“…Various biomasses irrespective of their source like pine bark, Spirogyra, rose petals, rubber leaves, walnut shell and sawdust showed promising biosorption capacities with alkaline pre-treatment. [185][186][187][188][189][190]. Calcium oxide pre-treatment provided strong basic sites on the surface of date pit (Phoenix dactylifera) causing higher biosorption for positively charged Cu(II) and Ni(II) from aqueous suspension [191].…”

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.

“…Moreover, many authors assumed that these capabilities could be improved by selective chemical modification [12,13]. Several modifications [14] consist in acid treatment using HCl, alkali treatment using NaOH, Fenton oxidation with H 2 O 2 /Fe 2+ or formaldehyde stabilization. The aim of this study was to enhance the metal adsorption capacities of barks by introduction of covalently bound carboxyl groups.…”

“…Lignin has been identified in the literature as the main adsorption component of pine bark (Argun et al 2009;Dizhbite et al 1999;Li et al 2010). The presence of significant amounts of oxygen-containing groups (phenolic, carboxyl, hydroxyl, methoxyl) in its matrix structure are prerequisites for sorption activity by mechanisms such as physical adsorption and hydrogen bonding as well as coordination and covalent linking (Dizhbite et al 1999).…”

This two-week anaerobic batch study evaluated 2,4,6-trinitrotoluene (TNT) removal efficiency from industrial pink water by (1) adsorption on low-cost adsorbent pine bark, and (2) adsorption coupled with TNT biotransformation by specialised microbial communities. Samples of the supernatant and acetonitrile extracts of pine bark were analysed by HPLC, while the composition of the bacterial community of the experimental batches, inocula and pine bark were profiled by high-throughput sequencing the V6 region of the bacterial 16S rRNA gene. Integrated adsorption and biotransformation proved to be the most efficient method for TNT removal from pink water. The type of applied inoculum had a profound effect on TNT removal efficiencies and microbial community structures, which were dominated by phylotypes belonging to the Enterobacteriaceae family. The analysis of acetonitrile extracts of pine bark supported the hypothesis that the microbial community indigenous to pine bark has the ability to degrade TNT.
