Pseudo second order kinetics best described the
biosorption data while desorption results showed that Cu2+ was stable on DN surface.
Langmuir and Freundlich models were applied and found suitable to describe
biosorption of selected metals by the isolated strains.
Specifically, it conducts bioaccumulation based on the incorporation of metals inside the living biomass or
biosorption, in which metal ions are adsorbed at the cellular surface by different mechanisms reported by Vijayaraghavan and Yun (2008).
"Removal of dyes from a synthetic textile dye effluent by
biosorption on Apple pomace and wheat Straw".
Heavy metals are removed from the waste water through the process of
biosorption and bioremediation using microorganisms and it has been proved as a very cost effective and environmental friendly process (Elekwachi et al., 2014; Joshi et al., 2011).
Biosorption of copper ions using rhizoplane bacterial isolates isolated from Eicchornia crassipes ((Mart.) solms with kinetic studies.
Langmuir's and Freundlichs isotherms were also plotted to observe the maximum
biosorption of heavy metal chromium (VI).
In recent years,
biosorption by biologically originated materials in removing heavy metals has drawn more and more attention, largely due to the unique properties of these biomaterials being environmentally unreactive, low cost, effective at low metal concentration and easily reusable [8-9].

biosorption and bioaccumulation processes for heavy metal removal.
