Abstract

As Sumithion or O,O-dimethyl O-(3-methyl-4-nitrophenyl) phosphorothioate has the chemical structure similar to methylparathion or ethylparathion, the analytical methods for the latter compounds can generally be applied to Sumithion with slight modifications. Titration of reduced Sumithion with standardized sodium nitrite (Anonymous 1965 a and b), measurement of 3-methyl-4-nitrophenol formed by alkaline hydrolysis (Anonymous 1964, 1964 a and c; Kovac and Fodrekova 1965, Suzuki 1972), or colorimetric determination of reduced Sumithion according to Averell-Norris (1948) are among the analytical methods analogous to those for methylparathion or ethylparathion. More recently, a gas chromatographic method of analysis has been elaborated which, if applied appropriately, can determine Sumithion content in both technical products and formulated materials more easily and more accurately than some of the foregoing methods. This section deals in detail with several of the representative methods of analysis, stressing the availability and the advantage and disadvantage of each as compared with others.
