Abstract
Biosorption is the method to remove heavy metals from the ecosystem, and it has replaced the use of other physical and chemical methods that are used for removal of heavy metals. The main cause of heavy metal pollution is industrialization. The industrial waste that contains heavy metal leads to pollution in aquatic life systems. It is also poisonous to humans and other animals. The major highlight of this chapter will be the mechanism of various biosorption processes with the help of different biosorbents such as several micro-organisms, non-living biomass, and some herbal plants. It is eco-friendlier as well as cost effective. Nowadays, vegetable waste and fruit peels are also used as biosorbants for the removal of heavy metals.
