This research aims to evaluate the effectiveness of biochars and activated carbons derived from agricultural waste in removing iron and manganese from drinking water.
Conducted batch adsorption experiments with 10 mg/L iron and manganese under regional Queensland conditions.
Tested six types of biochars and six types of activated carbons as adsorbents.
Analyzed adsorption efficiencies and maximum adsorption capacities using isotherm and kinetic models.
Activated carbons achieved 85-99% iron removal and 85-98% manganese removal efficiencies.
Maximum adsorption capacities were 8.01 mg/g for iron and 4.67 mg/g for manganese.
Adsorption kinetics followed pseudo-second order for iron and pseudo-first order for manganese, showcasing different removal mechanisms.
