These NPs, characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared (FTIR) spectroscopy, and UV–visible spectroscopy, revealed a pure crystalline phase. The crystallite sizes, estimated at 62.25 nm and 30.84 nm using the Scherrer and Williamson-Hall equations, confirm their nanometric structure. FTIR spectra highlighted vibrations of Mn<img>O and Mn-O-Mn bonds, while UV–visible spectroscopy showed an absorption band at 388 nm and a secondary peak at 533 nm, indicating a bandgap energy (E_g) of 1.51 eV. The electrode modification was validated by cyclic voltammetry (CV), revealing a 34 % increase in the electroactive surface area (EASA), enhancing sensitivity for Cd(II) and Pb(II) detection. Detection was performed using square wave anodic stripping voltammetry (SWASV), and conditions (NPs mass, accumulation time and deposition potential) were optimized. The sensor demonstrated a working range of 0.1 μM to 100 μM with detection limits of 0.07 μM for Cd(II) and 0.19 μM for Pb(II). Interference studies have demonstrated the high sensitivity and selectivity of the sensors. Its feasibility was evaluated on real samples, including wastewater from Bni Bounsar (Morocco), using the standard addition method to minimize matrix effects. The obtained recovery rates ranging from 84 % to 95 % for Cd(II) and 80 % to 94 % for Pb(II), highlight its accuracy and reliability. These results confirm its applicability for environmental monitoring and the effective detection heavy metals.</div></div>","PeriodicalId":17528,"journal":{"name":"Journal of water process engineering","volume":"75 ","pages":"Article 107928"},"PeriodicalIF":6.3,"publicationDate":"2025-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143941349","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study developed a rapid online monitoring technique for nitrate by rapidly forming a cathodic EAB through electrode polarity reversal. This resulted in a maximum current density of −3 A m⁻² for the biocathode. Nitrate functions as an electron acceptor, with biocathode-attached microorganisms either directly or indirectly acquiring electrons from the biocathode surface to reduce nitrate for metabolic sustenance.

The photocatalyst demonstrated excellent reusability, maintaining 86.5 % efficiency over five cycles without significant loss of activity.

It is suggested that the copper nanoparticles interact with the mobile groups of polyaniline via electrostatic forces.

The electrochemical performance of the Cu-PANI NCs toward 4-AP is assessed through voltammetry (C<em>V</em>) and differential pulse voltammetry (DPV). It is noted that the glassy carbon electrode (GCE) modified with Cu-PANI (Cu-PANI NCs@GCE) shows an outstanding CV response in the presence of a supporting electrolyte (0.1 M H₂SO₄) at 0.52 V.
