This paper presents the application of zinc/aluminium-layered double hydroxide-quinclorac (Zn/Al-LDH-QC) as a modifier multiwalled carbon nanotubes (MWCNT) paste electrode for determination bisphenol A (BPA). The Zn/Al-LDH-QC/MWCNT morphology was examined by transmission electron microscope and scanning microscope. Electrochemical impedance spectroscopy utilized to investigate interfacial properties. electrochemical responses modified towards BPA were thoroughly evaluated using square-wave...
In this work, a novel electrochemical sensor was developed by electron-withdrawing substituent modification of 1-phenyl-3-methyl-4-(4-fluorobenzoyl)-5-pyrazolone on graphene-modified glassy carbon electrode (HPMpFP-graphene/GCE) for glucose detection. The results characterizations using scanning electron microscope, Fourier transform infrared spectroscopy, Raman and nuclear magnetic resonance spectroscopy showed the successful fabrication HPMpFP-graphene nanocomposite, which served as an...
Recent trends in electrochemical sensors based on conducting polymer functionalized graphene for the detection of pollutants water are highlighted this review. Graphene has been subject a lot scientific research to be composited with polymers. Researchers interested and its variants because they have good qualities, like electrical mechanical properties very high surface area.

Bispyribac (BP) anions have been successfully intercalated in the interlayer region of zinc hydroxide nitrate (ZHN) presence sodium dodecylsulphate (SDS) surfactant. The physicochemical properties intercalation compound ZHN–SDS–BP characterised herein with different instrumental techniques. BP and SDS is clearly reflected PXRD analysis, based on appearance symmetrical, sharp intense peaks at lower 2θ a basal spacing 28.2–28.6 Å. thermal studies show that nanocomposite has better stability...
Over a decade, the Malaysia National Poison Centre found that 40% of pesticide poisoning cases may be linked to excessive paraquat (PQ) in water, soil, or food, underscoring widespread impact on public health and emphasising importance detecting even trace amounts PQ residues environment. Thus, this study presents novel electrochemical sensor based multiwalled carbon nanotubes (MWCNTs) reinforced cadmium sulphide co-anchoring graphitic nitride (CdS/g-C3N4) nanocomposites for detection. The...
Square wave voltammetry, cyclic chronocoulometry, and electrochemical impedance spectroscopy were employed to assess ascorbic acid's behavior in multiwalled carbon nanotubes (MWCNTs)/carbon paste electrode (CPE) modified by 1-phenyl-3-methyl-4-metafluorobenzoyl-5-pyrazolone (HPMmFBP). The irreversible oxidation peak appeared at approximately 0.5 V. shifting of the potential pH range 6.0–8.4 showed involvement protons acid oxidation. Moreover, with scan rate 0.07–0.4 V/s confirmed that...
The construction and performance characteristics of polymeric membrane electrodes based on 2,6-diacetylpyridine-(1R)-(-)-fenchone diazine ligand (A) for quantification copper ions, are described. Effect various plasticizers anion excluder, sodium tetraphenylborate (NaTPB) was studied improved observed at several instances. Best obtained with the having following composition; A (7): PVC (50): TMDP (86): NaTPB (1). exhibits Nernstian response in concentration range 1.0×10−5 to 1.0×10−1 M a...
The environmental pollution that results from the excessive usage of pesticides has been threatening communities for decades. In this study, carboxymethyl cellulose (CMC) is proposed as a coating agent to encapsulate zinc hydroxide nitrate–sodium dodecylsulphate–imidacloprid (ZHN–SDS–IC) implementation controlled release formulation (CRF) in pesticide. physicochemical properties ZHN–SDS–IC–CMC were characterised so their crystallinity, thermal behaviour and surface morphology could be...
