Derivatizing Condition of Trace Dicyandiamide with Dansyl Chloride and Application of Spectrum Analysis Method
Asian Journal of Chemistry
A dicyandiamide dansylation procedure compatible with UV spectum was presented. The method provides quickly derivatization while the ratio of dansyl chloride to dicyandiamide over a 10000-fold range, buffer pH of 9.5, ambient temperature of 40 °C and reaction time of 10 min. The method is convenient only using a simple UV spectrometers and successfully achieved method limit of quantification 30 ng/L in water sample.doi:10.14233/ajchem.2014.16752 fatcat:eh35iah4irc6jgk6mery2omwhm
