Review On Activated Carbon: Synthesis, Properties And Applications

Abstract

Many researchers have reported that a number of control methods were used in waste water treatment. In this work, there are several types of agricultural wastes and fruits were employed to synthesis activated carbon via chemical activation and physical activation process. The obtained activated carbons indicated higher surface area and larger adsorption capacity. This paper describes experimental findings on uses of activated carbon in wastewater treatment, which produced under different conditions such as contact time, initial pollutant concentration, temperature, pH value, adsorbent dosage, particle size and agitation. The adsorption capacity and equilibrium data of different pollutants (dyes, oil, grease waste water, organic pollutants, pesticides, herbicides, heavy metal ions, lignin and tannin colour) were studied through various isotherms. Thermodynamic parameters such as entropy, free energy and enthalpy were investigated.

Assessment of carbonized himalayan chir pine biomass as an eco-friendly adsorbent for effective removal of industrial dyes

“…The process of adsorption occurs due to the van der waal forces and chemical bonding with electrostatic attractions between the activated carbon and the foreign particles 24 , 25 . Its wide range of applications includes water and air purification, cosmetics, chemicals, and pharmaceutical manufacturing 2 , 10 , 26 . All these processes work on the principle of adsorption.…”

Waste bamboo-derived magnetically separable bamboo-activated carbon: from characterization to effective remediation of fluoride (F−) ions from water

“…22,23 Bamboo has moderately high carbon content (48.64%) and low amounts of nitrogen (0.14%), sulfur (0.11%) and hydrogen (6.75%). 24 Carbon obtained from bamboo is rich in minerals, including magnesium, calcium, potassium, and sodium. 22,24 Using it as a lter increases drinking water quality because its minerals are dissolved in water.…”

“…24 Carbon obtained from bamboo is rich in minerals, including magnesium, calcium, potassium, and sodium. 22,24 Using it as a lter increases drinking water quality because its minerals are dissolved in water. Compared with modern carbon lters, bamboo carbon has the added benet of a built-in team of microbes working on decomposing toxic substances; hence, the water is clear of harmful substances, yeasts, and microbes.…”

“…Besides, bamboo charcoal puries the water by adsorbing harmful dyes and acts as a disinfectant for waterborne germs. 24,26 Recently, magnetic separation has turned out to be the most favourable method for environmental purication because it yields no contamination and is easily detached from the water medium under the applied magnetic eld. [27][28][29] Hence, activated carbon from bamboo with magnetic properties has become a new class of intelligent materials that has attracted interest as absorbents to remove toxic materials from the aquatic media using bar magnets.…”
