金属离子的键参数及其难溶氢氧化物pKsp的定量关联研究
Study on Quantitative Structure-Property Relationship of the Insoluble Metal Hydroxide pKsp
【摘要】 研究了影响难溶金属氢氧化物溶度积 (pKsp)大小的有关因素 ,基于逐步线性回归建立了一个pKsp与有关参数的定量关联模型 随后 ,根据金属离子在周期表中的区域及其结构差异进行了分组建模 ,相关系数R分别达到或接近优级水平 (0 994和 0 981) 对模型进行分析发现 ,影响氢氧化物pKsp 的最重要因素是离子电荷z和半径r
【Abstract】 Studies were made on influencing factors concerned to the So lu bility Product (p K sp ) for an Insoluble Hydroxide of Metal.A set of pa rameters were used to linearly correlate p K sp with the stepwise multip le regression (SMR),Afterwards,go on modeling of dividing into groups according to metal ion area among periodic table and it’s structure difference further,the coefficient correlation reaches or close to the excellent grade of levels(0.99 4 and 0.981).Analyse about the model that finds,the most important factor of S olubility Product p K sp is ion electric charge z and radius r.
【Key words】 Insoluble Hydroxide of Metal; p K sp; Quant itative Structure-Property Relationship;
