my.unimap-695822021-02-08T03:57:32Z Adsorption isotherm characteristics of calcium carbonate microparticles obtained from barred fish (Scomberomorus spp.) bone using two-parameter multilayer adsorption models Asep Bayu Dani Nandiyanto Thyta Medina Salsabila Erlangga Ghina Mufidah Sri Anggraeni Roil, Bilad Jumril, Yunas nandiyanto@upi.edu Adsorption isotherm Calcium carbonate Fish bone Hill-de Boer and Langmuir. Link to publisher's homepage at http://ijneam.unimap.edu.my Adsorption isotherm of calcium carbonate microparticles prepared from calcined barred fish (Scomberomorus spp.) bone at temperature of 600C was investigated. The experiments were done by testing adsorption ability of the prepared calcium carbonate microparticles (with sizes of 100, 125, and 250 μm) for adsorbing curcumin molecules (extracted from turmeric) in aqueous solution in the batch-type adsorption reactor. The adsorption results were compared with several two-parameter multilayer adsorption models (i.e. Langmuir, Freundlich, Temkin, Dubinin-Radushkevich, Flory-Huggins, Fowler–Guggenheim, and Hillde Boer isotherm models). Hill-de Boer model is the best model in this study. The adsorption process takes place on a multilayer surface, and the adsorbent-adsorbate interaction is a physical adsorption (which confirmed and is good agreement with the results from Hill-de Boer models and suitable with Dubinin-Radushkevich, Langmuir, and Temkin models). Adsorption is carried out at different locations energetically under endothermic processes. The Gibbs free energy confirms that the adsorption is spontaneous. The results also confirmed that the smaller adsorbent had a direct impact on the increase in adsorption capacity (due to the large surface area). From all samples, the particle size of 125 μm has a good performance. Particles with smaller size (less than 125 μm) are less optimal in the adsorption process because some aggregation between particles occurs to become larger particles. 2021-02-08T03:57:32Z 2021-02-08T03:57:32Z 2020-12 Article International Journal of Nanoelectronics and Materials, vol.13(Special Issue), 2020, pages 45-58 1985-5761 (Printed) 1997-4434 (Online) http://dspace.unimap.edu.my:80/xmlui/handle/123456789/69582 en NANOSYM, 2019; Universiti Malaysia Perlis (UniMAP) |
