Abstract

In this work, the tertiary amine, 1DMA2P, was employed to study the concentrations of 1DMA2P, 1DMA2PH⁺, HCO₃^-, CO₃² when it is loaded with different CO₂ loadings as determined using the ¹³C NMR technique at 1 M concentration of 1DMA2P, temperature of 301K, and CO₂ loading in the range of 0-0.83 mol CO₂/mol amine. The ion speciation (1DMA2P, 1DMA2PH⁺, HCO₃^-, CO₃^2-) plots of 1DMA2P-H₂O-CO₂ system were developed in the study.
