Correction to Polyethylenimine-Magadiite Layered Silicate Sorbent for CO2 Capture Rômulo B. Vieira and Heloise O. Pastore* Environ. Sci. Technol. 2014, 48, 2472−2480; DOI: 10.1021/es404501e. Page 2477. In Figure 3, Correction of the Y-axis from corrected CO2 calibration.
A
problem in the thermal conductivity detector (TCD) was recently discovered that affected the calibration curves and the final values of captured CO2. The affected parts of the manuscript follow below. Page 2476. In Table 1, Column 2 (capacity/mmol g−1), Column 3 (peak 1/mmol g−1) and Column 5 (peak 2/mmol g−1).
