The biosorption process has been established as characteristics of dead biomasses of both cellulosic and microbial origin to bind metal ion pollutants from aqueous suspension. The high effectiveness of this process even at low metal concentration, similarity to ion exchange treatment process, but cheaper and greener alternative to conventional techniques have resulted in a mature biosorption technology. Yet its adoption to large scale industrial wastewaters treatment has still been a distant reality. The purpose of this review is to make in-depth analyses of the various aspects of the biosorption technology, staring from the various biosorbents used till date and the various factors affecting the process. The design of better biosorbents for improving their physico-chemical features as well as enhancing their biosorption characteristics has been discussed. Better economic value of the biosorption technology is related to the repeated reuse of the biosorbent with minimum loss of efficiency. In this context desorption of the metal pollutants as well as regeneration of the biosorbent has been discussed in detail. Various inhibitions including the multi mechanistic role of the biosorption technology has been identified which have played a contributory role to its non-commercialization.

“…On the other hand, different sources from biomass (i.e., wheat bran) have been used to removal of Cu(II), with a removal q m ranging from 17.4 mg·g −1 to 51.5 mg·g −1 , depending whether they are dehydrated or not [ 50 , 51 ]. Fruit peels such as orange ( q m = 50.94 mg·g −1 ; [ 52 ]) and mango ( q m = 46.09 mg·g −1 ; [ 53 ]) and tea tree residues ( q m = 8.64 mg·g −1 ; [ 54 ]), biomass sources from microorganisms have also been used such as: (a) the bacterium Pseudomonas putida ( q m = 89.60 mg·g −1 ; [ 55 ]); (b) Streptomyces coelicolor ( q m = 66.7 mg·g −1 ; [ 56 ]); (c) fungi as Aspergillus niger ( q m = 26 mg·g −1 ; [ 57 ]); (d) algae as Sargassum sp.

In this work, we synthesized chitosan grafted-polyacrylic acid (CS-g-PA) through surface-initiated atom transfer radical polymerization (SI-ATRP). We also studied the adsorption process of copper and lead ions onto the CS-g-PA surface. Adsorption equilibrium studies indicated that pH 4.0 was the best pH for the adsorption process and the maximum adsorption capacity over CS-g-PA for Pb2+ ions was 98 mg·g−1 and for Cu2+ it was 164 mg·g−1, while for chitosan alone (CS), the Pb2+ adsorption capacity was only 14.8 mg·g−1 and for Cu2+ it was 140 mg·g−1. Furthermore, the adsorption studies indicated that Langmuir model describes all the experimental data and besides, pseudo-second-order model was suitable to describe kinetic results for the adsorption process, demonstrating a larger kinetic constant of the process was larger for Pb2+ than Cu2+. Compared to other adsorbents reported, CS-g-PA had comparable or even superior adsorbent capacity and besides, all these results suggest that the new CS-g-PA polymers had potential as an adsorbent for hazardous and toxic metal ions produced by different industries.
