| Abstract: | In this study,the ability of macroalgae Gracilaria sp.of removing eutrophication factors and toxic heavy metals Al,Cr,and Zn in a closed cultivation system is reported.The results show that the concentration of the three heavy metals decreased significantly during the experimental period in an algal biomass dependent manner.The biofiltration capacity of the alga for Al,Cr,and Zn is 10.1%-72.6%,52.5%-83.4% and 36.5%-91.7%,respectively.Using more materials resulted in stronger heavy metal removal.Additionally... |
