SSA fitted to surface charge data ??; value with question mark; citation in many more papers [HL85], [LMB95], [DM90], [DJL85], [DL78a], [DL80], [BC90], [J81], [BL82], [BRD01], [WDPWX94], [SW99], [ZB99], [ZB04a], [GS02], [TBM02], [WKM03], [OMJCB05], [HVMK05], [FDZ06],[NF10], [MJ08], [MCJ09]; assuming SSA for sake of comparing U(VI) adsorption densities on ferrihydrite to hematite samples |
