Acetone System

The photodecomposition of acetone vapor at 255 °C sensitized by Cd 3P1 atoms has been investigated. On irradiation of the Cd–acetone system at 3261 Å, both direct and sensitized reaction occur. CO and CH4 are the only significant volatile products, and their yield is decreased by addition of SF6 as inert quenching gas. The required participation of triplet acetone molecules in the sensitized reaction and the virtual identity of the direct and sensitized decompositions provide additional evidence for the importance of this excited species in direct photolysis.

Abstract Column chromatography was used to separate malathion from other pesticide formulations prior to spectrophotometric measurement. Malathion is separated by a petroleum ether-acetone system on a Florisil column. The chromatographic procedure is applicable to technical preparations, emulsifiable concentrates, dusts, and water-based fruit fly bait.

Colorimetric Procedure

A modification of the dithizone colorimetric procedure for determination of lead has been developed. By working in an aqueous acetone system (70% acetone by volume) the usual extraction step is avoided. Aqueous ethanol or methanol may also be employed or, under suitable circumstances, water may be omitted from the solvent system. The 70% acetone system proposed is tolerant of cyanide, added to convert interfering ions into non-interfering complex ions, and the interference of copper under the conditions adopted was determined. This system was also found compatible with hydroxylamine, used as stabilizer, and with the barbital buffer. A reproducibility of about 2% was obtained when working with standards in the range from 0 to 10 μg. of lead and the technique was found to be sensitive to 0.1 p.p.m.
