Isotherm Models of Heavy Metal Sorption onto Zinc-tricarboxylic

C. Kowsura, B. Pangkumhang, P. Jutaporn, and V. Tanboonchuy
Abstract—Zinc-tricarboxylic (Zn-BTC) consists of Zinc Acetate Dihydrate (Zn(CH3COO)2∙2H2O) and 1,3,5 Benzenetricarboxylic Acid (H3BTC), a well-known metal-organic framework (MOFs). It was synthesized by hydrothermal process. This study was established to analyze the capability of Pb(II) and Cu(II) adsorption onto Zn-BTC synthesized. The adsorption isotherms of Pb(II) and Cu(II) were compared to Langmuir, Freundlich, and Dubinin-Radushkevitch models. The results show greater correlation coefficient between these two adsorption isotherms and Langmuir model. The maximum adsorption capacities of the synthesized Zn-BTC were 416.7 mg/g for Pb(II) and 85.5 mg/g for Cu.

Index Terms—Zinc-tricarboxylic, MOFs, sorption, heavy metal, Pb(II), Cu(II).
