Spectrophotometric Determination of Thiocyanate In
Investigative Forensic Sciences © All rights are reserved by Buddha D. Paul and Thomas Research Article Open Access Spectrophotometric Determination of Thiocyanate in Human Saliva by a Unique Iodine-Azide-Chromogenic Substrate Reaction and its Application in Distinguishing Tobacco Smokers from Non-Smokers† Buddha D. Paul and Thomas Bosy Division of Forensic Toxicology, Office of the Armed Forces Medical Examiner, Dover AFB, Delaware, USA. Abstract A method to detect thiocyanate (SCN) in human saliva is presented. Thiocyanate concentrations appear to be diagnostic when classifying smokers or non-smokers, and in determining some clinical conditions. The method involves the reaction of SCN with excess iodine and azide, and spectroscopic detection of unreacted iodine by a chromogenic substrate, ABTS. The calibration was linear over the range of 12.5-150 µmol/L (slope = 0.0086 delta-Abs/SCN µmol/L, intercept = -0.0160 delta-Abs, R2 0.9998). The method was applied to analyze 29 saliva specimens. The results were similar to those obtained from a gas chromatography-mass 2 spectrometry method (slope = 0.9595, R 0.9790). Based on Grubbs equation applied to specimens from non-smoking subjects, a threshold concentration of 1100 µmol/L for SCN was determined to distinguish smokers from the non-smokers. The SCN concentrations in 18 out of 20 saliva specimens collected from 2 smokers were above this threshold. The specimens from smokers were also examined for nicotine and cotinine by a GCMS method. While nicotine concentrations were found to vary, the cotinine concentrations remained stable, 134+29 ng/mL. Generally, the presence of nicotine/cotinine in specimens only indicates exposure to tobacco products, but the presence of any of these compounds with elevated SCN, is an indication of smoking. -

CC BY 4.0 License. 52 Abstract 53 54 Condensed phase uptake and reaction are important atmospheric removal processes for reduced nitrogen 55 species, isocyanic acid (HNCO), methyl isocyanate (CH3NCO) and cyanogen halides (XCN, X =Cl, Br, I), yet many 56 of the fundamental quantities that govern this chemistry have not been measured or are understudied. Solubilities 57 and first-order reaction rates of these species were measured for a variety of solutions using a bubble flow reactor 58 method with total reactive nitrogen (Nr) detection. The aqueous solubility of HNCO was measured as a function of 59 pH, and exhibited the classic behavior of a weak acid, with an intrinsic Henry’s law solubility of 20 (±2) M/atm, and -4 60 a Ka of 2.0 (±0.28) ×10 M (which corresponds to pKa = 3.7 ±0.06) at 298K. -

On the Cyanogen Halides by P
ON THE CYANOGEN HALIDES BY P. KAILASAM (From the Chemistry Department, Madras Christian College) Received July 31, 1941 (Communicated by Sir C. V. Raman, xt., F.R.S., NN.L.) I. Action of Halogens on Cyanogen Halides No observations appear to have been recorded on the action of halogens on cyanogen halides except that of chlorine on cyanogen chloride (Wurtz, 1851; Naumann and Vogt, 1870) and bromine on cyanogen bromide in ether (Poonamarew, 1885) which polymerise them to cyanuric chloride and cyanuric bromide respectively. The object of the present investigation is to study the possible displacement reactions with the cyanogen halides. The action of chlorine gas on cyanogen iodide and the action of bromine on cyanogen chloride were first studied. It was expected that chlorine would displace iodine from cyanogen iodide forming cyanogen chloride, but it was found that cyanogen iodide was not affected by dry chlorine. Dry cyanogen iodide, prepared by warming an intimate mixture of one part of iodine and two parts of AgCN, at about 40°, was sublimed into a narrow tube which could be heated in a water-bath. Dry chlorine was passed through the tube for nearly two hours. No immediate reaction occurred, and even after leaving for a week at room temperature (30°) the white needles of cyanogen iodide remained unchanged. The tube was then slowly heated, but no reaction occurred up to the sublimation temperature of cyanogen iodide (about 40°). It was found that cyanogen iodide could be sublimed unchanged in an atmosphere of dry chlorine. Since chlorine does not displace iodine from cyanogen iodide, it was thought that bromine might displace chlorine from cyanogen chloride form- ing cyanogen bromide. -

The Analysis of Cyanide Silver-Plating Solutions
RP384 THE ANALYSIS OF CYANIDE SILVER-PLATING SOLUTIONS By R. M. Wick ABSTRACT Methods for the analysis of cyanide silver-plating solutions were studied, including the determination of free cyanide, total cyanide, carbonate, chloride, ammonia, silver, iron, copper, and mercury. Electrometric titrations showed that the Liebig method for alkali cyanide is correct to better than 0.2 per cent. Addition of iodide makes the method still more accurate and overcomes the effects of impurities on the titration. The nonagreement of the Liebig and Hannay methods was studied by electro- metric titrations, which showed that the visual Hannay method gives high results although the electrometric Hannay titration is accurate. The determination of total cyanide was accomplished by distillation with sulphuric acid, and of total effective cyanide by titration with iodine. Silver may be separated as silver sulphide, by precipitation with zinc, or by decomposition with acid, after which a determination by any standard method is applicable. Carbonate may be determined by precipitating and filtering out barium car- bonate and titrating it with acid or by titrating a sample with acid after adding silver nitrate to combine with the free cyanide. The usual method for the determination of chloride involves prolonged treat- ment with nitric acid, which converts the precipitated silver cyanide to silver chloride. A new method for separating chloride was investigated in which the silver is precipitated as sulphide and the iron is removed by precipitation as manganous ferrocyanide. The chloride in the filtrate can be determined by the usual methods. Iron and copper can be determined by the regular analytical methods after decomposition of the plating solution with sulphuric acid. -
