Chemical inferences drawn from volcanic pumice
Özet
The idea to conduct this study came out with the purpose of responding to two questions concerning the
Kula Geopark. The questions were as follows: how the wettability of the natural pumice sample with
spongy structure taken from this site is and how it can be altered. With this end in view, firstly the pumice
samples were characterized by X-ray Fluorescence Spectroscopy, Fourier Transform Infrared
Spectroscopy and Scanning Electron Microscopy analyses. Next, after observing super hydrophilic nature
of the pumice with porous structure containing various metal oxides, the samples were coated with copper
stearate dispersion using a spraying method. And then the wettability properties of the copper stearate treated samples were determined via contact angles. Given the data obtained, the wettability phenomena
of these samples were discussed in terms of wettability models.
