From: Carbon dioxide removal from triethanolamine solution using living microalgae-loofah biocomposites
CO2 removal test using the biocomposites system (B) and the suspension system (S) from (a) TEA solution at CO2 loading of 0.8 mol CO2/mol TEA, with varying TEA solution concentrations (0.1, 0.25, 0.5, and 1 M, respectively) and (b) 1 M TEA solution at different CO2 loading levels (0.2, 0.4, 0.6, and 0.8 mol CO2/mol TEA, respectively), over a period of 28 days. Every 4 days, the TEA solutions were measured the amount of CO2 removed and the TEA solutions were refreshed into the bottle with the same concentration and CO2 loading. (Mean \(\:\pm\:\) StDev; n = 3).
