Surface| Резюме: | IR-spectroscopy has been applied to studies on interaction of acetic acid and tartaric acid with silica-containing minerals, namely analcime and trepel of various particle size obtained due to industrial crushing. After contact of mentioned acids with minerals, a transformation takes place of carbonate admixtures into soluble acetic salts in the case of acetic acid whereas tartaric acid converts them into not readily soluble calcium tartrate and soluble iron salts. Investigation of tartaric acid adsorption on analcime, trepe,l and ultrafine silica allowed us to classify the results according to shape of adsorption isotherms and also to find out correlations between characteristics of acid-adsorbent interaction, nature of this process, and particle size. |
