Calcination of Intercalated Talcite and Its Effect on the Adsorption of Abietate from Aqueous Solution

CODEN: JTEVAB

Abstract

Intercalated talcite was calcinated and its effect on the adsorption of abietate from aqueous solution was evaluated in this study. The amount of adsorbed abietate increased with increasing calcination temperature from 300°C to 500°C but decreased with increasing calcination temperature from 500°C to 600°C. Less abietate was adsorbed on anion-intercalated talcites than on their calcined products, except for sulfate anions. The calcined products of organic anion-intercalated talcites possessed a strong abietate-adsorption ability. The abietic acid existed in both colloidal and dissolved states. The regeneration ability of the abietate adsorbed by calcined talcite was poorer, and only about 20 % of the original adsorption amount was retained after five use cycles. The adsorption mechanism of abietate on the calcined talcites (i.e., the partial structure reconstruction of the calcined talcites) was proposed based on x-ray diffraction analysis. The calcined talcites had good long-term structural stability in the atmospheric medium.
