- Abstract
A silicon carbide nanoparticle-coated glassy carbon electrode (SiCNPs-GCE) was employed for electrochemical determination of Quinalphos (QNP) using different electroanalytical techniques. QNP showed an enhancement in the reduction peak current at SiCNPs modified GCE in pH 7.0 (BR Buffer). The peak current was found to be linear with the QNP concentration in the range from 6.69×10−9 to 1.34×10−6 M ( r=0.995) with detection limit of 1.34×10−9 M ( S/ N=3). The developed sensor (SiCNPs-GCE) was employed for QNP determination in tap water, lake water, soil, mango as well as in biological samples.
