摘 要: 在含硅酸钠的碱性基本溶液中，研究植酸(C6H18O24P6)浓度对溶液电导率的影响。采用四因素三水平正交实验，研究环保型电解质如氢氧化钠(NaOH)、硅酸钠(Na2SiO3∙9H2O)、硼酸(H3BO3)、钨酸钠(Na2WO4∙2H2O)、铝酸钠(NaAlO2)和碳酸钠(Na2CO3)对溶液电导率的影响规律。结果表明：随着植酸和硼酸浓度增加，溶液电导率减小；随着NaOH、Na2SiO3∙9H2O、Na2WO4∙2H2O、Na2CO3和NaAlO2浓度增加，溶液电导率增大。

Abstract:In an alkaline basic solution containing sodium silicate, the influence of phytic acid (C6H18O24P6) concentration on the solution conductivity was studied. The influence regularities of environmentally friendly electrolytes, such as NaOH, Na2SiO3∙9H2O, H3BO3, Na2WO4∙2H2O, NaAlO2 and Na2CO3, on the solution conductivity were systematically studied by the orthogonal experiment with four factors and three levels. The results show that the solution conductivity decreases with the increase of phytic acid and boric acid, but increases with the increase of Na2SiO3∙9H2O, NaOH, Na2WO4∙2H2O, Na2CO3 and NaAlO2 concentrations.
