镀铜溶液中游离氰化物的测定 应用资料在稀释后的样品中加入10%的碘化钾后，用0.1mol/L硝酸银溶液滴定法测定游离氰化物浓度。终点是滴定曲线上的最大拐点。根据硝化银溶液的滴定体积计算出游离氰化物的浓度。KGM KYOTO ELECTRONICSMANUFACTURING CO.，LTD.TIQ-94025enL-K-MKYOTO ELECTRONICSMANUFACTURING CO.，LTD. Application Memo Determination of Free Cyanide in Copper Plating Solution 1.Overview After adding 10% potassium iodide to the diluted sample， free cyanide concentration ismeasured by titration with 0.1mol/L silver nitrate solution. The endpoint is the maximuminflexion on the titration curve. The free cyanide concentration is calculated from the titrationvolume of the silver nitrate solution. 2. Apparatus Main unitAutomatic potentiometric titrator (preamplifier STD) Electrode Silver electrode pH glass electrode 3.
