N503浸渍树脂自盐酸体系中吸附Ga(Ⅲ)
|
摘要
以N,N-二(1-甲基庚基)乙酰胺(N503)为萃取剂、苯乙烯-二乙烯基苯大孔吸附树脂(HZ818)为载体,制备了N503浸渍树脂(N503 SIRs),并用红外光谱和热重分析对其进行了表征.研究了该浸渍树脂在盐酸体系下对Ga(Ⅲ)的吸附性能.结果表明:浸渍树脂在3 mol·L~(-1)盐酸浓度下对Ga(Ⅲ)的吸附效果最佳,吸附容量为12. 2 mg·g~(-1),298 K下对Ga(Ⅲ)的吸附平衡时间为6 h,对Ga(Ⅲ)的吸附过程符合拟二级动力学模型,等温吸附符合Langmuir模型.在Ga(Ⅲ)、Cu(Ⅱ)或Ga(Ⅲ)、Al(Ⅲ)的二元混合体系和Ga(Ⅲ)、Zn(Ⅱ)、Fe(Ⅱ)三元体系中N503 SIRs能够选择性吸附Ga(Ⅲ).
N503 solvent impregnated resins were prepared with styrene-divinyl benzene macroporous adsorption resin( HZ818) as the carrier and N,N-2( 1-methyl heptyl) acetamide( N503) as the extractant,and they were characterized by infrared spectroscopy and thermogravimetric analysis. Ga( Ⅲ) adsorption performance from hydrochloric acid system was investigated with the SIRs. It was found that the adsoption capability for Ga( Ⅲ) was 12. 2 mg·g-1at the optimal acidity of 3 mol·L-1HCl solution,and Ga( Ⅲ) adsorption equilibrium time was 6 h at 298 K. The adsorption process for Ga( Ⅲ) is in line with the quasi-second-order kinetic model,and the isothermal adsorption comforms to the Langmuir adsorption model. N503 SIRs can adsorb selectively Ga( Ⅲ) from Ga( Ⅲ),Cu( Ⅱ) or Ga( Ⅲ),Al( Ⅲ) binary mixed systems and Ga( Ⅲ),Zn( Ⅱ),Fe( Ⅱ) ternary systems.
