摘要

A simple and greener electrochemical sensing platform towards nitrite measurement using amine modified Zr-terephthalate and MWCNTs has been demonstrated. The characterization of the composite material has been carried out using spectroscopic and voltammetric techniques. The composite material overcomes the inherent drawbacks of MOFs like lower conductivity and stability in aqueous medium. The MWCNTs/Zr-ATA composite modified electrode showed better electrocatalytic activity in nitrite quantification with good linearity in the concentration range 2-440 mu M with detection limit 0.22 mu M and sensitivity of 0.657 mu A mu M-1 cm(-2). The fabricated electrode has been applied to quantify nitrite from root nodule samples.
