Development of a mercury optical sensor based on immobilization of 4-(2-pyridylazo)-resorcinol on a triacetylcellulose membrane
A new optical sensor for mercury(II) ions is developed based on immobilization of 4-(2-pyridylazo)-resorcinol (PAR) on a triacetylcellulose membrane. Chemical binding of Hg 2+ ions in solution with a PAR immobilized on the triacetylcellulose surface could be monitored spectrophotometrically at 525 n...

| description | A new optical sensor for mercury(II) ions is developed based on immobilization of 4-(2-pyridylazo)-resorcinol (PAR) on a triacetylcellulose membrane. Chemical binding of Hg
2+ ions in solution with a PAR immobilized on the triacetylcellulose surface could be monitored spectrophotometrically at 525
nm. The optode shows excellent response over a wide concentration range of 5–3360
μM Hg(II) with a limit of detection of 1.5
μM Hg(II). The influence of factors responsible for the improved sensitivity of the sensor were studied and identified. The response time of the optode was 20
min for a stable solution, and was 15
min for a stirrer solution. The influence of potential interfering ions on the determination of 5
