采用间歇平衡实验,研究了氯化钠饱和溶液中UO_2~(2+)在Fe(OH)_3中的吸附比(R_s)与V/m的关系。实验结果表明,当UO_2~(2+)起始浓度较低时,铀在Fe(OH)_3的吸附符合Freundlich方程;铀的吸附浓度随吸附剂质量的增加而减少。
The intermittent equilibrium experiment was carried out to study the relationship between adsorption ratio (R_s) and V / m of UO_2 ~ (2+) in Fe (OH) _3 in saturated sodium chloride solution. The experimental results show that when the initial concentration of UO_2 ~ (2+) is low, the adsorption of uranium on Fe (OH) 3 conforms to the Freundlich equation; the adsorption concentration of uranium decreases with the increase of the mass of adsorbent.
