Figure 1From: Surface complexation modeling of Cu(II) adsorption on mixtures of hydrous ferric oxide and kaoliniteCu adsorption as a function of pH on HFO. Solid concentration is 2 g/L. Lines indicate fits for (A) Dzombak and Morel [4] 2-site HFO model and (B) Sverjensky and Sahai [38] 1-site HFO model calculated using parameters shown in Tables 1 and 2. Replicate experiments (0.1 M NaNO3 and 10-5 M Cu) are distinguished by separate symbols.Back to article page
