The objective of this research was to synthesize biochar sorbents from waste biomass of Malus floribunda (ornamental apple), Ananas comosus (pineapple), Arachis hypogaea (peanut), Capsicum annuum L. (red pepper), Hordeum vulgare L. (barley), Musa paradisiaca (banana) and Borago officinalis (borage), as well as to evaluate and to compare their sorption capabilities in a batch system. The heavy metal sorption potential of these biochars was evaluated for target pollutants that may be present in the aqueous environment (Pb2+, Cd2+, Cu2+, Mn2+, Ni2+ and Co2+ ions). Several instrumental analytical techniques were employed to examine the composition of biochars, including X-ray diffraction (XRD), scanning electron microscopy (SEM), and Brunauer-Emmett-Teller (BET) analysis and elemental analysis. The results indicate that biochar derived from Borago officinalis exhibited a remarkable removal efficiency (>80%) for Cd2+, Cu2+, Co2+, and Mn2+ ions even with a small amount of sorbent (50 mg). In addition, biochar obtained from both Borago officinalis and Musa paradisiaca demonstrated high efficacy for the sorption of Ni2+ ions. The sorption efficiency of biochars exhibited a positive correlation with an increase in the specific BET surface area and C percentage. Consequently, biochars derived from Borago officinalis and Musa paradisiaca could be effectively used to eliminate certain hazardous heavy metal ions from aqueous solutions.
