Exposure to thallium (Tl), a noxious heavy metal, poses significant health risks both humans and animals upon ingestion. Therefore, monitoring Tl levels in the environment is crucial prevent human exposure reduce risk of developing severe problems. This paper presents development highly sensitive ions sensor through surface modification glassy carbon electrode with nanocomposite comprising MnO2 magnetic sepiolite multi-walled nanotubes (MnO2@Fe3O4/Sep/MWCNT/GCE). Multiple methodologies were employed assess performance newly developed sensor. By employing square wave anodic stripping voltammetry (SWASV) optimize measurement conditions, notable enhancements observed peak currents (I) on MnO2@Fe3O4/Sep/MWCNT/GCE surface. The effectiveness facilitating electron transfer between (guest) (host) was demonstrated from enhanced signals at different modified surfaces under optimal conditions. displayed wide linear range 0.1–1500 ppb for low detection limit 0.03 (I). It found be selective while remaining unaffected by interfering non-target presence target ions. Despite its simple preparation procedure, exhibited high stability excellent reproducibility measuring outstanding electroanalytical performances enabled successful use as an ultrasensitive determining trace amounts environmental samples.

The presence of antibiotics in wastewater has become a significant concern due to their potential environmental impact and contribution antibiotic resistance. In this study, we investigated the degradation tetracycline, commonly used antibiotic, using system based on zero-valent nano iron assisted micro-nano bubbles (MB/nZVI). synthesized nZVI-BC composite, consisting particles loaded onto phosphoric acid-activated biochar, served as an efficient adsorbent for tetracycline removal. Our findings revealed that combination MBs nZVI significantly enhanced efficiency tetracycline. MB/nZVI exhibited highest removal rate 82.81% after 2 h reaction, surpassing performance MB alone, conventional bubble (CB)/nZVI-BC systems. Furthermore, showed superior at dosage 25 g/L flow 30 mL/min. pH condition had no effect system. results demonstrate use be sustainable approach remediation tetracycline-contaminated wastewater.
