Determination of Small Amounts of Acrylonitrile in Aqueous Industrial Streams

Abstract

copy before it was run through the chromatographic column and after separation both fractions were identified by their infrared spectra. The sample of diborane obtained by collecting the fraction as it came off the column was spectroscopically pure. This method of purification would prove convenient, especially in preparing standard samples for mass speetrographic fragmentation patterns and infrared calibration runs, where even small amounts of impurities can lead to spurious results. ACKNOWLEDGMENTThe authors would like to thank Richard J. Kokes for several stimulating and helpful discussions on the subject of vapor phase chromatography.

Applied Polarography and Voltammetry of Organic Compounds in Pratical Day-To-Day Analysis Part II

“…For routine polarographic determination of low concentrations of acrylonitrile in resins, we use" 5 a method adopted from the procedure described by Daues and Hamner. 487 The sampled d.c. reduction wave and the d.p.p. wave in 2.3 mA/ tetrabutylammonium hydroxide in rnethanol containing 6% water as supporting electrolyte are well developed with a half-wave potential at -2 .…”

Determination of sub-parts-per-billion levels of acrylonitrile in aqueous solutions

“…We here interface DWSEC with inductively coupled argon plasma (ICAP) detection to fractionate and detect dissolved forms of magnesium and calcium in lake and river waters. ICAP is ideally suited to this application because it provides continuous metal monitoring for aqueous samples (2,13) and accepts sample flow rates appropriate for DWSEC. By coupling DWSEC with ICAP detection, we hoped to define at least the minimum number of components of each metal existing in river and lake waters and determine if metal peaks would coelute with ultraviolet-absorbing dissolved organic matter (UVDOM) peaks.…”

Organic Polarography

“…The technique has been used to follow the formation of arylidene derivatives of homophthalimide (XIX) (84) and the alkaline hydrotysis of nonahtykited phthalimides (427,429,431) and Z-alkylphthalimides (86).…”
