Occurrence of soluble organic compounds in thermal waters by ion trap mass detection

摘要: Abstract Thermal waters can be regarded as worth developing because of their human health implications and, if thermal tourism is promoted, importance to the local economy. Galicia, in North-West Spain, has numerous sources spread all over region. They have been used for therapeutic purposes since Roman times. Ourense, with 82 (9 spas), becoming one richest Spanish provinces hydromineral and resources. In this work, most representative springs from city Ourense – Outariz, Chavasqueira, Tinteiro As Burgas were analysed order identify presence several chemical classes soluble organic compounds responsible biological activity. The studied are hyperthermal, temperatures ranged between 45 66 °C. Different extraction techniques, liquid–liquid (LLE), solid phase (SPE) micro-extraction (SPME), combined gas chromatography–electron impact ion trap mass spectrometry (GC–(EI)ITMS) cover a wide variety compounds. characteristic families extractable detected thoroughly discussed. Most substances belonging phenol, aldehyde, esther, ketone, elemental sulphur groups occur samples. Large amounts found spring, providing water beneficial clinical effects.
