Assay of organophosphorus compounds using flow injection analysis

机译:使用流动注射分析法测定有机磷化合物

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.
