CuCl2和CuSO4的核磁共振系数、粘度系数及其与水分子结构的关系
NMR and Viscosity Coefficients of CuCl2 and CuSO4 and Their Relationship to Water Structure
摘要
Abstract
The viscosity coefficient(B) and nuclear magnetic resonance(NMR)coefficient(B') of CuCl2 and CuSO4 and their effects on the 17O NMR chemical shift(δ)of water were determined at low concentrations.From these B and B' values.individual ion'S B and B' values were further calculated.These toefficients and the relationship between aqueous solution concentrations and δ(17OH2) represented the effect of ions on water structure and the median water cluster size in aqueous solutions.CuCl2 and CuSO4 Were both"structure-makers".The effect of CuSO4 on water structure and median water cluster size was more powerful than that of CuCl2.CI-broke more water clusters than SO2-4.Cu2+,had an obvious effect on shortening the proton spin-lattice relaxation time in water and broadening the line width of the NMR spectrum during the NMR relaxation process.关键词
