  In the present study a new method has been developed for the separation and estimation of common metal cations (Li+, Na+, K+), Methyl diethanolamine (MDEA) (and types of alkyl amines) and their degradation products including ammonium ion used in amine processing solution. The acid treating amines such as dimethyl amine (DMA), Diethyl amine (DEA), Dipropylamine (DPA), Diisopropyl amine (DPA) and Dibutyl amine (DBA) in amine processing solution have been separated by Ion Chromatography (IC) using conductivity detector in single column mode. Desired separation was achieved within 20 min using mixture of 3 mM CH3SO3H+CH3CN (90:10) as mobile phase on Dionex Ion Pac SCS1 column at temperature of 30°C. Calibration curve for all the cations (Li+, Na+, K+, NH4+) in the c.. View More»
