Adsorption of Lead Using Jackfruit Peel Activated Carbon

Abstract

Abstract. Adsorption using activated carbon that decomposed from agricultural waste has been proven to be effective in removing heavy metals in wastewater. This study was carried out to investigate the adsorption of heavy metals wastewater (Lead) using activated carbon that synthesized from the fruit waste which is jackfruit peel. The efficiency of jackfruit peel activated carbon in removing lead from wastewater has been compared to the commercial activated carbon. Result shows that the commercial activated carbon gave better result as compared to jackfruit peel activated carbon (98% of lead removal for commercial activated carbon and 80% of lead removal for jackfruit peel activated carbon). This can be explained from the characteristics of the activated carbon where the commercial activated carbon has a very well develop pores structures in contrast to jackfruit peel activated carbon. In term of isotherm and kinetic study, the Freundlich isotherm model is better fitted in equilibrium adsorption isotherm for jackfruit peel activated carbon and it is favorable adsorption condition. For commercial activated carbon, the Langmuir isotherm is better fitted to the adsorption of lead and monolayer adsorption capacity was found. The experimental data fitted very well the pseudo second order in kinetic model for both activated carbon where the adsorption controlled by chemisorptions.

Comparative lead adsorptions in synthetic wastewater by synthesized zeolite A of recycled industrial wastes from sugar factory and power plant

“…Two main steps of silicon (Si) and aluminum (Al) extractions by alkaline fusion method and zeolite synthesis by hydrothermal method are commonly recommended for zeolite synthesis [ 16 – 22 ]. However, a raw material is a key factor affecting to the quality of synthesized zeolite because of the different chemical compositions in a raw material.…”

Kinetic studies of the removal of methylene blue from aqueous solution by biochar derived from jackfruit peel

“…Consequently, jackfruit peel presents a promising low-cost and eco-friendly alternative to chemical materials for decontaminating dye wastewater. Some previous studies applied jackfruit peel modi ed by acid or sodium for the removal of metal ions such as Pb(II) (Rosli et al 2015) and Cr(III) and Ni(II) (Ranasinghe, Navaratne &Priyantha 2018), as well as methylene blue (Hameed 2009). However, these studies mainly focused on PFO and PSO in linear forms to estimate adsorption kinetics.…”

Mesoporous carbon materials derived from artocarpus heterophyllus for water desalination and defluoridation using capacitive deionization

“…The outer peels of the ripe fruit are categorized as lignocellulosic biomass with cellulose (54%), hemicellulose (23%) and lignin (3%) content suitable for qualifying it as carbon precursor (Selvaraju & Bakar, 2017). These properties together with its high carbon (>45%) and low extractives (15.3 wt%) content have driven researchers to synthesize porous carbon from this low-cost agricultural waste for various applications including removal of heavy metal such as cadmium (Inbaraj & Sulochana, 2004) and lead (Rosli et al, 2015), adsorption of dyes rhodamine-B (Inbaraj & Sulochana, 2006), methylene blue (Foo & Hameed, 2012) and iodine (Selvaraju & Bakar, 2017) from aqueous solution. To the best of our knowledge, jackfruit peels activated carbon (JFAC) has not been studied as electrode material for CDI.…”
