“…The infrared spectrum of SDAC and SDACA showed shifts in the characteristic bands of (C=C), (O-H), (NH 2 ), (C=C) and (C-C) to a lower or higher value compared to the spectrum of the uranium-loaded SDAC and SDACA adsorbents. Changes in the peak intensity indicates that U-binding has taken place on the surface of the activated carbon [7,21].…”

“…The Langmuir binding constant (K Lan ) may be used to estimate the practical degree of suitability of the adsorbents. The suitability of the Langmuir isotherm model for describing the sorption of uranium ions onto the SDAC and SDACA surface can be attributed to the homogenous distribution of uranium ions, or chelating sites, on the SDAC and SDACA surface [7]. The separation factor, R L , (Equation (7)) can be used to predict whether a sorption system is favorable or unfavorable.…”

“…Uranium is known to cause acute toxicological effects and harmful diseases for human such as lung, pancreatic, bone and liver cancer [4]. The chemistry of uranium in aqueous solutions is governed by the dioxocation UO 6 ] 6− may also be formed with different concentrations depending on the pH and the total concentration of U(VI) [5][6][7]. Several techniques are used for removal of uranium and trace metals from water, e.g., biotechnology (including agricultural wastes), solvent extraction, coagulation, reduction, ion exchange, reverse osmosis, flocculation, electrochemical and adsorption [8][9][10][11][12][13].…”

“…The adsorption of uranium and heavy metals from the groundwater has been found to be a superior technique compared to other methods because it is a simple, effective, economical, and environmental technique [7]. Activated carbon (AC) is one of the most widely used adsorbents in environmental applications.…”

Abstract:The preparation of highly efficient and low-cost activated carbon from sawdust was achieved for the treatment of uranium-contaminated groundwater. The adsorption properties of the synthesized activated carbon, as well as their ability to be reused, were assessed. The obtained results demonstrated that sawdust activated carbon (SDAC) and its amine form (SDACA) had high affinity towards uranium ions at pH values of 4.5 and 5 for SDAC and SDACA, respectively. The experimental results showed that the maximum adsorption capacity of uranium was 57.34 and 76.7 mg/g for SDAC and SDACA, respectively. A maximum removal efficiency of 89.72% by SDAC and 99.55% by SDACA were obtained at a solid/liquid ratio of 8 mg/mL. The removal mechanism of uranium by SDAC and SDACA was suggested due to interaction with the amine and carboxylic groups. The validation of the method was verified through uranium separation from synthetic as well as from groundwater collected from water wells in the Wadi Naseib area, Southwestern Sinai, Egypt.

“…Numerous techniques have been applied for uranium removal from liquid solution and radioactive solution. Chemical precipitation, ion exchange, liquid membrane, solvent extraction and adsorption are the most commonly used methods [12][13][14][15][16]. Absorption technique has attracted attention in recent decades because of its effective and economic method with high potential for the removal uranium, recovery and recycling of metal ions from liquid solution.…”

Due to extensive variety of nuclear applications, the cost efficient adsorbent is extremely needed for radioactive liquid waste solutions treatment. Bentonite which is consists essentially of clay minerals of the smectite group; have a wide range of industrial uses. In this study, a simple approach to adsorb uranium (VI) from aqueous solution by exchangeable cation by sodium bentonite clay is presented. The effects of contact time, pH of the solution, initial uranium (VI) concentration, adsorbent dosage, and solution temperature on the adsorption of uranium (VI) ions from radioactive liquid solution were investigated. Adsorption isotherms were expressed by Langmuir and Freundlich adsorption models. The theoretical capacity of sodium bentonite clay adsorbent is about 12 mg/g. The optimum adsorption conditions were recommended. About 89% of the loaded Uranium (VI) on modified clay adsorbent was eluted by CH 3 COONa as an efficient eluent. The preferred adsorption and elution conditions were applied on real waste sample and the obtained capacity was determined.

In this paper, a novel composite material the silica grafted by poly(N-vinyl imidazole) (PVI), i.e., PVI/SiO 2 , was prepared using 3-methacryloxypropyl trimethoxysilane (MPS) as intermedia through the ''grafting from'' method. The adsorption behavior of metal ions by PVI/SiO 2 was researched by both static and dynamic methods. Experimental results showed that PVI/SiO 2 possessed very strong adsorption ability for metal ions. For different metal ions, PVI/SiO 2 exhibited different adsorption abilities with the following order of adsorption capacity: Cu 2þ > Cd 2þ > Zn 2þ . The adsorption material PVI/SiO 2 was especially good at adsorbing Cu(II) ion and the saturated adsorption capacity could reach up to 49.2 mg/g. The empirical Freundlich isotherm was found to describe well the equilibrium adsorption data. Higher temperatures facilitated the adsorption process and thus increased the adsorption capacity. The pH and grafting amount of PVI had great influence on the adsorption amount. In addition, PVI/SiO 2 particles had excellent eluting and regenerating property using diluted hydrochloric acid solution as eluent. The adsorption ability trended to steady during 10 cycles.
