Preparation and characterization of powdered and granular activated carbon from Palmae biomass for mercury removal

Abstract

Two forms of activated carbon (i.e., granular and powdered forms) used to test mercury removal in solution. These activated carbons were obtained from the shells of a palmae biomass and used in mercury ion removal in aquatic systems. The African palmae shell taken out from a broadly and simply full-fledged palm tree. This biomass serves as a precursor in the formulation of activated carbons not documented. The powdered and granular fractions of activated carbons described for chemical composition, isoelectric point, and surface area. The mechanism of reactions and the kinetics involved were studied using the results of protonation and rate limitations. The parameters used in the batch mode study included pH, contact time, initial concentration of the adsorbate and the dose of the activated carbons. A comparison of performances, contact time demonstrated the highest adsorption efficiency of 93% for the powdered activated carbon and 92% for the granular activated carbon. The dosage recorded the lowest adsorption efficiency of 84% using granular activated carbon. Comparatively, this study brought to the fore that activated carbon derived from the Plamae biomass remains a novel bio-sorbent

Valorization of lignocellulosic biomass into sustainable materials for adsorption and photocatalytic applications in water and air remediation

“…Biomass-based activated carbon materials were also used for the fixation of gaseous Hg 0 (Skodras et al 2007 ; Asasian et al 2012 ; Egirani et al 2021 ). Liu et al reported the valorization of seaweed biomass into activated carbon for the adsorption of Hg 0 in the air (Liu et al 2019a , b ).…”

Wheat Straw-Derived Activated Carbon for Efficient Removal of Methylene blue: Kinetics, Thermodynamics, and Adsorption Mechanism

“…Adsorption is one of the widely used and easily implementable technology known for its efficiency in removing organic pollutants and various metal ions [5]. Although commercial activated carbon is the most commonly used adsorbent due to its high adsorption capacity [6], its usage is limited due to its high cost and difficulty in regeneration, particularly for the treatment of large volumes of polluted effluents [5]. Therefore, recent research has focused on exploring alternative adsorbents that are costeffective, environmentally friendly, and preferably sourced from local waste or natural substances [7].…”

Molecularly Imprinted Polymer-Based Nanoporous Carbon Nanocomposite for Effective Adsorption of Hg(II) Ions from Aqueous Suspensions

“…[12]. Numerous papers have been published on the elimination of Hg(II) via various sources, namely molecularly imprinted polymers (MIPs) [13,14], graphene oxide [15,16], activated carbon [17][18][19][20][21], carbon nanotubes [22], biochar [23,24], magnetic materials [25], metals, and metal oxides [26]. Another water treatment technique that is commonly used for Hg(II) removal is adsorption, and this has become a more important technique due to its efficacy, ease, low cost, and practicality at low concentrations.…”
