求翻译下面句子,谢谢。
The obtained spectra of aqueous Np(V) solutions confirmed the predominance of the fully hydrated species NpO2+ up to pH 7.7, predicted by the updated NEA thermochemical database. From the Np(V) sorption studies on TiO2, stable surface species of NpO2+ are derived. The type of the sorbed species can be elucidated by a spectral shift (~30 cm-1) to lower wavenumbers of the antisymmetric stretching vibration υ3(NpO2+) compared to the aqueous species suggesting an innersphere complexation. Outer-sphere complexation is found to play a minor role due to the pH independence of the sorption species throughout the pH range 4-7.6 . The comparative spectroscopic experiments of Np(V) sorption onto TiO2, SiO2, and ZnO indicate structurally similar bidentate surface complexes.

得到的Np(V)水溶液光谱证实了NpO2+完全水化到ph达7.7时候的优势,而这此前已由最新NEA热化学数据库预测过。由Np(V)在TiO2上的吸附研究可知,NpO2+在表面稳定产生。吸附的物质类型可由谱位移阐明,反对称伸缩振动υ3(NpO2+)比起水溶液往更低波数的发生位移(约30cm-1),说明内半球络合的形成。由于吸附作用在ph为4-7.6的环境下与ph无关,故外半球络合的影响极微弱。Np(V)分别吸附于TiO2, SiO2, and ZnO的对比光谱实验指出了结构相似的双配位基表面复合物。
