Abstract
The critical shortage of phosphorus (P) resources and its associated environmental pollution underscore the urgent need for reducing P emission and recovering P. Non-orthophosphate species (phosphite, hypophosphite, and phosphonate), prevalent in industrial wastewater, contribute to water eutrophication, damage plant growth, and pose serious public health risks after discharging into the aquatic environment. These species are neglected despite their negative influences. Herein, we present a comprehensive review of non-orthophosphate species emphasizing their physicochemical properties, sources, detection methods, and toxicity. Moreover, we summarize and discuss recent advancements in biological, physicochemical (i.e., adsorption, Fenton, photocatalysis, catalytic oxidation, and Fenton-like), and electrochemical (i.e., electo-Fenton, photoelectron-Fenton, anodic oxidation, and electroadsorption) practices to remove and recover non-orthophosphate. In addition, we discuss the potential applications of these technologies, evaluate the processing efficiency and operating costs, and analyze the effects of the operating parameters. Finally, we provide a cutting-edge perspective regarding developing non-orthophosphate removal and recovery technologies that are more effective and affordable. We call for the development of cost-effective chemicals, high-quality electrodes, and enhancement of mass transfer efficiency to improve processing efficiency, deeper understanding of the reaction mechanism, and comprehensive evaluation of the recycled product to improve technology maturity and move toward industrialization.
期刊介绍：
ACS ES&T Engineering publishes impactful research and review articles across all realms of environmental technology and engineering, employing a rigorous peer-review process. As a specialized journal, it aims to provide an international platform for research and innovation, inviting contributions on materials technologies, processes, data analytics, and engineering systems that can effectively manage, protect, and remediate air, water, and soil quality, as well as treat wastes and recover resources.
The journal encourages research that supports informed decision-making within complex engineered systems and is grounded in mechanistic science and analytics, describing intricate environmental engineering systems. It considers papers presenting novel advancements, spanning from laboratory discovery to field-based application. However, case or demonstration studies lacking significant scientific advancements and technological innovations are not within its scope.
Contributions containing experimental and/or theoretical methods, rooted in engineering principles and integrated with knowledge from other disciplines, are welcomed.
