Phytoremediation is a promising, cost-effective technique for remediating soil contaminated by heavy metals. When using this approach, however, much contaminated plant material will necessarily be generated that cannot be properly treated after the phytoextraction process. This remains an unsolved problem and thus a major hurdle for the commercial implementation of phytoremediation. This study's main objective was to remove several heavy metals and harmful organics from rape seed meal via hydrochloric with 70% alcohol extraction under different...
