title: A selective spectrophotometric method for determination of copper with ferron.
abstract: A selective spectrophotometric determination of copper is based on extraction of the copper-ferron complex with tribenzylamine in chloroform at low acidity, and measurement of the absorbance of the yellow extract at 410 nm. Beer's law is found to hold up to 8 microg/ml copper concentration. Of 30 elements tested, only molybdenum interferes. The ratio copper:ferron:tribenzylamine in the extracted species is 1:2:2.
