The Manufacture and Characterisation of Rosid Angiosperm-Derived Biochars Applied to Water Treatment

Abstract: Marabu (Dichrostachys cinerea) from Cuba and aspen (Populus tremula) from Britain are two rosid angiosperms that grow easily, as a weed and as a phytoremediator, respectively. As part of scientific efforts to valorise these species, their barks and woods were pyrolysed at 350, 450, 550 and 650°C, and the resulting biochars were characterised to determine the potential of the products for particular applications. Percentage carbon composition of the biochars generally increased with pyrolysis temperature, givin… Show more

“…Table 2 shows the percentage yield of biochars produced from screening wood samples A and B, under different pyrolysis temperatures, and operating parameters. The trend in yield is as expected, with increasing pyrolysis temperatures resulting in lower quantities of produced biochars [7]. As the temperature is increased, more volatiles are removed from the system, thereby reducing the biomass within the system, hence the final mass of the biochar.…”

“…Biochars made from renewable sources gave comparable adsorption capacities to commercial activated carbons, even though the surface areas are significantly smaller [5]. As a consequence of these characteristics, biochars produced from different feedstocks, such as walnut wood [6] and rosid angiosperm [7], have been used in water treatment applications. In addition to water treatment, biochars derived from rice husk have been used in acid catalysis [8], while pyrolysed hard wood biochars have found potential application in biodiesel production [9]; biochars as soil enhancement materials can maintain nutrients within soil and control cation exchange, which reduces nutrient leaching from soils [5], while potassium hydroxide-activated biochar offers potential within supercapacitors [10].…”

“…Table 3 shows physicochemical, textural properties and elemental analysis of CLs and CLB. CLB has a relatively high yield when compared with the ones reported by some researchers in the literature for biomass-derived biochar through pyrolysis for wastewater treatment [ 34 , 35 ]. This indicated the feasibility of scaling up the production of this adsorbent for industrial application in treatment of industrial effluents.…”

“…Both tribes consist of species exhibiting similar phylogenetic characters needed to overcome food insecurity and limitations such as inefficient nodulation, and resistance to biotic and abiotic stress constraints. Furthermore, the species within these tribes belong to a super clade called eudicot, which clearly demonstrates diversity in morphology, physiology, ecology and anatomical/structural support mechanisms in response to stresses such as drought and salinity [ 29 ]. Like many of these plants, soybean evolutionarily contains inherent morpho-physiological and biochemical mechanisms that permit it to thrive under high salt stress environments.…”
