Microwave-assisted pyrolysis with chemical activation, an innovative method to convert orange peel into activated carbon with improved properties as dye adsorbent

Abstract

reactivation efficiency of AC. The recovery of AC with improved properties and the desirable process features (fast heating rate, short process time) suggest the great potential of this method as an alternative for the treatment and recovery of fruit peel.

Self‐purging microwave pyrolysis: an innovative approach to convert oil palm shell into carbon‐rich biochar for methylene blue adsorption

“…Biochar can be produced via pyrolysis of a variety of lignocellulose materials such as coconut shell, palm kernel shell, fruit peel, or rice straw . In particular, microwave pyrolysis is becoming a popular pyrolysis approach to produce biochar or activated carbon due to its several distinct advantages . Microwave radiation can provide a rapid and targeted heating effect to the material .…”

“…16 In particular, microwave pyrolysis is becoming a popular pyrolysis approach to produce biochar or activated carbon 17 due to its several distinct advantages. [18][19][20][21] Microwave radiation can provide a rapid and targeted heating effect to the material. 18,20 This can be explained by the occurrence of dipole rotation and ionic conduction at the molecular level of the material.…”

“…[18][19][20][21] Microwave radiation can provide a rapid and targeted heating effect to the material. 18,20 This can be explained by the occurrence of dipole rotation and ionic conduction at the molecular level of the material. 22 The microwave radiation alters the electric field to rotate the molecules of the material and agitate ions, causing collision with the adjacent molecules which subsequently generates internal heating for the pyrolysis reaction to occur.…”

One-step preparation of a novel SrCO3/g-C3N4 nano-composite and its application in selective adsorption of crystal violet

“…[43][44][45] However, certain deciencies including costly, intricate pre-treatment and low adsorption capability limited the use of some certain adsorbents. [46][47][48][49][50][51][52][53] Due to the conjugated region, stacking structure and the weak forces of g-C 3 N 4 , it has the potential for aggregating functional groups or materials to form nanocomposite with multiform favorable properties. [54][55][56] This distinctive structure has drawn great interesting in improving the photocatalytic performance.…”

Utilization of Punica granatum peel as an eco-friendly biosorbent for the removal of methylene blue dye from aqueous solution

“…A literature survey showed that researchers have developed and used a wide variety of low-cost adsorbents for the removal of dyes. Some notable examples are almond shells, 18 Citrus limetta peel, 19 cottonseed hull, 20 Cucumis sativus peel, 21 egg shells, 22 eucalyptus bark, 23 Indian rosewood sawdust, 24 neem leaf powder, 25 mango seed, 26 orange peel, [27][28][29] peanut hull, 30 pomelo peel, 31,32 Psidium guajava leaf, 33 shaddock peel, 34 Terminalia arjuna sawdust, 35 Tectona grandis sawdust, 36 wheat bran, 37…”
