The Polyperfluoromethylisopropyl Ether used as a surface tensiometry tool for non-invasive quality assessment of peloids (TVS mud index®): An overview

Abstract

Background Surface tensiometry consented to characterize the surface free energy of geomaterials in an integrated and non-destructive way. A new surface tensiometry tool, based on the contact angle measurement of Polyperfluoromethylisopropyl Ether (TVS mud index), has thus developed in the early 2000s. The TVS mud index was for the first time employed from 2005 to 2010 for surface tensiometry characterization of peloids for pelotherapy from Abano Terme and Montegrotto Terme (Pa-dova, Italy). We aim to report the surface tensiometry application in the thermal field, and show the potentialities of TVS mud index as a marker for the non invasive quality control of the peloids and their maturation process. Methods The determination of the typical chemical-mineralogical characteristics of a Euganean Thermal Mud (ETM) and their surface tensiometry allowed us to demonstrate the link between the chemical data from X-ray fluorescence (XRF) analysis and they performed using a tensiometer to assess the quality of the peloid and its biological maturation process. Results The liquid test Polyperfluoromethylisopropyl Ether-based demonstrated the link between variations in volume elements and surface free energy of muddy matrices. The research results here showed that the TVS mud index is linked to the chemical pattern of peloids. Conclusions The research work implemented in the period 2005-2010 showed the potentialities of surface tensiometry in the assessment of peloids for pelotherapy using Polyperfluoromethylisopropyl Ether as a liquid test.
