“…Hence, the amide and amine groups of the proteins and the carboxyl and hydroxyl groups of the carbohydrates are apparently the main functional groups involved in the biosorption of Co 2+ by Lemna gibba. Similar results have been published for the removal of Co 2+ by different materials (Vilvanathan and Shanthakumar, 2015;Anirudhan et al, 2016;Vilvanathan and Shanthakumar, 2016;Pipíska et al, 2017). Various authors have reported the importance of the hydroxyl, amide, carboxyl and amine groups for the removal of diverse metals by the genus Lemna, including Hg 2+ , Cr 3+ , Cr 6+ , Cu 2+ (Rakhshaee et al, 2009), Pb 2+ (Tang et al, 2013), and Au 3+ (Saritha et al, 2014).…”

“…The green garden waste-derived biochar and modified biochar samples were characterized by spectral analysis in the mid-infrared region (4000-400 cm −1 ) to identify major functional groups on biochar samples and changes in the functionality of KNi-HCF-GWB1, KNi-HCF-GWB2, and CA-GWB with respect to modification (Figure 3(a,b)). Slow pyrolysis of green waste biomass at 500°C caused the disappearance of the bands assigned to vibrations of OH groups (3500-3200 cm −1 ) due to the evaporation of water (Pipíška et al, 2017). In addition, aliphatic C-H stretching vibration is not present due to the demethoxylation, demethylation, and dehydration of lignin as was previously reported by Kloss et al (2012).…”

Biochar is a promising metal-immobilizing material, nevertheless the studies of its modification and application in the removal of radionuclides, especially 137 Cs from contaminated liquids remain rare. This research demonstrated that horticultural waste derived biochar (GWB) produced by slow pyrolysis process could be a suitable Cs adsorbent and also useful support to impregnate the potassium nickel(II) hexacyanoferrate(III) (KNi-HCF). Porous materials combining sorption properties of biochar carrier and KNi-HCF have been prepared using simple and efficient impregnation method. The obtained materials (GWB, KNi-HCF-GWB1, and KNi-HCF-GWB2) have been characterized using N 2 adsorption method, SEM-EDX, and FTIR analysis. Compared to GWB, both KNi-HCF biochars showed improved adsorption properties toward Cs + ions, e.g. rapid kinetics, high Cs adsorption capacities (140 ± 3 μmol g −1 for KNi-HCF-GWB1 and 290 ± 9 μmol g −1 for KNi-HCF-GWB2), and high K d values even in the presence of excess of monovalent (Na + + K + + NH 4 + ) and divalent (Ca 2+ + Mg 2+ + Sr 2+ ) cations. High adsorption capacities could be related to synergistic effects of Cs + ion-exchange with KNi[Fe(CN) 6 ] structure and other mechanisms described for unmodified GWB. Rapid adsorption kinetics and high Cs adsorption capacity indicate the suitability of KNi-HCF biochars to treat large volumes of 137 Cs contaminated liquids.

“…A comparison with other forms of carbonaceous sorbents shows that biochar is a promising adsorbent with lower cost for metal removal from water. Much research has recently been conducted to explore biochar efficiency for heavy metal, including Co removal from an aqueous solution [24][25][26][27]. Most of this research has provided sorption mechanisms for metals as a group, however, a comparison of mechanisms for removal of different metals is necessary to describe biochar capacity for heavy metal sorption.…”

Wheat Straw Biochar as a Specific Sorbent of Cobalt in Soil

et al. 2020

There is an urgent need to search for new sorbents of pollutants presently delivered to the environment. Recently biochar has received much attention as a low-cost, highly effective heavy metal adsorbent. Biochar has been identified as an efficient material for cobalt (Co) immobilization from waters; however, little is known about the role of Co immobilization in soil. Hence, in this study, a batch experiment and a long-term incubation experiment with biochar application to multi-contaminated soil with distinct properties (sand, loam) were conducted to provide a brief explanation of the potential mechanisms of Co (II) sorption on wheat straw biochar and to describe additional processes that modify material efficiency for metal sorption in soil. The soil treatments with 5% (v/w) wheat straw biochar proved to be efficient in reducing Co mobility and bioavailability. The mechanism of these processes could be related to direct and indirect effects of biochar incorporation into soil. The FT-IR analysis confirmed that hydroxyl and carboxyl groups present on the biochar surface played a dominant role in Co (II) surface complexation. The combined effect of pH, metal complexation capacity, and the presence of Fe and Mn oxides added to wheat straw biochar resulted in an effective reduction of soluble Co (II), showing high efficiency of this material for cobalt sorption in contaminated soils.
