ResumoMelanoidins are dark brown coloured complex amino‑carbonyl biopolymer comprising the chief component present in the distillery wastewater with high organic load. In this study, melanoidin removal from a simulated wastewater system was examined via Fe-impregnated activated carbon. Initially, three different leaf-waste biomass (Ficus benghalensis, Ficus religiosa and Mangifera indica) were utilized for preparing the activated carbon followed by impregnation of iron. Further, these prepared activated carbons were characterized via SEM equipped with EDX, XRD, FTIR, and BET analyses. A Box-Behnken design of experiments was employed for evaluating the effect of various parameters onto the melanoidin removal. With the adsorbent dose (62.5 mg/L), initial melanoidin concentration (550 mg/L), temperature (40 °C) and contact time (75 min) and Fe-adsorbent ratio (30%), the maximum melanoidin removal (85.6%) was achieved from waste leaf biomass of M. indica, depicting its potential for the melanoidin removal from wastewater.
