本研究采用闪蒸纳米沉淀法制备了一系列球形聚苯乙烯-丙烯腈(P(St-co-AN))纳米颗粒。 TEM图像说明了通过调节共聚物的进料初始浓度对晶粒尺寸的可控性。所获得的纳米颗粒随后用羟胺进行偕胺肟化。偕胺肟化的 P(St-co-AN) 共聚物纳米粒子在 pH 1.5 时表现出良好的铀吸附能力，为 37.67 mg g−1。
In this study, a series of spherical poly(styrene-co-acrylonitrile) (P(St-co-AN)) nanoparticles were prepared using flash nanoprecipitation method. TEM images illustrated the controllability of grain sizes by adjusting the feeding initial concentration of copolymer. The as obtained nanoparticles were followed with the amidoximation with hydroxylamine. The amidoximated P(St-co-AN) copolymer nanoparticles showed a good uranium adsorption capacity of 37.67 mg g−1at pH 1.5.
