Novel Methods for Orthophosphate RapidDetection and Adsorption Applications ; Méthodes Novatrices pour la Détecon Rapide et les Applicaons d'Adsorpon de l'Orthophosphate

2-phosphonobutane-1,2,4-tricarboxylic acid (PBTC) is an orthophosphate reagent widely used as a corrosion inhibitor to prevent scale deposits. Monitoring PBTC levels in industrial systems presents significant challenges due to the lack of online or internal methods for control and measurement. While overdose of PBTC, it can lead to unnecessary chemical waste and negatively impact conventional wastewater treatment processes. Thus, the novel strategies for rapid detection and enhanced adsorption have been required. In adsorption, polyethylene terephthalate bottle waste was upcycled into aluminum-based metal-organic frameworks adsorbent, integrating waste management with water purification solutions. Layer-by-layer fabricated magnetic adsorbents further demonstrated structural integrity and efficiency under diverse environmental conditions. For detection, amine-functionalized polystyrene latex nanoparticles were synthesized via emulsifier-free emulsion polymerization. The material enables simple PBTC monitoring through latex agglutination, providing map aggregation domains across varying pH levels. Additionally, electrochemical impedance spectroscopy microsensors, based on molecularly imprinted polymers, offer high sensitivity and selectivity for PBTC detection, offering in situ Lab-on-Chip applications with drop-casting analysis. ; L'acide 2-phosphonobutane-1,2,4-tricarboxylique (PBTC) est un réactif orthophosphate largement utilisé comme inhibiteur de corrosion, particulièrement efficace pour prévenir le dépôt de tartre. Cependant, la surveillance des niveaux de PBTC dans les systèmes industriels pose des défis majeurs, notamment en raison de l'absence de méthodes de contrôle et de mesure disponibles en ligne ou sur site. Un surdosage de PBTC peut non seulement entraîner un gaspillage chimique inutile, mais également perturber les processus conventionnels de traitement des eaux usées. Par conséquent, il est crucial de développer des stratégies innovantes pour une détection rapide etefficace de ce composé. En ...
