镀镍溶液中硫酸镍浓度检测方案(自动电位滴定)

镀镍溶液中硫酸镍浓度的测定 应用资料向稀释后的样品中加入氨水、1mol/L氯化铵和MX指示剂后，用0.05mol/L EDTA滴定法测定硫酸镍浓度，终点是滴定曲线上的最大弯曲点，硫酸镍浓度是根据EDTA的滴定体积计算的。KGM KYOTO ELECTRONICSMANUFACTURING CO.，LTD.TIQ-96073enL-K-MKYOTO ELECTRONICSMANUFACTURING CO.，LTD. Application Memo Determination of Nickel Sulfate in Nickel Plating Solution 1.Overview After adding ammonia water， 1mol/L ammonium chloride and MX indicator to the dilutedsample， nickel sulfate concentration is measured by titration with the 0.05mol/L EDTA. Theendpoint is the maximum inflexion on the titration curve. The nickel sulfate concentration iscalculated from the titration volume of EDTA. 2. Apparatus Main unit Automatic potentiometric titrator (preamplifier PTA) Electrode Photometric sensor Interference filter (530nm) 3. Reagents Titrant 0.05mol/LEDTA Additive Ammonia water (28%)， 1mol/L ammonium chloride Indicator Murexide (MX) 4.
