About this document
Cation Analysis in Washing Powder by ecuberoscancotec is a document available to read on EtoBox.
The document describes a method for determining sodium, potassium, calcium, and magnesium in the water soluble fraction of a washing powder using cation chromatography with direct conductivity detection. A 10 mg sample is prepared by dissolving in 100 mL ultrapure water and acidifying to pH 2.5 before analysis. Results indicate the concentrations of these cations in both the water soluble fraction and the washing powder.
