Effect of Batch Factor on a Binary Ion Exchange Equilibrium [PDF]

open access: yesBulletin of the Chemical Society of Japan, 1991
Abstract The relation between the distribution coefficient of Cs+ on Mn+ form exchanger and the ratio of the solution volume to the exchanger weight (batch factor) at a constant loading of Cs+ has been investigated while taking the activity coefficients of ionic species into consideration when the initial concentration of Cs+ is changed.

Equilibrium and Kinetic Mechanisms of Fluoride Ions Adsorption onto Activated Alumina

open access: yesChemical Engineering Transactions, 2017
In this work, the fluoride adsorption by activated alumina (AAD) was evaluated in batch system. The point of zero charge of adsorbent was obtained. The effects of pH (2 to 12), temperature (30, 40 and 50 °C) and agitation (70, 100, 130 and 160 rpm) in ...
