Abstract: This research paper focuses on the assessment of the sensitivity and selectivity of macrocyclic-based heterogeneous membrane sensors for monitoring bivalent (Bi) and trivalent metal ions. The objectives of the study were to evaluate the performance of these sensors in detecting Bi and trivalent metal ions, investigate the influence of environmental factors on sensor response, and determine the implications of the findings for environmental and industrial monitoring applications. The research methodology involved the synthesis and characterization of macrocyclic ligands, immobilization of these ligands within a porous membrane matrix, preparation of synthetic samples containing Bi and trivalent metal ions, and analysis of sensor response using spectrophotometry. Key findings of the study include the high sensitivity of the sensors towards Bi ions, excellent selectivity towards trivalent metal ions, and optimal sensor response observed under neutral pH conditions. The long-term stability of the sensors over 21 days of continuous operation was also demonstrated. The calibration curve for Bi detection and determination of the limit of detection (LOD) and limit of quantification (LOQ) provide valuable metrics for assessing sensor performance. The implications of these findings extend to various environmental and industrial monitoring applications, where accurate detection and quantification of metal ions are crucial for safeguarding human health and environmental integrity.
