Abstract: Heavy metals and permanent organic pollutants (POPs) are quite stable and harmful, which can endanger human’s life and health directly or indirectly. Nowadays, biosorbents become the hotspot and keystone of the researches on treating heavy metals and POPs. Based on the recent years’ research achievements, this paper made a systematic classification of biosorbents, and expatiated on the mechanisms of heavy metals and POPs adsorption on the outside, surface, and inner cells of the biosorbents, as well as the related affecting factors. Meanwhile, the problems in present researches and future research directions of biosorbents were discussed.
