Abstract
A potentiometric titration of nitrilotriacetate in wastewater and sewage samples and a procedure of sample treatment to eliminate the interferences are described. T13+ and Cu2+ solutions were the titrants and the potentiometric titrations were monitored with a platinum redox electrode. T13+ :2NTA complex formation was found. The lower detection limit was 0. 1 ppm of NTA. The relative standard deviation in sewage samples was 5% and the recovery varied from 90–110%.Keywords
