Hydrophilic properties of aged soot
Websoot aged by exposure to OH and O 3 in the presence of UV lamp radiation at RH 60%,as measured with a QCM. Aged (oxidized) soot exhibited enhanced hydrophilicity and … WebWater uptake on hygroscopic soot takes place by the absorption mechanism: it significantly exceeds the formation of many surface layers. If soot particles are made mostly from elemental carbon and/or are covered by a water-insoluble organic layer, they are classified as non-hygroscopic.
