Аннотация
The present paper describes the development of a new chemically modified carbon paste electrode based on azithromycin (AMC) that considered as a selective aluminium recognition agent in the carbon paste electrode (CPE). This electrode was fully characterized in terms of composition, response time, usable pH range and temperature. The electrode exhibited a Nernstian response for Al3+ ion over a concentration range from 7.0 × 10–6 to 1.0 × 10–2 mol L–1 with a slope of 21.3 ± 0.18 mV decade–1 and the limit of detection was 6.0 × 10–6 mol L−1. It had a response time of about 6 s. The proposed sensor possesses a very good selectivity with respect to a variety of other cations. Finally this modified electrode was applied for the determination of the concentration of Al3+ ion in different water samples and the obtained results were comparable with those obtained with atomic absorption spectrometer (AAS).
