Determination of hydrogen cyanide concentration in mainstream smoke of tobacco products by polarography
BACKGROUND There has been a worldwide concern for the health risks of cigarette smoking and hydrogen cyanide (HCN) considered as one of the hazardous tobacco compounds which is needed to be determined in order to reduce the dose related to smoke disease risk. In this study, we prepare the experimental procedure to entrap the HCN from mainstream smoke of different brands of Tehran cigarette, thr...
متن کاملPolarography in Molten Salts
TYPES OF MELTS From the practical viewpoint, melts may be classified according to melting points which may limit the available techniques. The lowest melting, with working temperatures up to 250°, are typified by the LiNO3—NaNO3— KNO3 eutectic, NaNO3—KNO3 eutectic, LiClO4, and ammonium formate. With these solvents it is possible to use the dropping mercury electrode, or hanging mercury drop ele...
متن کاملRapid-sweep polarography of cystine.
In their brochure The Principles and Applications of Cathode-Ray Polarography Southern Analytical Ltd. (Camberley, Surrey, U.K.) refer to a paper in which one of their cathode-ray polarographs is used for the determination of amino acids containing thiol and disulphide groups (Coult, 1958). This work apparently takes no account of the fact that the shape of a rapid-sweep polarogram is more depe...

tIt "i,\ 1he:;l:. ; .v This honors thesis is the result of a research project I have worked on since May 1993 and finished in April of 1994 under the direction of Dr. John R. Pichtel, as an undergraduate fellow. The purpose of the research was to develop a new analytical technique for cyanide determination in soils and wastes utilizing ion chromatography. Ion chromatography was evaluated for it...
متن کاملPolarography of diacetylthiamine and dibenzoylthiamine.
In recent years, a series of thiamine derivatives has been synthesized and many investigations have been made both chemically and medically. Allithiamine, a S-alkyl thiamine derivative, was studied in the previous pa per (1) and was found to have polarographically a similar behavior to thia mine. In the present experiment, polarographic investigations on diacetyl thiamine (DAT) and dibenzoylthi...
