Novel Sorbent for Uranium Sorption from Crude Phosphoric Acid

Novel sorbent prepared from the dispersion of phosphate ore into a phenolic resin was investigated. Uranium sorption behavior from crude phosphoric acid using this novel sorbent (PhP) was compared to the host phenolic resin (Ph).The experimental data showed that, the sorption capacity was 135 mg g1- and 390 mg g1- for PhP and Ph, respectively. Considering the amount of effective material in both sorbents, the sorbent (PhP) contains 2.5 % of the phenolic sorbent (Ph), the theoretical capacity of the new sorbent (PhP) would be decreased by 40 times of the phenolic one (Ph). Actually its uptake capacity decreased only by about three times, this may be attributed to high dispersion of the phosphate ore.
