The biomass of the brown seaweed, Ecklonia,was used to remove Cr(VI) from wastewater. Previously,Cr(VI) was removed through its reduction to Cr(III) whenbrought into contact with the biomass. In this study, theeffects of ionic strength, background electrolytes, and Cr(III),Ni(II), Zn(II), and Fe(III) on the Cr(VI) reduction wereexamined. An increased ionic strength inhibited the Cr(VI)reduction. The presence of other heavy metals, such asCr(III), Ni(II), or Zn(II), only slightly affected the Cr(VI)reduction, while Fe(III) enhanced the reduction. Although theabove various parameters could affect the reduction rate ofCr(VI) by Ecklonia biomass, these effects were relativelysmaller than those of pH and temperature. In addition, thepreviously derived rate equation was found to be applicableover a range of ionic strengths and with different backgroundelectrolytes. In conclusion, Ecklonia biomass may be a goodcandidate as a biosorbent for the removal of Cr(VI) fromwastewaters containing various other impurities, and scaleupto a practical process may be accomplished using thepreviously derived rate equation.
