Abstract:
This study describes the advantages and limitations of trace metal including Pb(II) and Cd(II) ions sorption onto activated hydrochar obtained from waste mango peels. The hydochar prepared by hydrothermal carbonization of biomass under low temperature, which further activated at 400 oC temperature to produce activated hydrchar (ACH). The material characterized physiochemically according to ASTM methods and by other techniques such as BET, XRD, SEM, EDS and FTIR. Equilibrium data for isotherm and kinetic followed Langmuir and Pseudo-second order model for both Pb(II) and Cd(II). The study applied in fixed-bed column experiment for large scale water treatment applications. The obtained results showed that ACH was promising to remove Pb(II) and Cd(II) with obtained column equilibrium adsorption capacities of 38.31 and 3.39 mg g-1 at optimized conditions of bed height, flow rate and metal ions concentration. The obtained experimental results were considered at breakthrough curves and also compared with kinetic models Yoon-Nelson, Adams-Bohart and Thomas according to their linearized forms. ACH compared to commercially available activated carbon was considered promising sorbent and can be suitable for large scale water treatment applications to remove Pb(II) and Cd(II) ions from polluted water
