Recovery of uranium from UCF liquid waste by anion exchange resin CG-400: Breakthrough curves, elution behavior and modeling studies

Towards the implementation of an ion-exchange system for recovery of fluoride commodity chemicals. Kinetic and dynamic studies

“…showing an R2 range of 0.886 -0.999 (Supporting Information, Table S11). As a result, it is probable that the dynamic adsorption is dependent on both resin residual capacity and fluoride/AHF concentration [67].…”

Cation resin fixed-bed column for the recovery of valuable THAM reagent from the wastewater

“…It is one of the most popular technologies for the removal of heavy metal ions from wastewaters. Those metal ions include nickel (Dizge et al, 2009;Juang et al, 2006), uranium (Tavakoli et al, 2013), chromium (Alguacil et al, 2004, Palladium (II) (Hubicki et al, 2008), and tungsten (Di Natale and Lancia, 2007). Chromium (III) in wastewater had been proved to be effectively removed by Amberlite IR-120 cation resin column and the Langmuir isotherm was found to be adequate to describe the equilibrium behavior (Alguacil et al, 2004).…”

“…At the same time, the maximum nickel (II) adsorption capacity of resin was revealed to be 170.94 mg g −1 at 298 K (Dizge et al, 2009). Amberlite CG-400 was proved to be an efficient adsorbent for uranium recovery and 90% recovery was obtained by applying 0.5 M HNO 3 desorption (Tavakoli et al, 2013). In aqueous phase, TMAH resulting tetra-methyl ammonium ion (TMA) is a simple quaternary ammonium compound cation form.…”

Recovery of uranyl from aqueous solutions using amidoximated polyacrylonitrile/exfoliated Na-montmorillonite composite

“…The removal or recovery of uranium from aqueous solutions has been concerned in various literatures, and several methods, including extraction [6], precipitation [7], ion exchange [8] and adsorption [9][10][11] have been developed. Among these methods, adsorption by inorganic clay minerals [9], natural organic matters including organism [12], or artificial synthetic materials [10,13] has been proved to be a promising technology and has been studied extensively, because it is simple to operate, easy to modify and friendly to the environment.…”
