“…The content of the palm kernel shell is 45% cellulose and 26% hemicellulose [7]. Currently, palm kernel shells have been used as an additive in the manufacture of concrete [8], an additional ingredient in cement production [9], as activated charcoal [10], an additive for road hardeners, an additional fuel for boilers in the palm oil industry, an ingredient in raw charcoal, and sold in the form of shells.…”

One method to reduce the content of heavy metal mercury in wastewater is adsorption. Several media materials have been investigated for use as adsorbents. In this study the characteristics of the palm kernel shell were analysed so that it could be used as an adsorbent. In addition, it also analysed its ability to reduce levels of mercury in wastewater. Palm kernel shells were activated using two types of activators, namely H3PO4 and NaOH and variations in adsorbent sizes of 50 mesh and 100 mesh, as well as variations in contact time for 30 and 60 minutes. Based on the results of this study, it was obtained that the characteristics of the adsorbent of palm kernel shells with the use of H3PO4 and NaOH activators met the quality based on SNI 06-330-95. The adsorption efficiency of mercury (Hg) removal can reach 99.7% with a contact time of 60 minutes and an adsorbent size of 100 mesh activated by NaOH.

“…A Weber-Morris model is an excellent tool in the validation of intra-particle diffusion (Ghannad and Lotfollahi, 2019). The Freundlich isotherm and the extended forms are useful in validating the reaction kinetics of the reaction processes {Yang et al 2019; Fuadi et al 2014;Lotfy et al 2012).…”

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

Beryllium (Be), a lightweight metal with significant industrial applications, poses notable environmental and health risks due to its toxicity and persistence, and widespread use, particularly in the mechanical, aerospace, and electronics sectors. It is commonly alloyed with other heavy metals to enhance material properties. The primary environmental pathways for Be release include emissions from coal and fossil fuels combustion, as well as the incineration of solid wastes. Once introduced into the natural environment, primarily Be associated with soil particles and sediments, particularly in terrestrial and aquatic ecosystems. This review examined the pathways through which Be enters the environment, including atmospheric deposition, industrial discharge, and leaching from natural geologic deposits. The paper highlights the bioavailability and mobility of Be in soil and water systems, emphasizing the geochemical and physical factors influencing its persistence and potential for bioaccumulation. Risk appraisal methodologies are evaluated, with a focus on human exposure routes, including inhalation of airborne particulates and ingestion of contaminated water and food. The toxicological impacts on human health are critically analyzed, detailing both acute and chronic effects, such as respiratory diseases and carcinogenicity. This review evaluates existing regulatory frameworks and remediation strategies, assessing their efficacy in mitigating environmental contamination and exposure to Be. By integrating interdisciplinary research, this paper provides an in‐depth understanding of the environmental behavior and toxicology of beryllium, offering insights that can inform robust policy frameworks and shape future research directions.
