SYNTHESIS OF NOVEL BIOCHAR FROM WASTE PLANT LITTER BIOMASS FOR THE REMOVAL OF ARSENIC (III AND V) FROM AQUEOUS SOLUTION: A MECHANISM CHARACTERIZATION, KINETICS, AND THERMODYNAMICS
Verma, L. and J. Singh.
Journal of Environmental Management 248:109235(2019)
New biochars synthesized from Tectona (TB 800) and Lagerstroemia speciosa (LB 800) dry waste leaf litter was tested for its efficiency to remove As(III) and As(V) from an aqueous solution. A regeneration study revealed that the biochar could be used up to 4 times with good removal % of As(III and V). A thermodynamics study showed that the process of adsorption was endothermic for As(III) and exothermic As(V). The adsorption capacity for As(III) was 666.7µg/g for TB 800 and 454.54µg/g for LB 800, and adsorption capacity for As(V) was 1250µg/g (TB 800) and 714.28µg/g (LB 800).
