Abstract

Isotherm adsorption of calcium carbonate microparticles obtained from tuna fish bone was evaluated. The adsorption process was carried out through a batch process under a constant pH condition and room temperature. To ensure the isotherm adsorption, three sizes of calcium carbonate (i.e. 99, 125, and 250 um) were analyzed using curcumin solution as a model of adsorbate solution. The results of the isotherm adsorption analysis were compared with the Langmuir, Temkin, Freundlich, and Dubinin-Radushkevich models. To confirm the physicochemical characteristics of the prepared calcium carbonate, characterization was carried out using a Digital Microscope observation, sieve test, and Fourier transform infrared measurement. The results of the adsorption analysis showed that the isotherm adsorption profiles for all sizes between 99 and 250 um were identical to the Langmuir isotherm model, confirmed that the process was considered as a monolayer adsorption. Adsorbent size plays an important role in the adsorption process. Particle size of calcium carbonate 125 μm shows good performance in this study.

Keywords: calcium carbonate, adsorption isotherm, fish bone, Langmuir, Freundlich, Temkin, Dubinin-Radushkevich.
