The Origin of Hydrogen Generated from Formaldehyde in Basic Solutions
The isotopic composition of dihydrogen generated from formaldehyde in highly basic solutions has been investigated. It is shown that two pathways contribute to the generation of dihydrogen. In the f i s t pathway, one hydrogen atom originates from water and the other from formaldehyde. In the second pathway both hydrogen atoms originate from the methylene moiety of the formaldehyde. For product...
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 کاملFormaldehyde-releasers: relationship to formaldehyde contact allergy. Contact allergy to formaldehyde and inventory of formaldehyde-releasers.
This is one of series of review articles on formaldehyde and formaldehyde-releasers (others: formaldehyde in cosmetics, in clothes and in metalworking fluids and miscellaneous). Thirty-five chemicals were identified as being formaldehyde-releasers. Although a further seven are listed in the literature as formaldehyde-releasers, data are inadequate to consider them as such beyond doubt. Several ...
متن کاملFormaldehyde fixation.
The use of formaldehyde as a biological reagent occurred rather late in the history of histological methodology. The reason for this lay not in any lack of astuteness on the part of pathologists and histologists, but rather with the late development of formaldehyde manufacture by the chemical industry. While formaldehyde was discovered by Butlerov in 1859, practical aspects of the manufacture o...
متن کاملSorption of iodine by polyurethane and melamine-formaldehyde foams using iodine sublimation and iodine solutions
Iodine sorption by polyurethane (PU) and melamine-formaldehyde (MF) foams was studied using both iodine sublimation and iodine solutions with hexanes and toluene. In the sublimation process, the diffusion kinetics was investigated and the interaction between iodine and PU foams was characterized by DSC, TGA, Raman spectroscopy and electrical conductivity measurements. In the solution process, t...
