The effect of external and internal diffusion on the sorption of radioactive ions by reactive cloth filter: Part I

Effect of fluid velocity on radioactive ion retention by fluidized‐bed reactor

“…[8,9,11] Ion binding capacity has been measured with the batch equilibration technique while varying the solution pH (pH 6-10) and the concentration of the uranium ions. The required treatment is applied while trying to keep the concentration of the other solution ingredients constant.…”

“…[11] The first two adsorption equations are proportional to e ÀKDt , where K D might be either an external or internal diffusion parameter with a dimension of s À1 depending on equation. [11] The first two adsorption equations are proportional to e ÀKDt , where K D might be either an external or internal diffusion parameter with a dimension of s À1 depending on equation.…”

“…A pseudo-first order chemical reaction rate equation has also been proposed as follows: [11] @q @t A pseudo-first order chemical reaction rate equation has also been proposed as follows: [11] @q @t…”

“…By assuming pseudo-steady state the above three equations are equal, so the following equation can be obtained: [11] @q @t The constant q e (mol/kg) is the equilibrium concentration of the product, i.e., the concentration of metal ion at the end of the moving bed reactor.…”

“…[2,3,8,9] Previous studies were carried out on the synthesis of a reactive chelating polypropylene pellets (RCPP) or sheets for uranium recovery from radioactive waste or sea water. [10][11][12] In the current study, our previous work is continued by studying the effect of fluid velocity on the retention of uranium ions in a three phase fluidizedbed column from liquid active effluents of a fuel manufacturing plant.
