Determination of potassium in water
Potassium analysis with CDR CoffeeLab allows, in a simple and fast way, to quantify the concentration of the analyte in the water used for making coffee.
Potassium ions precipitate with sodium tetraphenylborate. The absorbance determined at 420 nm is proportional to the amount of analyte present in the water sample.
The calibration curve was constructed using standard chloride solutions. The trend of the curve confirmed an excellent linearity of the system over the whole measuring range.
