Abstract

The adsorption of Cs(I), Sr(II) and Y(III) from aqueous solutions using silica polystyrene (SPS) impregnated with Aliquat-336 (A-336) and Theonyl triflouroacetone (HTTA) was investigated. The synthesized materials; SPS, A-336@SPS and HTTA@SPS were characterized using FTIR, XRD and SEM. The order of adsorption capacity is Cs(I)>Sr(II)>Y(III). The adsorption capacity (q_e) for Cs(I), Sr(II) and Y(III) was found to be 2.3, 0.75 and 0.55 mg/g, respectively. The maximum separation factor of SF(Cs/Sr), SF(Cs/Y) and SF(Sr/Y) was 16.01, 29.32, and 1.83, respectively. The selective adsorption of Cs(I) by A-336@SPS is attributed to the formation of strong complex between nitrogen atom of A-336@SPS and Cs(I).

浸渍了 Aliquat-336 的硅聚苯乙烯吸附铯（I）、锶（II）和钇（III）的分离可行性

使用浸渍有 Aliquat-336 (A-336) 和三氟丙酮（Theonyl triflouroacetone，HTTA）的硅聚苯乙烯（SPS）研究了水溶液中 Cs(I)、Sr(II) 和 Y(III)的吸附。使用傅立叶变换红外光谱、X 射线衍射和扫描电镜对合成材料 SPS、A-336@SPS 和 HTTA@SPS 进行了表征。吸附容量的顺序为铯(I)>锶(II)>钇(III)。铯（I）、锶（II）和镱（III）的吸附容量（qe）分别为 2.3、0.75 和 0.55 毫克/克。SF(Cs/Sr)、SF(Cs/Y)和 SF(Sr/Y)的最大分离因子分别为 16.01、29.32 和 1.83。A-336@SPS 对铯(I)的选择性吸附是由于 A-336@SPS 的氮原子与铯(I)形成了强络合物。
