A fluorometric method for microgram quantities of ethylenediamine residues in milk

A semiquantitative method for the detection of microcapsule residues resulting from microencapsulated pesticide applications

“…Of all of the techniques reviewed (titrimetry, poloragraphy, gas chromatography, etc.) the spectrofluorometric method of Pasarela and Waldron (1967) proved to be the most satisfactory. In an aqueous solution, adjusted to a pH of 10.0, ethylenediamine reacts with adrenochrome to yield a derivative which fluoresces at 510 nm following an activation at 460 nm.…”

“…These methods, however, do either not yield the desired sensitivity or are not conveniently applicable to our procedure. The method for quantitative determination of ethylenediamine in this work is similar to that described by Pasarela and Waldron (1967).…”

Method for determining ethylenebis(dithiocarbamate) residues on food crops as bis(trifluoroacetamido)ethane

“…Several methods have been described for the determination of diamines in tissues, including colorimetry (Morris, 1971), fluorimetry (Pasarela and Waldron, 1967), and gas-liquid chromatography (Smith, 1970). Of these, gasliquid chromatography appears the most selective and offers the possibility of mass spectral confirmation.…”
