times higher than the adsorption capacity of other mycobacterial materials, which was caused by synergistic interactions between chemical and physical processes in the adsorption mechanism of phosphates. Remarkably, SPS- composite spheres demonstrate notable adsorption efficiency across diverse pollutants, particularly showing selective affinity for anionic pollutants. The practical applicability of SPS- composite spheres was assessed using real sewage samples, achieving an impressive removal rate of over 80 % under dynamic flow conditions. This approach highlights the potential of biosorbents in addressing environmental challenges while achieving sustainability and renewability.

一种可再生生物吸附剂制造的绿色木霉复合球，填充有废桑黄基质，在宽范围 pH 值下可有效去除水中的磷酸盐


有效回收当地废物并利用其作为吸附剂吸收磷酸盐对于资源利用和缓解水体富营养化至关重要。在本研究中，我们在 25 °C 和 pH = 6 下使用废基质 (SPS) 成功制备了 SPS-球吸附剂 (SPS-)。SPS 的最大表面积 (185.22 m/g) SPS- 获得了最高的 P 吸附 ( 126.65 mg P/g），添加比例为30 g/L，比其他分枝杆菌材料的吸附能力高4-9倍，这是由磷酸盐吸附机制中化学和物理过程之间的协同相互作用引起的。值得注意的是，SPS 复合球对多种污染物表现出显着的吸附效率，特别是对阴离子污染物表现出选择性亲和力。使用真实污水样品评估了 SPS 复合球的实际适用性，在动态流动条件下实现了超过 80% 的令人印象深刻的去除率。这种方法凸显了生物吸附剂在应对环境挑战、同时实现可持续性和可再生性方面的潜力。
