“…In this regard, low-cost and locally available agro-biowastes have emerged as promising candidates for heavy metal and metalloid removal on an industrial scale. These biowastes, such as plant fibers, fruit and vegetable peels, and byproducts from food processing industries, possess large multi-chemical functional groups, surface area, cation-exchange capacity, and controllable pore structures [30,88]. Their physical preparation as adsorbents adheres to the principles of green chemistry.…”

“…) q e (mg/g): adsorption capacity at equilibrium q t (mg/g): Wattanakornsiri et al investigated the removal of Pb 2+ and Cd 2+ ions from waste aqueous solutions using naturally modified biosorbents derived from three local fruit peels: dragon fruit peel, rambutan peel, and passion fruit peel [88]. The study found that adsorption followed the pseudo-second-order kinetic model, and the adsorption data fit well with both the Freundlich and Langmuir isotherm models.…”

Heavy metal contamination in wastewater is a significant concern for human health and the environment, prompting increased efforts to develop efficient and sustainable removal methods. Despite significant efforts in the last few decades, further research initiatives remain vital to comprehensively address the long-term performance and practical scalability of various adsorption methods and adsorbents for heavy metal remediation. This article aims to provide an overview of the mechanisms, kinetics, and applications of diverse adsorbents in remediating heavy metal-contaminated effluents. Physical and chemical processes, including ion exchange, complexation, electrostatic attraction, and surface precipitation, play essential roles in heavy metal adsorption. The kinetics of adsorption, influenced by factors such as contact time, temperature, and concentration, directly impact the rate and effectiveness of metal removal. This review presents an exhaustive analysis of the various adsorbents, categorized as activated carbon, biological adsorbents, agricultural waste-based materials, and nanomaterials, which possess distinct advantages and disadvantages that are linked to their surface area, porosity, surface chemistry, and metal ion concentration. To overcome challenges posed by heavy metal contamination, additional research is necessary to optimize adsorbent performance, explore novel materials, and devise cost-effective and sustainable solutions. This comprehensive overview of adsorption mechanisms, kinetics, and diverse adsorbents lays the foundation for further research and innovation in designing optimized adsorption systems and discovering new materials for sustainable heavy metal remediation in wastewater.

“…Selama pemrosesan tersebut, kulit buah ranbutan, yaitu 45,7-64,7% dari berat buah segar, dibuang sebagai produk sampingan (Solís-Fuentes et al, 2010). Oleh karena itu, maka kulit buah rambutan dapat dimanfaatkan (divalorisasi) menjadi produk yang lebih berguna, misalnya sebagai bioadsorben untuk cemaran logam berat seperti Pb(II) (Wattanakornsiri et al, 2022).…”

Tempeh is one of Indonesia traditional foods which made from fermentation processed soybean. There is wastewater from tempeh production that usually wasted to the river without further treatment. One of the parameters for wastewater is chemical oxygen demand (COD). Higher COD correlated to the higher risk to the environment. To decrease the COD level of tempeh wastewater valorization rambutan peels as adsorbent was done. The adsorbent was prepared by drying up and powdering rambutan peels. Boehm titration was used to characterize some functional groups of rambutan peels. Optimization of the contact time and the acidity level (pH) was done under room temperature condition. As results, the rambutan peel contains carbocyclic (0,0492%), alkaline functional group (0,0360%), phenol (0,0004%) and lactone (0,0002%). Besides, the optimal condition for the reaction were at pH 11 for 90 minutes that can reduce COD level from 23.840 mg/L to 10.230 mg/L.

La contaminación por metales pesados es un problema de salud pública y ambiental; la contaminación por plomo (Pb) y cadmio (Cd) causa graves daños a la salud humana y a los ecosistemas, especialmente a los acuáticos. En vista de este problema, el estudio tiene como objetivo buscar en la literatura investigaciones relevantes sobre tecnologías de adsorción para iones Cd (II) y Pb (II), en aguas superficiales y efluentes industriales. La búsqueda de trabajos se realizó en las bases de datos Scopus, Web of Science, CAB, ScienceDirect e Engineering Village, utilizando los términos “Tecnologías de adsorción”, “Cd (II)”, “Pb (II)”, “Adsorción iónica”, “Medios de influencia” y “Adsorción de Cd (II) y Pb (II)”, y analizados con la ayuda del software Rayyan y el Microsoft Excel. El análisis de los estudios mostró una extensa diversidad de materiales con capacidad adsorbente, como nanocompuestos, aplicación de microorganismos y biomasas vegetales. Entre los materiales adsorbentes destacó el uso de bacterias del género Bacillus sp. y la aplicación de quitosano libre o asociado; los nanocompuestos basados en quitosano mostraron una capacidad de adsorción de hasta el 98% para el ion Pb (II). El uso del macrófito Potamogeton malaianus permite obtener altos resultados en la adsorción de cadmio en agua; por medio de la fitorremediación la adsorción se produce rápidamente (2 h) y logra un equilibrio dinámico en menos de 72 h. La adsorción media para iones Cd (II) es del 94%, con una capacidad de adsorción en equilibrio de 6,29-6,97 mg/kg. Entre los medios de influencia, el pH, la temperatura, la dosis de adsorbente, el tiempo de contacto y la concentración de iones son los principales factores que interfieren en la actividad adsorbente.
