A novel and effective method for immobilization of active ruthenium (II) bipyridine complex on screen printed gold electrode surface was developed simultaneous determination Cd Pb in an environmental water sample. The electrostatic interaction between negatively charged graphene oxide (GO) or citrate-capped nanoparticles (AuNPs) positively ([Ru(bpy)3]2+) studied with the incorporation cation exchanging Nafion polymer, which enhanced electron transfer rate, reduced interference caused by...
This study presents a simple, low-cost, sensitive and environmentally friendly approach for the simultaneous electrochemical determination of lead cadmium based on commercial screen-printed gold electrode (SPGE) with Nafion an in situ bismuth film. The developed sensor was coated polymer to reduce interference enhance stability reproducibility working film increase sensitivity achieve low detection limit. Electrochemical properties were investigated using anodic stripping square voltammetry....
Recently, non-steroidal anti-inflammatory drugs (NSAIDs) have been increasingly used in humans and animals.
In this study, an in situ synthesis approach based on electrochemical reduction and ion exchange was employed to detect carbaryl species using a disposable, screen-printed carbon electrode fabricated with nanocomposite materials. Reduced graphene oxide (rGO) used create larger surface more active sites. Gold nanoparticles (AuNPs,) were incorporated accelerate electron transfer enhance sensitivity. A cation Nafion polymer enable the adhesion of rGO AuNPs speed up exchange. Cyclic voltammetry...
A simple, rapid method using CE and microchip electrophoresis with C
Abstract Paracetamol (PAC) is one of the most extensively used analgesics and antipyretic drugs to treat mild moderate pain. P‐aminophenol (PAP), main hydrolytic degradation product PAC, can be found in environmental water. Recently, CE has been developed for detection a wide variety chemical substances. The purpose this study develop simple fast method separation PAC its hydrolysis PAP using microchip electrophoresis with capacitively coupled contactless conductivity detection....
Polychlorinated biphenyls (PCBs) have been found in soil, which has typically the result of industrial pollution past two decades. Although they are banned, PCBs can still be soils and other environmental media. For this reason, it is critical to develop an analytical method that reliably identify monitor their sources. This study describes a gas chromatography with mass spectrometry (GC-MS) technique, was used detect soil samples by using fast extraction method. Using QuEChERS (quick, easy,...
PCBs (polychlorinated biphenyls) are a very large group of organic compounds that have between two and ten chlorine atoms attached to the biphenyl. These an acute impact as environmental pollutants, causing cancer other adverse health effects in humans. It is therefore imperative develop techniques for cost-effective detection at low concentrations ecosystems. In this paper, novel label-free, indirect, competitive electrochemical immunosensor was first developed with PCB-BSA conjugate. shown...
