Additionally, an increase in the number of pellets resulted in a rapid increase of uranium concentration in the solution even at 2 M nitric acid concentration and low temperature under irradiation. The values of ln b 1 increase as the mole fraction of methanol in the mixed solvent system increases. The adsorption of cadmium ions from aqueous solutions on rice husk has been exploited. Physicochemical parameters such as selection of appropriate electrolyte, shaking time, concentration of adsorbent and adsorbate were studied to optimize the conditions in which this material can be utilized as adsorbent. The radiotracer technique was used to determine the distribution of cadmium.
Studies show that the adsorption decreases with the increase in the concentrations of all the acids.
The sorption process was found to be endothermic. Its chemical form was presumably a neutral or anionic oxygen containing fluoride. In order to verify that fluoride complexing played a role in the previous study, another series of cation exchange separations was performed with 7-s 265 Sg in which 0.1 M HNO 3 without HF was used as eluent. 265 Sg and 169 W were produced simultaneously by bombarding a 248 Cm target containing Gd with 124 MeV 22 Ne ions. This non-tungsten like behaviour of seaborgium is tentatively attributed to its lower tendency to hydrolyze compared to that of tungsten.
