摘要:
为了研究六价铬在水溶液中的形态及其相互转变规律,用密度泛函理论中的B3LYP方法对H2CrO4、HCrO4-、Cr2O72-、CrO42-进行结构优化,并在相同计算水平下对频率进行计算,其中对Cr采用基组为cc-pVDZ,而其它原子采用6-311+G(d,p)基组。通过静电势分析、原子电荷分析以及热力学分析表明溶液中氢离子与六价铬的结合能力由小到大为H2CrO4
Abstract:
Abstract:To study the speciation and mutual transformation of hexavalent chromium in aqueous solution, the structures of H2CrO4, HCrO4-, Cr2O72- and CrO42- were optimized by B3LYP method of density functional theory, and the frequency was calculated at the same level. The basic group cc-pVDZ was used for Cr, while the other atoms were under 6-311+G(d, p). The analysis of atomic charge, electrostatic potential and thermodynamic energy showed that the binding capacity between hydrogen ions and hexavalent chromium in the solution increased in the order of H2CrO4
