Description
2,4-Dichlorophenol (2,4-DCP) is found to have a prevalent application in synthesizing many industrial materials, meanwhile leading to toxicological effects on human health and aquatic life. This work demonstrates the construction of a highly responsive electrochemical sensing platform for 2,4-DCP, based on ruthenium phosphate electrodeposited over poly-(3,4 diaminobenzoic acid)-loaded carbon fiber paper (Ru-Pi/PDABA/CFP). Surface modification of the conducting polymer with Ru-Pi improves electrocatalytic performance by enhancing available electrocatalytic sites and rapid charge transmission channels. The developed electrode was characterized using XRD, XPS, and SEM studies to substantiate the formation of Ru-Pi/PDABA/CFP hybrid material, and electrochemical studies further evidence the improved electrochemical performance upon electrode modification. Cyclic voltammetric studies showcased 2-fold enhanced catalytic activity of Ru-Pi/PDABA/CFP compared to the bare CFP. Differential pulse voltammetric outcome corroborated outstanding electroanalytical metrics towards 2,4-DCP, unveiling an appreciably minimal limit of detection (LOD) of 1.47 nM and a low quantification boundary (LOQ) of 4.37 nM in a wide concentration-response linearity of 5 450 nM. The interferences from foreign substances produced only negligible signal modulations (<4.6 %) on the current amplitude of 2,4-DCP, validating the sensor's excellent selectivity towards the target analyte. Further, the application of Ru-Pi/PDABA/CFP was extended for the 2,4-DCP assay in actual tap and lake water samples. 2025
