Ion-molecule reactions and chemical composition of emanated from herculane Spa geothermal sources

Abstract

The paper presents a chemical composition analysis of the gases emanated from geothermal sources in the Herculane Spa area (Romania). The upper homologues of methane have been identified in these gases. An ion-molecule reaction mechanism could be implicated in the formation of the upper homologues of methane. The CH 4+ ions that appear under the action of radiation are the starting point of these reactions. The presence of hydrogen in the emanated gases may be also a result of these reactions. © 2008 by the authors; licensee Molecular Diversity Preservation International.
