On the contrary, there is a significant amount of phosphorus waste causing serious environmental problems. The clear contrast has raised deep concerns about future phosphorus supply shortages and widespread environmental issues. In this study, CoNi-LDH/CNTs hybrid films were prepared by drop-coating and electrodeposition, and then used for the recovery of phosphorus ions from wastewater via an electrically switched ion exchange (ESIX) method. During the experimental process, it was found that CNTs can not only improve the conductivity of the film, but also serve as a support material for LDH to avoid agglomeration. In addition, the electrochemical adsorption capacities of CoNi-LDH/CNTs for phosphate were measured under different conditions. The results show that CoNi-LDH/CNTs recover the PO₄³⁻ by a potential-induced electrostatic attraction and ligand exchange mechanism. Furthermore, CoNi-LDH/CNTs exhibited an outstanding electrochemical adsorption capacity for PO₄³⁻ and high exclusivity toward other coexisting anions. Moreover, CoNi-LDH/CNTs could be used over a wide pH range (pH = 4–10). Therefore, CoNi-LDH/CNTs can be used in the ESIX process to achieve effective phosphorus removal and recovery from wastewater.</p>","PeriodicalId":665,"journal":{"name":"Journal of Solid State Electrochemistry","volume":"30 2","pages":"855 - 863"},"PeriodicalIF":2.6,"publicationDate":"2025-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146071323","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The morphology and structure of the deposits were examined using SEM and XRD methods. Scanning electron microscopy revealed that trajectories where the electrode moves over small distances between adjacent deposition points (concentric or zigzag) result in the formation of a less homogeneous layer with characteristic porosity, globule formation, or grain agglomeration. In contrast, the use of a triangular trajectory leads to a more uniform, dense layer with evenly distributed grain structure. X-ray diffraction analysis showed that the largest crystallites are formed with zigzag infill, smaller ones are formed with concentric and triangular trajectories. Increasing the infill step reduces the crystallite size. The type of slicing also affects internal stresses in the deposit. The least stressed deposits are obtained with concentric infill, slightly higher stresses with triangular infill, but in both cases, increasing the infill step reduces internal stresses.

An organohydroxyapatite (OHAP) hybrid material was prepared by cross-linking grafting β-cyclodextrin (β-CD) with citric acid (CA) at the surface of an impregnated natural hydroxyapatite (HAPI). The structural characterization of HAPI and OHAP materials was performed using SEM–EDX. Thin films of different materials were deposited on the surface of a glassy carbon electrode (GCE); their surface charge and permeability were evaluated by multisweep cyclic voltammetry using [Fe(CN)₆]^3−/4− and [Ru(NH₃)₆]^3+/2+ as redox probe systems. The electrochemical behavior of MB on the GCE modified by a film of HAPI or OHAP was also studied by cyclic voltammetry. As with [Ru(NH₃)₆]³⁺ ions, the cyclic voltammograms obtained showed that MB molecules are quantitatively and progressively accumulated on OHAP thin film. Then, the GCE/OHAP electrode was exploited to build a sensitive sensor for the detection of MB. In comparison with the bare GCE, the GCE/OHAP exhibited more sensitive electrochemical response toward MB.
