Cu Zn Pb And Screening In Brisbane

Biosorption of heavy metals An overview

Holan and Volesky27 reported the biosorption of Pb and Ni by biomass of marine algae The multi metal Cu Zn Cu Cd or Zn Cd they found that each of the metals inhibited the sorption of others Biosorption of Cr VI from aqueous solution by green algae Spirogyra had also been reported30 The brown seaweed Sargassum sp Chromophyta was used as a biosorbent for Cu ions34
