BiO/ZnO nanocomposite: Synthesis, characterizations and its application in electrochemical detection of balofloxacin as an anti-biotic drug.

In the present work, a chemically modified electrode has been fabricated utilizing BiO/ZnO nanocomposite. The nanocomposite was synthesized by simple sonochemical method and characterized for its structural and morphological properties by using XRD, FESEM, EDAX, HRTEM and XPS techniques. The results clearly indicated co-existence of BiO and ZnO in the nanocomposite with chemical interaction between them.

Single-step green route synthesis of Au/Ag bimetallic nanoparticles using clove buds extract: Enhancement in antioxidant bio-efficacy and catalytic activity.

In present work, we demonstrate a single step environmentally benign approach to synthesize Au/Ag bimetallic nanoparticles (BMNPs) using aqueous extract of Clove buds for the first time. Clove bud's (CB) extract has proficiency to act as a reducing and stabilizing agent for the formation of Au/Ag BMNPs. In presence of extract, Au and Ag are reduced competitively within same solution and produce Au/Ag alloy NPs.

Voltammetric trace determination of mercury using plant refuse modified carbon paste electrodes.

Citrus limon peel (kitchen waste) and Leucaena leucocephala seeds (agricultural waste) were used as a modifier for fabrication of modified carbon paste electrode for determination of mercury in aqueous sample using differential pulse anodic stripping voltammetry. Mercury was adsorbed on electrode surface at open circuit and anodic stripping voltammetric scan was run from -0.5 to 0.

Nanocellulosic fiber-modified carbon paste electrode for ultra trace determination of Cd (II) and Pb (II) in aqueous solution.

In recent years, increasing awareness of the environmental impact of heavy metals has prompted a demand for monitoring and decontaminating industrial wastes prior to discharging into natural water bodies. This paper describes the preparation and electrochemical application of carbon paste electrode modified with nanocellulosic fibers for the determination of cadmium and lead in water samples using anodic stripping voltammetry. First, cadmium and lead were adsorbed on the carbon paste electrode surface at open circuit potential, followed by anodic stripping voltammetric scan from -1 to 0 V.

Potentiometric studies of metal-biomass interaction with reference to bioaccumulation.

An electrochemical experiment (Linear Polarization) has been carried out to illustrate the binding of Cd2+ and Pb2+ by Moringa oleifera seed powder. Reduction in Open Circuit Potential (OCP) value indicates a decrease in the metal concentration due to the binding of metal ions at the active sites of biomass. Maximum sorption of Cd2+ and Pb2+ was calculated by the use of Nernst equation and found to be 81.
