Silver nanoparticles built-in chitosan modified glassy carbon electrode for anodic stripping analysis of As(III) and its removal from water

Electrochemical determination of inorganic mercury and arsenic—A review

“…Platinum nanoparticles on screen printed electrodes (SPE) and boron doped diamond (BDD) electrodes were employed with detection limit of 5.68µg/L(Sanllorente-Méndez et al 2009) and 0.5µg/L(Hrapovic et al 2007) respectively. A detection limit of 0.1µg/L was achieved with platinum nanotube-array electrode(Xu et al 2008) Prakash et al, (2012). prepared silver nanoparticles-chitosan modified glassy carbon electrode and reported a detection limit of 1.2µg/L(Prakash et al 2012).…”

Boron doped diamond (BDD) electrode is considered a suitable working electrode as it has broad potential window, lower capacitance and good mechanical strength.…”

Preparation and characterization of collagen/chitosan composites with silver nanoparticles

“…Film with the addition of silver nanoparticles has a greater value of surface free energy and its value is 29.6 mJ/m 2 . Such a difference is caused by silver nanoparticles, because metallic nanoparticles provide a higher surface free energy of samples . For samples made of collagen/chitosan, the dispersive component of surface free energy is 22.48 mJ/m 2 and polar component is 2.77 mJ/m 2 .…”

Bismuth–silver bimetallic nanosensor application for the voltammetric analysis of dust and soil samples

“…The purpose of this investigation is to determine which of these electrolytes will give the largest peak current, the best shape of peak and the lowest background current [43]. between À1.4 V to +0.8 V (vs. Ag/AgCl) at a scan rate of 60 mV s À1 [9,35]. Weak redox activity is observed at the bare glassy carbon electrode.…”

“…A 2.5 mg of bismuth-silver (Bi-Ag) bimetallic nanoparticles were dispersed through ultrasonic vibration in 50 mL solution of deionised water to form a suspension. A defined quantity of the suspension was applied to a clean surface of GCE and dried at room temperature to get a thin film on GCE surface [29,[34][35][36][37]. After each voltammetric cycle the cleaning of the Bi-Ag bimetallic nanosensor was carried out by holding the potential of the electrode at +1.0 V. Traces of the remaining DMG complexes on the electrode surface were reduced and quickly desorbed at this potential.…”
