Model analysis for piperazine (PZ) activated sodium sarcosinate (Na-Sar) for CO2 capture and sequestration for environmental sustainability is challenging and required in-depth analysis. Here, we performed experiments and developed a model for correlating physical properties such as density, refractive index, surface tension, and viscosity of PZ activated Na-Sar for CO2 capture. Physical properties were investigated at different temperatures from 298.15 to 333.15 K and different mass fractions (w1 + w2) of aqueous blends of PZ + Na-Sar were used (0.02 + 0.10, 0.05 + 0.10, 0.10 + 0.10, 0.02 + 0.20, 0.05 + 0.20, 0.10 + 0.20, 0.02 + 0.30, 0.05 + 0.30, and 0.10 + 0.30). All physical properties decreased as temperature increased; however, as PZ in Na-Sar solutions increased, physical properties tended to increase. Refractive index, density, and surface tension showed a linear relationship, while viscosity showed an exponential behavior with the temperature. Empirical correlations were established for all measured properties as a function of temperature and solvent concentration. The correlations showed that the experimentally measured and correlated values were in good agreement. These properties are not available in the literature and are important for the designing of gas–liquid absorption systems. This work can be a useful contribution towards the global efforts to mitigate CO2 from various industrial streams.
