本文列举了铝制品洗白碱性废水［１］、海水第二脱盐段①和人工配制ＮａＣｌ水溶液②三种水质，采用伏－安法测定权限电流密度后，用三步作图法，分别求出威尔逊修正式中的系数Ｋ，浓度指数ｍ和流速指数ｎ，建立了威尔逊修正公式的新模式：Ｉ_（ｌｉｍ_＝ＫＣ~ｍＣ~（ａ＋ｂｃ）本模式适用于组份复杂、浓度变化范围大的水溶液体系。用该模式计算的极限电流密度值与实验测定值之间的偏差在±１０％之内，具有很好的实用性。
This paper lists three kinds of water quality of aluminum products washing white alkaline wastewater [1], seawater second desalination section (1) and artificially prepared NaCl aqueous solution (2). After determining the authority current density by volt-ampere method, The coefficients of K, concentration index m and flow velocity index n in Wilson’s modified formula are established, and a new model of Wilson’s correction formula is established: I_ (lim_ = KC ~ mC ~ (a + bc) This mode is suitable for the complex components with large concentration range Aqueous solution system.With the deviation between the limit current density calculated by this mode and the experimentally determined value within ± 10%, it has good practicability.
