Cat.No. 100317  Hydrochloric acid 37 % for anaylsis
Cat.No. 104944  Potassium chlorate for analysis
Cat.No. 116754  Water for analysis
The fact that complex-compounds will be present means that an appropriate pretreatment is necessary.
Sample preparation:
In a glass beaker place 10 ml of the bath fluid with 10 ml of hydrochloric acid 37 % and 3 g of potassium chlorate, mix well and evaporate, on the heating plate, almost to dryness. Dissolve the residue in water for analysis, transfer to a 1000-ml volumetric flask, fill up to volume with water for analysis and mix well.
Determine with the above mentioned test kits
Copper (total) content in mg/l Cu = analysis value in mg/l Cu x 100
