	The effect of anionic surfactants on the zeta potential of hematite dramatically changes with increase of the chain length from C8 to C16. Sodium octyl sulfate did not shift the IEP of hematite at concentration as high as 10(-3) M while sodium hexadecyl sulfate induced sign reversal of the zeta potential to negative over the entire studied pH range (down to 3) at concentration as low as 10-4 M. Various batches of reagent grade sodium dodecyl sulfate had different effects on the zeta potential of hematite over the pH-range 6-10. The discrepancies are interpreted in terms of impurities present in reagent-grade SDS at various concentrations. (C) 2015 Elsevier B.V. All rights reserved
