摘要

如何从废旧电池回收过程中产生的复杂废水中完全吸附含磷有机物是一项关键的环境挑战。本工作的研究结果表明，在复杂的溶液体系中，离子可以显著改变含磷有机化合物的亲水性或结构形态，从而影响其吸附效果。基于这些见解，提出了一种基于离子调节的创新吸附策略，用于完全去除复杂废水中的含磷有机物。通过在吸附过程之前精确调节实际钴萃取废水中h30 +离子的浓度，我们实现了对含磷有机物的去除率超过99.98 %。这一突破为废电池回收领域复杂废水中有机污染物的综合去除提供了创新视角，为行业环境健康和可持续发展提供了重要保障。

Ionic effect enhanced the adsorption of phosphorus-containing organics (PCOs) from complex wastewater

Achieving the complete adsorption of phosphorus-containing organics from the complex wastewater generated during the recycling process of waste batteries is a critical environment challenge. The research findings of this work reveal that in complex solution systems, ions can significantly alter the hydrophilicity or structural morphology of phosphorus-containing organic compounds, thereby influencing their adsorption efficacy. Based on these insights, an innovative adsorption strategy based on ion-regulation was proposed for the complete removal of phosphorus-containing organics from complex wastewater. By precisely modulating the concentration of H₃O⁺ ions within actual cobalt extraction wastewater prior to the adsorption process, we achieved a removal rate exceeding 99.98 % for phosphorus-containing organics. This breakthrough offers innovative perspectives for the comprehensive removal of organic pollutants in complex wastewaters within the waste battery recycling sector and provides important guarantees for the industry’s environmental health and sustainable development.

期刊介绍： The Chemical Engineering Journal is an international research journal that invites contributions of original and novel fundamental research. It aims to provide an international platform for presenting original fundamental research, interpretative reviews, and discussions on new developments in chemical engineering. The journal welcomes papers that describe novel theory and its practical application, as well as those that demonstrate the transfer of techniques from other disciplines. It also welcomes reports on carefully conducted experimental work that is soundly interpreted. The main focus of the journal is on original and rigorous research results that have broad significance. The Catalysis section within the Chemical Engineering Journal focuses specifically on Experimental and Theoretical studies in the fields of heterogeneous catalysis, molecular catalysis, and biocatalysis. These studies have industrial impact on various sectors such as chemicals, energy, materials, foods, healthcare, and environmental protection.
