This study investigates the adsorption kinetics of Cd(II), Pb(II), and
Cu(II) on hydrochars derived from wheat straw, rice straw, and
bagasse using both conventional and microwave-assisted
hydrothermal treatments. Adsorption experiments were conducted to
evaluate the effectiveness of these materials, with kinetic models
applied to analyze the mechanism. The pseudo-second-order model
demonstrated a better fit for all metals, indicating chemisorption as
the primary process. Modified hydrochars, particularly those
prepared using microwave methods, exhibited significantly higher
adsorption capacities. Among them, m-HRS showed the best
performance, adsorbing 137.36 mg/g of Pb(II). These findings
highlight the potential of microwave-modified hydrochars for
efficient heavy metal removal from aqueous solutions, offering an
environmentally friendly solution to water contamination.
