氯化银浊度法测定铜电解液中氯离子

摘要

在丙酮存在的条件下,铜电解液中的氯离子与硝酸银反应,形成氯化银乳浊液,用铜电解液的原液（即实验中铜电解液原液没有加硝酸银的试液）作参比,于分光光度计500nm处测定其吸光度,从而得出铜电解液中氯离子的含量.%In the condition of Acetone existence,Chloride ion in Copper electrolyte reacted with Silver nitrate,forming the Silver Chloride emulsion.And then we used the initial copper electrolyte solution（i.e.,copper electrolyte solution without the addition of silver nitrate solution） as reference to determine its absorbance at 500nm in spectrophotometer.Finally,we got the content of Chloride ion in Copper electrolyte.
