Usage

General Description

BIS(2-CHLOROETHYL)DISULPHIDE, also known as sulfur mustard, is a highly toxic and corrosive chemical compound that has been used as a chemical warfare agent. It is a vesicant, meaning it causes severe skin, eye, and lung irritation upon contact, and can also lead to blistering and necrosis. Exposure to BIS(2-CHLOROETHYL)DISULPHIDE can result in respiratory problems, eye damage, and long-term health effects such as cancer and birth defects. It is classified as a Schedule 1 controlled substance under the Chemical Weapons Convention due to its extreme toxicity and the devastating effects it can have on human health. Additionally, it has been banned for use in warfare by the Geneva Protocol and the Chemical Weapons Convention.

Photo-degradation of yperite over V, Fe and Mn-doped titania-silica photocatalysts

The photocatalytic decomposition of yperite (bis(2-chloroethyl)sulfide), a chemical warfare agent, was achieved by using titania-silica catalysts doped with several transition metal ions. The preparation of these catalysts was achieved by impregnation of a titania-silica mixed oxide previously synthesized using a sol-gel route with salts of the doping elements (vanadium, iron, manganese). The above catalysts were characterized using several spectroscopic techniques: FTIR, Raman, DR-UV-Vis, and XPS. The band gap energy was measured for each photocatalytic system. The reaction was carried out in two different types of reactors, i.e. naturally aerated and a closed quartz tube aerated under a constant flow, and using two types of irradiation, UV-Vis and Vis. The investigated systems proved to be extremely active, leading to an almost complete degradation of yperite in 2 h of irradiation. An excellent correlation between the photocatalytic performances and the band gap has been found. Based on the characterization data and on the temporal evolution of the reaction products, a reaction mechanism has been suggested. This mechanism considers two distinct pathways for the decomposition of yperite, namely the C-S bond cleavage and the S oxidation.
