Abstract:
Oxalic acid (OA) is a crucial compound associated with many biological processes in organisms. High
level of OA is related to an increased risk of several diseases such as kidney stones, urinary tract infections
and hypocalcemia, due to the formation of calcium oxalate crystals. Therefore, the development of a reliable
and sensitive sensor for frequent monitoring of OA concentration is required. In this work, a low-cost and
portable electrochemical sensor based on screen-printed graphene electrode (SPGE) modified with Cu-Pd
bimetallic nanoparticles and molecularly imprinted polymer (MIP) was developed for the detection of OA
with enhanced sensitivity and selectivity. The Cu-Pd modified SPGE, simply prepared by electrodeposition,
was tethered with MIP via electropolymerization process by cyclic voltammetry (CV) using ortho-
phenylenediamine as monomer to obtain the MIP/Cu-Pd/SPGE sensor. The analytical performance of this
sensor was investigated by square wave voltammetry (SWV). Under optimal conditions, the MIP/Cu-
Pd/SPGE illustrated a linear relationship ranging from 10 to 800 JM with limits of detection (LOD) and
quantification (LOQ) of 2.18 and 7.27 MM, respectively. Moreover, the proposed MIP/Cu-Pd/SPGE sensor
could be utilized for OA determination in artificial urine with 9recoveries ranging from 97.78 to 104.33.
