Model 2 fits the data slightly better – but was it worth it to add another parameter just to get this small increase in model fit? WebThe extended Langmuir model (EL) showed competitive HM immobilization since there was a decrease in the IMAX of Zn (∼90 ± 28 mg kg–1 from SGB) and Cd (∼0.70 ± 0.21 mg kg–1). Negative values of Pb and Cd immobilization at low rates of SGB indicated an increase in those HM availabilities and preferential immobilization for Zn. mohre ministry of human https://grupo-vg.com
