Abstract
Bismuth film modified and chemically activated carbon micro-thread electrodes were investigated for the simultaneous determination of Cd(II) and Pb(II) using square wave anodic stripping voltammetry. The carbon thread electrode was characterised using both surface and electrochemical techniques. Electrochemical impedance spectroscopy (EIS) studies demonstrated that the H2SO4/IPA-treated carbon thread electrode showed a much improved resistance response (Rct=23 Ω) compared to the IPA-untreated carbon thread (Rct=8317 Ω). Furthermore, parameters such as the effect of deposition potential, deposition time and Bi(III) concentration were explored using square wave voltammetry. Detection limits (S/N=3) for Cd(II) and Pb(II) were found to be 1.08 µg L−1 and 0.87 µg L−1, respectively and response was found to be linear over the range 5–110 µg L−1. The proposed Bi/IPA-treated carbon thread electrode exhibited a high selectivity towards Cd(II) and Pb(II) even in the presence of a range of heavy metals and is capable of repetitive and reproducible measurements, being attributed to the high surface area, geometry and electrode treatment characteristics. The proposed metal ion sensor was employed to determine cadmium and lead in river water samples and % RSD was found to be 5.46 % and 5.93 % for Cd(II) and Pb(II) respectively (n=3). Such facile sensing components favour the development of cost effective portable devices for environmental sample analysis and electrochemical applications.

High surface area activated carbon fibers (ACF) have been prepared from bamboo by steam activation after liquefaction and curing. The influences of activation temperature on the microstructure, surface area and porosity were investigated. The results showed that ACF from bamboo at 850 °C have the maximum iodine and methylene blue adsorption values. Aside from the graphitic carbon, phenolic and carbonyl groups were the predominant functions on the surface of activated carbon fiber from bamboo. Th...

Commercially available activated carbon fibers (ACFs) were modified further by a chemical activation method to obtain superior CO2 adsorption capacity. The relationship between the pore structure of the modified ACF and the CO2 adsorption behaviors was investigated. Chemical activation (with KOH at a fixed activation temperature of 900 °C for 1 h and various KOH/ACF weight ratios ranging from 1 to 4) of ACF increased the total pore volume and specific surface area to 1.124 cm3 g−1 (KOH/ACF weigh...

Abstract Reduced graphene oxide (RGO) is synthesized and added in situ into the reaction system of polyaniline (PANI) electrodeposition using activated carbon cloth (ACC) as the substrate. The effect of RGO on the morphology, structure, and electrochemical properties of the ACC/PANI composite is investigated. A more compact and uniform layer of PANI film is observed via scanning electronic microscopy after the addition of RGO. Raman spectroscopy shows that RGO has been simultaneously deposited w...

The removal of some of pollutants including catechol, 3-methylcatechol, 3-methoxycatechol, and 2,3-dihydroxybenzoic acid by adsorption onto activated carbon cloth (ACC) at 35.0 ± 0.1°C was investigated. The equilibrium experimental data were fitted to Langmuir, Freundlich, Temkin, Langmuir-Freundlich, and Redlich-Peterson isotherms. Also the kinetic experimental data were fitted to the pseudo-first-order and pseudo-second-order kinetic models. It was found that the pseudo-second-order model desc...

Abstract In this paper, a novel automatic approach for the speciation of inorganic mercury (Hg 2+ ), methylmercury (MeHg + ) and ethylmercury (EtHg + ) using multisyringe chromatography (MSC) coupled to cold-vapor atomic fluorescence spectrometry (CV/AFS) was developed. For the first time, the separation of mercury species was accomplished on a RP C18 monolithic column using a multi-isocratic elution program. The elution protocol involved the use of 0.005% 2-mercapthoethanol in 240 mM ammonium a...
