Spectrophotometric method for determination parts per million levels of cyclohexylamine in water

摘要: Abstract UV–vis spectrophotometric method for the analysis of cyclohexylamine (CHA) in aqueous medium range 0.3–20 ppm was developed by coupling CHA with sodium 1,2-naphthaquinone-4-sulphonate (NQS). At 470 nm a calibration slope 0.028 OD ppm−1 observed. Minimum detection limit 0.3 standard deviation 0.1 ppm. Reagent concentration and solution pH are optimised studying its effect on absorbance at nm. The applied to analyse evaluating performance ion exchange resin used condensate purification plant (CPP) power station where, is as all volatile treatment (AVT) reagent inhibit steam generator (SG) corrosion. Structure adduct formed NQS elucidated using NMR (1H 13C) IR spectra, CHN mole ratio variation method.
