Potentiometric determination of nitrilotriacetic acid (NTA) and/or ethylenediaminetetraacetic acid (EDTA) in washing agents

Summary
Application Bulletin No. 76 describes the polarographic determination of small concentrations
(1 ... 100 mg/L) of NTA and EDTA in water. Since in certain countries
legislation has been introduced requiring that phosphates in washing agents should
be replaced NTA and EDTA have become more and more important as complexing
agents and builders.
This bulletin describes the determination of higher concentrations of NTA and/or
EDTA in washing agents by means of potentiometric titration. The ion-selective
copper electrode is used as indicator electrode. Other components normally found
in washing agents do not interfere with this determination.
