Uranium Adsorption from Aqueous Nitric Acid Solution by Solvent Impregnated Polypropylene
- 1. Nuclear Materials Authority, Cairo (Egypt)
Description
The present work studies the adsorption of uranium from nitric acid solution using the extraction chromatography technique (solvents impregnated material), where Di-2 ethyl hexyl phosphoric acid (D2EHPA) organic solvent was impregnated on polypropylene polymer as a suitable adsorbent. The influence of various factors affecting the impregnation process including solvent concentration, temperature, impregnation time, mass/volume ratio and diluents type were optimized. The relevant factors affecting uranium adsorption onto the prepared adsorbent of D2EHPA impregnated polypropylene (SIPP) including initial uranium concentration, contact time, solution ph, mass/volume ratio and temperature were investigated. From the obtained adsorption results different isotherms were fitted. The calculated theoretical capacity of prepared adsorbent was 1.0 g U/g polypropylene impregnated D2EHPA
