Modeling of Adsorption of Bi(III) from Nitrate Medium by Impregnated Resin D2EHPA/XAD-1180

Abstract

ABSTRACT

A unique, inexpensive, and abundantly available adsorbent: composite of synthesized silver nanoparticles (AgNPs) and banana leaves powder (BLP)

“…The first linear segment describes the external surface adsorption. The second linear segment describes the second stage in which the Zn (II), Pb (II), and Fe (III) ions are gradually adsorbed within the pores of BLP/AgNPs particles The rate constants of the two stages k p1 and k p2 are presented in Table 5 , Additionally, the plot exhibited deviation from the origin which refers to that the intraparticle diffusion is not the only rate-limiting step and Zn(II), Pb(II), and Fe(III) ions adsorption process may be controlled by other kinetic models [ 59 , 60 ].…”
