Modified electrosynthetic sample introduction technique is a reliable means of solving the problem of high sensitivity analysis of trace arsenite. This article attempts to achieve selective electroreduction of As through the construction of electrode surfaces with different structures and materials from the perspective of interface reactions. Among the four transition metal modifiers, the iron modified nickel foam electrode with nano-flower structure documented higher efficiency in inducing arsenic reduction and better species selectivity.

The transformation of toxic arsine (AsH) gas into valuable elemental arsenic (As) from industrial exhaust gases is important for achieving sustainable development goals. Although advanced arsenic removal catalysts can improve the removal efficiency of AsH, toxic arsenic oxides generated during this process have not received adequate attention. In light of this, a novel approach for obtaining stable As products was proposed by performing controlled moderate oxidation.

In this study, three kinds of iron minerals, ferrihydrite, hematite, and goethite, were prepared by a simple coprecipitation method for the adsorption and removal of phenylarsonic acid (PAA). The adsorption of PAA was explored, and the influences of ambient temperature, pH, and co-existing anions on adsorption were evaluated. The experimental results show that rapid adsorption of PAA occurs within 180 min in the presence of iron minerals, and the adsorption process conforms to a pseudo-second-order kinetic model.

Due to the high-acidic arsenic-containing wastewater pollution greatly threatening human health and ecological safety, a simple and efficient method for reducing arsenic was proposed in this paper to solve this problem. By using potassium borohydride (KBH) as a reducing agent, the soluble arsenic was converted into the gaseous arsine (AsH) or solid arsenic (As) to achieve the purpose of removing arsenic in wastewater. By exploring the reaction kinetics of the arsenic removal process, it was found that the fast reaction stage (0-2 min) conformed to pseudo-first-order kinetics.

Article Synopsis
- A density functional theory (DFT)-based study examined the effectiveness of chlorobenzene in detecting toxic gases like hydrogen cyanide, arsine, and phosgene using a single-electron transistor (SET).
- The research analyzed how these gas molecules interact with chlorobenzene, focusing on their charge density and molecular properties.
- Findings revealed varying recovery times for gas detection, with chlorobenzene-based SET showing strong adsorption characteristics, especially for phosgene, indicating a promising option for gas sensing applications.
