Waste phenolic resin derived activated carbon by microwave-assisted KOH activation and application to dye wastewater treatment

Abstract: The waste phenolic resin was utilized as the raw material to prepare activated carbon (AC) used KOH as the activating agent via microwave heating. The phenolic resin was carbonized at 500°C and then performed with a KOH/Char ratio of 4 and microwave power of 700 W for a duration of 15 min. The physic-chemical characteristics of the AC were characterized by N2 adsorption instrument, FTIR, SEM and TEM. The BET surface area and pore volume of AC were found to be 4269 m2/g and 2.396 ml/g, respectively. The activat… Show more

“…Polymeric wastes, such as poly(ethylene terephthalate) (PET) [ 13 , 14 , 15 ], polyacrylonitrile (PAN) [ 16 , 17 ], poly(furfuryl alcohol) (PFA) [ 3 ], polystyrene [ 18 ], phenol-formaldehyde resin [ 19 ], styrene divinylbenzene resin [ 20 ], melamine–formaldehyde resin [ 21 ] were used for AC preparation. However, some of these wastes (e.g., PET [ 22 ]) exhibit relatively low carbonization yields, which is a serious drawback of their use for this purpose.…”

“…Physical activation entails the use of activation gases like steam, CO2, or specific compounds. However, this method, despite being environmentally cleaner, is associated with prolonged activation times, lower production yields, and higher costs [10]. Conversely, chemical activation is typically favored due to its simpler process and more effective activation outcomes [9].…”

“…In this study, the activated carbon was synthesized from the paper waste using the microwave-assisted pyrolysis method. This method is one of the alternative activation techniques to make an activated carbon [6]. The heating process using microwave has some advantages in the synthesis of material, as microwave heating enables the direct, rapid, and selective heating of a material with high efficiency [10].…”
