文摘

•: Heavy metals removal from petrochemical wastewater (PW) by ion-exchange.
•: Brown marine macro-algae as natural cation exchanger for PW treatment.
•: Trapping of heavy metals by raw biomass occurs by the release of light metals.
•: L. hyperborea showed an useful capacity of 1558, 515 and 528 BV for Cu, Zn and Ni.
•: Desorption using 1.2% HCl eluent (11 BV) was fast and near 100% effective.
