This batch and column kinetics study of arsenic removal utilized copper-impregnated natural mineral tufa (T-Cu(A-C)) under three ranges of particle size. Non-competitive kinetic data fitted by the Weber-Morris model and the single resistance mass transfer model, i.e., mass transfer coefficient k(f)a and diffusion coefficient (D-eff) determination, defined intra-particle diffusion as the dominating rate controlling step. Kinetic activation parameters, derived from pseudo-second-order rate constants, showed low dependence on adsorbent geometry/morphology and porosity, while the diffusivity of the pores was significant to removal efficacy. The results of competitive arsenic adsorption in a multi-component system of phosphate, chromate, or silicate showed effective arsenic removal using T-Cu adsorbents. The high adsorption rate-pseudo-second-order constants in the range 0.509-0.789gmg(-1)min(-1) for As(V) and 0.304-0.532gmg(1)min(1) for As(III)-justified further application T-Cu(A-C) in a ...flow system. The fixed-bed column adsorption data was fitted using empirical Bohart-Adams, Yoon-Nelson, Thomas, and dose-response models to indicate capacities and breakthrough time dependence on arsenic influent concentration and the flow rate. Pore surface diffusion modeling (PSDM), following bed-column testing, further determined adsorbent capacities and mass transport under applied hydraulic loading rates.
