A Rapid and Simple Analytical Method for Cyanogen Chloride and Cyanogen Bromide in Drinking Water
-A simple gas chromatographic method was developed for the determination of cyanogen chloride and cyanogen bromide in drinking waters. Saturated headspace is injected directly onto a capillary column and the analytes are quantified by electron capture detection. Method detection limits are 0.04 and 0.2 #g/l for CNCI and CNBr, respectively. Effects of temperature and salt addition on analyte res...
متن کاملGeneration of cyanogen-free transgenic cassava
Cassava (Manihot esculenta Crantz.) is the major source of calories for subsistence farmers in subSaharan Africa. Cassava, however, contains potentially toxic levels of the cyanogenic glucoside, linamarin. The cyanogen content of cassava foods can be reduced to safe levels by maceration, soaking, rinsing and baking; however, short-cut processing techniques can yield toxic food products. Our obj...
متن کاملCyanogen formation during asymmetric cyanohydrin synthesis.
During asymmetric cyanohydrin synthesis catalysed by vanadium(V)oxo(salen) complexes, the catalysts are reduced to vanadium(IV)oxo(salen) as determined by EPR spectroscopy; the reducing agent is cyanide which is oxidised to cyanogen via a non-radical mechanism.
متن کاملCyanogen Bromide Cleavage and Partial Amino Acid
When samples containing homoserine and homoserine lactone Porcine growth hormone has been cleaved with cyanogen were analyzed, the short column and the first part of the long bromide and the resulting fragments separated by gel filtracolumn (until glutamic acid emerged) were run at 50” instead of tion. The amino acid sequences of the amino-terminal the usua1 55”* Under these conditions homoseri...
متن کاملRapid wetting method to reduce cyanogen content of cassava flour
In 2005 a simple wetting method was developed that reduced total cyanide content of cassava flour 3–6fold. The method involved spreading wet flour in a thin layer and standing in the shade for five hours to allow evolution of HCN gas. We found that breakdown of linamarin catalysed by linamarase to acetone cyanohydrin, followed by its spontaneous decomposition to HCN and acetone was greatly incr...
