TL;DR: In this paper, the efficiency of each biosorbent has been discussed with respect to the operating conditions (e.g., temperature, hydraulic residence time, initial metal concentration, biosorbents particle size and its dosage), chemical modification on sorption capacity and preparation methods, as well as thermodynamics and kinetics.

TL;DR: From the results obtained, the pseudo-second-order kinetic model best describes the biosorption of cadmium, nickel and lead ions.

TL;DR: Desorption studies indicated that metal-loaded biosorbent could be used after three consecutive sorption, desorption and regeneration cycles by applying a semi-simulated real wastewater.

TL;DR: This novel MMBB can effectively be utilized as an adsorbent to remove heavy metal ions from aqueous solutions and calculated thermodynamic parameters indicated feasible, spontaneous and exothermic biosorption process.

TL;DR: The effectiveness of regeneration step by 1 M CaCl2 on five successive cycles of sorption and desorption displays this multi-metal binding biosorbent (MMBB) can effectively be utilized as an adsorbent to remove heavy metal ions from aqueous solutions in five cycles of Sorption/desorption/regeneration.

TL;DR: In this article, low-cost byproducts from agricultural, household and industrial sectors have been recognized as a sustainable solution for wastewater treatment, which allow achieving the removal of pollutants from wastewater and at the same time to contribute to the waste minimization, recovery and reuse.

TL;DR: This review focuses on the utilization of cellulose as an adsorbent in natural/modified form or as a precursor for activated carbon (AC) for adsorbing substances from water and reports a few controversies and unresolved questions concerning the preparation/properties of ACs from cellulose.

TL;DR: This review evaluates the use of adsorbents from four major categories: agricultural waste; naturally-occurring soil and mineral deposits; aquatic and terrestrial biomass; and other locally-available waste materials.

TL;DR: In this article, the effect of various operating factors such as: adsorbent dose, contact time, solution pH, initial concentration and temperature on the sorption of heavy metal ions of Cu(II, Zn(II), Cd( II), Co(II and Pb(II) were carried out using the commercial active carbon Purolite AC 20 and biochar.

TL;DR: In this paper, the efficiency of each biosorbent has been discussed with respect to the operating conditions (e.g., temperature, hydraulic residence time, initial metal concentration, biosorbents particle size and its dosage), chemical modification on sorption capacity and preparation methods, as well as thermodynamics and kinetics.
