Abstract
Various copper loaded ZSM-5 zeolites was prepared and characterized in details of their optical, structural, morphological, elemental properties by various conventional methods. The Cu-ZSM-5 zeolites were deposited on silver electrode to result in a chemical sensor that has a fast response to selective 3-methoxyphenol (3-MP) in buffer phase. Analytical sensor parameters such as sensitivity, detection limit, reproducibility, selectivity, repeatability, linear dynamic range, and electrochemical performances were investigated in details with the Cu-ZSM-5 zeolites fabricated sensors. The calibration plot is linear over the large 3-MP concentration range. The sensitivity and detection limit of target 3-MP is calculated as similar to 13.232 mu A cm(-2) mu M-1 and 0.083 +/- 0.002 nM (at a signal-to-noise-ratio, SNR of 3) respectively. With such excellent features as wide linear dynamic range, higher sensitivity, good stability, lowest detection limit, excellent selectivity, the developed sensor provides a new strategy for determination of 3-MP in biomedical and environmental sample with satisfactory results.
