摘要
Amounts of organic phosphorus-containing material e.g. scale inhibitors in a sample are measured by introducing the sample into a continuously flowing carrier medium, then oxidising the material, contacting with a colorimetric agent and measuring the colour intensity. Preferably the sample is in aqueous solution and carrier is aqueous potassium persulphate or permaganate solution which also acts as oxidation agent. Colour intensity is e.g. measured spectrophotometrically.
