“…Because they have a greater specific surface area and larger micropore volumes, activated C generated at higher temperatures has a higher degree of sorption property (Zhang et al, 2020). According to recent research, bamboo activated C can be utilised to remove heavy metals for environmental reasons (Thotagamuge et al, 2021). In a study, Huang and Wen (2014) used 4-5-year-old thorny bamboo as the raw material for synthesising activated C. The production of bamboo charcoal dropped and the pH value increased as the activation temperature was raised.…”

“…The latter produces less ash than the former because the activator reacts primarily with carbon and not with biomass. As a result of the pores created by the ashes, the activated C produced by two-step activation has a higher degree of adsorption capacity and surface area (Thotagamuge et al, 2021). Furthermore, KOH is the most commonly utilised activator for high-quality activated C production, and it is the most important alkaline salt for activated C production (Chandra et al, 2009).…”

Bamboo is a versatile resource for the synthesis of activated carbon. Low-cost precursors owing to a high growth rate and high carbon content in bamboo have consolidated its suitability as a renewable and notable alternative resource to activated carbon production. The attractiveness of bamboo activated carbon is due to its microcrystalline structure with a high porosity, fast absorption, and highly active surface area. Bamboo activated carbon can be synthesised via carbonisation and activation processes. The carbonisation process produces a substance with a colossal surface area to the mass ratio, which effective in holding various materials, minerals, humidity, odours, etc. Activation process involves the establishment of typical structures and advanced porosity to devise the high porosity of the solid activated carbon. Bamboo activated carbon can be used for energy-related reasons in environmental conservation, agriculture, soil amendment, animal feed additions, and wastewater treatment. It can also be used as a supplement in the composting and fermentation processes, utilised as a tar reduction catalyst in pyrolysis and gasification, as a pelletised fuel, and as a hydrogen production substrate. Numerous studies on activated carbon produced by diverse feedstocks are published in the areas of production, characterisation and possible uses and applications. Bamboo activated carbon is safeguarding its sphere of importance in today's era due to its multipurpose uses. The bamboo activated carbon is mostly used in the industrial, agricultural, and natural environment-related sectors. This paper presents a brief overview of the applications of bamboo activated carbon in numerous areas.

“…Finalmente hay que considerar la importancia de respetar los parámetros del pH de en la producción de sus productos agrícolas Dado que los mismos aportan en gran medida a los procesos de Bio absorción ya que una correcta aplicabilidad afecta la solubilidad de los metales y por lo tanto activa los focos de biomasa por lo tanto en gran medida estos interactúan con los cationes metálicos en los sitios Y cómo la biomasa y el pH interactúan para mejorar los procesos de absorción (Sujata et al, 2021;Thotagamuge et al, 2021;Xia et al, 2021).…”

Los metales pesados son un grave problema a nivel ambiental debido a sus altos niveles de toxicidad para los organismos con los que interactúen una vez son descargados, para enfrentar este problema se han desarrollado diversos métodos de remoción de estos de los efluentes líquidos. En este trabajo se presentan algunos de ellos, destacando sus virtudes y alcances y se comparan con los bioadsobentes que son adsorbentes no-convencionales que se obtienen de partes de plantas y que no necesariamente deben recibir un tratamiento previo para activarse; sin embargo, su activación mejora su capacidad de adsorción. Se abordan los mecanismos que influyen en el proceso de adsorción, de forma de aclarar las mejores condiciones bajo las cuales actúa. Concluyendo que los bioadsorbentes poseen ventajas sobre los adsorbentes sintéticos con una producción de bajo costo, empleando los residuos agroindustriales que no son aprovechados

“…The concentration of arsenic is detected as a function of amount of arsine gas produced [26]. The adsorption capacity of nanocomposite (Qe) and percentage removal efficiency (%R) was calculated by employing Equations (1 and 2) given below [27]: where Qe is the adsorbate amount adsorbed per gram of adsorbent at equilibrium (mg/g), C0 and Ce are the initial and equilibrium concentration of adsorbate (mg/L), V is the volume of solution (L), M is the mass of adsorbent (g) and %R represents the overall removal of adsorbate based on the ratio of adsorbent dosage to adsorbate volume at a particular adsorbate concentration.…”

The groundwater is one of the biggest natural resources for providing drinking water to millions of people all around the globe. However, the presence of large amount of arsenic(V) in water causes serious health hazards to the consumers which necessitates the development of cost-effective remediation. The CuO/TiO2 nanocomposites were prepared by the precipitation-deposition method for the removal of the arsenate ion (AsO43-) from water. The prepared samples were characterized by powder X-ray diffraction, Fourier transform infrared, and scanning electron microscopy to examine crystallite size and structure, material purity, textural features, morphology, and surface area. The effect of different operating parameters such as pH, contact time, initial concentration of arsenic(V) and nanocomposite dose on the removal rate of arsenic(V) was examined to optimize the adsorption performance of the CuO/TiO2 nanocomposite. In addition, the adsorption mechanism was studied by employing Langmuir and Freundlich adsorption isotherms to gain better understanding of the adsorption mechanism. The Freundlich adsorption isotherm fits well with the experimental data and the maximum adsorption capacity of the Langmuir model was found to be 90 mg/g for arsenic(V). The CuO/TiO2 nanocomposite shows remarkable adsorption performance for the treatment of arsenic(V) contaminated water samples. This study provides a cost-effective solution for the safe use of groundwater contaminated with arsenic.
