From: Eu(III) and Am(III) adsorption on aluminum (hydr)oxide minerals: surface complexation modeling
Surface complexation models describing Am(III) adsorption to corundum as a function of total americium concentration (AmT), ionic strength (I), sorbent solid concentration (Sol.), and partial pressure of CO2(g) (pc). The CDM_Eu curves represent a CD-MUSIC model developed by employing europium sorption data, the CDM_Am curves represent a CD-MUSIC model developed by employing americium sorption data, the DDL_Eu curves represent a DDL model developed by employing europium sorption data, and the DDL_Am curves represent a DDL model developed by employing americium sorption data. Experimental data were derived from (1) Allard et al. [33] and (2) Moulin et al. [34] and full experimental conditions are summarized in Additional file 1: Table S6. The contributions of each individual surface species are illustrated in Additional file 1: Figures S9 (CDM_Eu), S10 (CDM_Am), S11 (DDL_Eu) and S12 (DDL_Am)
