| Abstract | The application of novel biomass materials has gained attention for the removal ofhazardous pollutants in the last decades. The waste derived adsorbent was rigorously studiedover the conventional chemical adsorbents. Accordingly, modified guava (Psidium guajava)leaves (MGLP) were used in this study as a biosorbent to remove lead (Pb) and chromium (Cr)from aqueous solutions. The surface properties of modified guava leaves adsorbent were studiedusing techniques including FTIR, pXRD, FESEM, and BET surface area measurements. Batchexperiments were conducted to evaluate dose optimization, adsorbent size, adsorbent behaviour,pH kinetics and isotherms. The adsorption parameters were calculated for MGLP. The Langmuirmodel described the monolayer adsorption mechanism with a maximum adsorption capacity of47.62 mg/g and 54.34 mg/g for Pb (II) and Cr (VI), respectively, with the adsorption kineticsfollowing a pseudo-second order pattern. pH experiments indicate the broad applicability ofMGPL for Pb (II) and Cr (VI) removal across pH range 2-8. These results highlighted MGLPas a cost-effective, biomaterial-based adsorbent for wastewater treatment applications. |
