The authors regret that some errors were printed in the above article. On page 46, in the section of “3.3.2 CO2 solubility ”, the concentration of LysK in the runs of equilibrium CO2 solubility should be 2.27 M (m1 ¼ 3.186 mol kg1 H2O) instead of 2.50 M. Accordingly, the CO2 loadings, a (mol CO2/mole AAS), in Table 8 and Fig. 12 (page 48), were recalculated and represented. The correct data in Table 8 and Fig. 12 are reprinted below. The authors would like to apologize for any inconvenience caused.
