Electrochemical treatment of antibiotic wastewater containing ceftriaxone sodium by porous Ti/Magnéli Ti4O7 nanotube arrays
In this study, porous Ti/Magnéli Ti4O7 nanotube arrays (NTA) was fabricated to pretreat antibiotic wastewater. Characterization of the Ti4O7-NTA illustrated that highly ordered NTA was successfully generated on the porous Ti substrate, which enlarged the specific surface area by 1.67 times. The Ti4O7-NTA has a high oxygen evolution potential (2.60 V) as well as low interfacial charge transfer resistance (4.479 Ω cm−2). Ceftriaxone sodium (CRO) was completely removed from raw antibiotic wastewater after 3 h of treatment by the Ti4O7-NTA, under optimal operation conditions. The biodegradability and toxicity of the wastewater were also significantly enhanced and reduced, as the BOD/COD and EC50,48h values were increased to 0.48 and 57.62 % ± 2.16 %, respectively. The possible degradation pathway of CRO was proposed by LC‒MS. Cathodic polarization was proven to be an effective way to ensure the long-term durability of the Ti4O7-NTA.

Water Resources and Industry moves research to innovation by focusing on the role industry plays in the exploitation, management and treatment of water resources. Different industries use radically different water resources in their production processes, while they produce, treat and dispose a wide variety of wastewater qualities. Depending on the geographical location of the facilities, the impact on the local resources will vary, pre-empting the applicability of one single approach. The aims and scope of the journal include: -Industrial water footprint assessment - an evaluation of tools and methodologies -What constitutes good corporate governance and policy and how to evaluate water-related risk -What constitutes good stakeholder collaboration and engagement -New technologies enabling companies to better manage water resources -Integration of water and energy and of water treatment and production processes in industry
