Formaldehyde degradation by catalytic oxidation.
Formaldehyde used for the disinfection of a laminar-flow biological safety cabinet was oxidatively degraded by using a catalyst. This technique reduced the formaldehyde concentration in the cabinet from about 5,000 to about 45 mg/m3 in 8 h. This technique should prove useful in other applications.
متن کاملAdvanced oxidation of formaldehyde in the aqueous solutions using UVC/S2O82- process: Degradation and mineralization
Background: As a human carcinogen, formaldehyde is a toxic chemical imposing adverse effects on public health and environment. Due to its high reactivity, colorless nature, sustainability, purity in commercial forms, and low prices, the production and consumption of this compound has expanded vastly in industries. Methods: In this study, a UVC photoreactor with a total volume of 120 mL was us...
متن کاملSelective Oxidation of Dimethylether to Formaldehyde on SmallMolybdenum Oxide Domains
MoOx species dispersed as small domains on Al2O3, ZrO2, and SnO2 catalyze the oxidative conversion of dimethylether to formaldehyde with high primary selectivity (80–98% HCHO, CH3OH-free basis) at low temperatures (500–550 K). The reaction appears to proceed via redox cycles using lattice oxygen and turnover rates increase with the size and reducibility of MoOx domains. Dimethylether conversion...
متن کاملFormaldehyde production from isoprene oxidation across NOx regimes.
The chemical link between isoprene and formaldehyde (HCHO) is a strong, non-linear function of NOx (= NO + NO2). This relationship is a linchpin for top-down isoprene emission inventory verification from orbital HCHO column observations. It is also a benchmark for overall photochemical mechanism performance with regard to VOC oxidation. Using a comprehensive suite of airborne in situ observatio...
متن کاملMultiple formaldehyde oxidation/detoxification pathways in Burkholderia fungorum LB400.
Burkholderia species are free-living bacteria with a versatile metabolic lifestyle. The genome of B. fungorum LB400 is predicted to encode three different pathways for formaldehyde oxidation: an NAD-linked, glutathione (GSH)-independent formaldehyde dehydrogenase; an NAD-linked, GSH-dependent formaldehyde oxidation system; and a tetrahydromethanopterin-methanofuran-dependent formaldehyde oxidat...
