Square wave voltammetric determination of methyl parathion using ZrO2-nanoparticles modified carbon paste electrode

Preparation of a Magnetic Metal Organic Framework Composite and Its Application for the Detection of Methyl Parathion

“…26 A square wave voltammetric detection for MP with ZrO2-nanoparticles modified on a carbon paste electrode and an electrochemical sensor using an acetylene black-chitosan composite modified glassy carbon electrode has been developed. 27,28 The enhanced redox current of the MP was due to the nano structure of the composite and the enlarged effective electrode area. But in these electrochemical methods, the materials had to be modified on the electrode surface in advance.…”

Organophosphorus Pesticides Analysis

“…The electrochemical method of choice applied to OP pesticides analysis, considering the period 2005-2011, is square-wave voltammetry (Li and al., 2011;Parham and Rahbar, 2010;Sbaï et al, 2007;Tan et al, 2010;Wang and Li, 2008). It is recognized as a high sensitive regarding the detection of organic molecules.…”

“…The reported techniques include: nano-ZrO 2 modification of a carbon paste electrode (Parham and Rahbar, 2010), fabrication of ZrO 2 /Au nano-composite films on alumina substrates , electrodeposition of molecularly imprinted porous silicate (Tan et al, 2010) or of gold-sodium dodecylbenzene sulfonate nanoparticles onto a glassy carbon electrode (Li and al., 2011a), tetrasulfonated phtalocyanine electrodeposition combined with Nafion coating of carbon fibres (Sbaï et al, 2007), etc. ZrO 2 nanoparticles in particular, used as a selective sorbents for solid-phase extraction, demonstrate excellent performance in OP pesticides detection, because of their affinity toward the phosphate group on OP pesticide molecule (Parham and Rahbar, 2010;Wang and Li, 2008). The developed electrochemical methods are applied for OP pesticides determination in pears (Li and al., 2011;Tan et al, 2010), and in water samples (Parham and Rahbar, 2010).…”

Voltammetric Analysis of Pesticides

“…The working electrode consisted of a carbon paste electrode chemically modified by a synthesized Ca-hydroxyapatite. Many other unique applications of square wave voltammetry include the use of non-modified (Liu & Lin, 2005) and modified (Parham & Rahbar, 2010) carbon paste electrodes for the sensing of organophosphate pesticides, the quantification of pesticides in real water samples using ionomer clay-modified electrode (Zen et al, 1996) and even on non modified electrodes (Garrido et al, 1999(Garrido et al, , 2001. Some recent advances and applications of SWV were described, for which the stripping voltammetry was combined with solid-phase extraction often used in separation science (Gong et al, 2009(Gong et al, , 2010.…”
