a Total C sorbed (normalized by specific surface area) onto hydrous Mn oxide (HMO) and goethite as a function of initial C to metal molar ratio in the batch system. The C:Mn molar ratio reflects the initial moles of C in DOC and moles of Mn in the HMO present. The C:Fe molar ratio reflects the initial moles of C in DOC and moles of Fe in the goethite present. b The total C retained on HMO and goethite after extraction with 0.1 M NaH2PO4 as a function of initial C:(Mn or Fe) molar ratio. Error bars indicate standard deviations of triplicates
