“…The reported capacities of some adsorbents for U are as follows: 0.05 g/g for composite bentonite,28 ∼0.23 g/g for Fe and Al modified titanium and zirconium phosphates,29 0.23–0.45 g/g for marinealgae,30 0.30–0.39 g/g for interpenetrating polymer networks (IPNs),31 0.307 g/g for cross‐linked persimmon peel gel,32 0.58 g/g for polyurethane foam loaded with crown ether,33 0.76 g/g for benzoylthiourea immobilized on silica gel,34 2.38 g/g for hematite,35 and 29.94 g/g activated charcoal 27. Adsorption capacity of the SPR of 69 g/g is much higher than those of the reported values.…”

Adsorption characteristics of a sulfonated phenol-formaldehyde resin (SPR) have been studied for U removal from aqueous solution by means of batch method. Adsorption experiments have been carried out as a function of contact time, solution/adsorbent ratio, particle size and pH. Adsorption isotherm has been evaluated by changing adsorbent dosage in the range of 0.04-80 g/L at an initial uranyl nitrate concentration of 0.05 mol/L. The enormous adsorption capacity of 0.29 mol/g estimated from the plateau region of the S shaped isotherm is well comparable the Langmuir capacity of 0.31 mol/g. Equilibrium data are also adequately well described by the Freundlich and the Dubinin-Radushkevich (D-R) isotherm equations. The parameters of the isotherms and pH dependency of distribution coefficients (K D ) indicate that polymeric uranyl chains form on bidentate surface complex as a result of solute-solute interactions on the adsorbent surface. Both desorption and elution studies show that uranyl chains are irreversibly bounded on the SPR. Kinetic curves having a fast initial part followed by a slower process well fit both McKay model based on two-resistance diffusion and Nernst-Plank model with single diffusion coefficient.

“…Many ion exchange materials have been developed to extract metal ions from water. This applies primarily to heavy metals and radionuclides [22][23][24][25]. Special attention was paid to hydroxyapatite Ca 10 (PO 4 ) 6 (OH) 2 •xH 2 O-a cheap and highly effective ion-exchanger in neutral media [26,27].…”

The aim of this article was to develop a simple, cheap, light, highly efficient sorption membrane and filtering device for the purification of naturally polluted water with application in outdoor conditions. Sorption membranes have been prepared from cellulose pulp using paper and pulp technology. The sorbents were introduced into paper pulp as a filler (as activated carbon) or were chemically grafted to cellulose fibers. The absorption ability of such membranes assembled in a filter device has been investigated. The removal of weighted small mechanical particles, microorganisms, dissolved organic contaminants and colloids, and the undesirable ion impurities by the filter was investigated. Using a 10 × 10 cm filter, purification and disinfection of 18 liters of natural polluted water from a lake was done. Purification of dirty water occurs with gravity from a tank (bucket).

“…7,8 Among these methods, adsorption is considered to be an effective and economic way forward to extract uranium from seawater. 9 It is reported that various minerals, 10 phosphates, 11 poly-resins, 12 and microorganisms 13 have been used as adsorbents for the recovery of uranium(VI) from wastewater. However, the adsorption capacity of adsorbents to uranium still needs to be improved.…”
