Rapid population growth and the resultant pollution of freshwater sources are expected to
create water stress conditions on the world in the near future. Adsorption technique is a …

Methylene blue (MB) is a heterocyclic aromatic compound used as a medication or as a
synthetic dye for textiles. Due to its ecotoxicity, researchers have been investigating its …

Due to the negative environmental effect of methylene blue (MB), researchers have been
investigating several aspects of its adsorption. The kinetics/rapidity is an important aspect of …

In this study, the influence of pyrolysis time and temperature on yield, fixed carbon and
physicochemical properties of the biochar produced from Empty Fruit Bunch (EFB) were …

Polyethylene terephthalate (PET) waste was converted into graphene by pyrolysis, and the
synthesized graphene (SG) was modified into activated graphene (AG) by potassium …

The present study focuses on the preparation of activated carbon (AC) from grape leaves as
a low cost, non-toxic, efficient and available adsorbent for the removal of methylene blue …

In this work, the date palm petiole was transformed into activated carbon implying sodium
hydroxide as the activating agent. The carbon obtained was exerted for the adsorption of …

Waste black tea powder was used as a potential adsorbent to remove methylene blue (MB)
from aqueous solution. Several operating factors in adsorption of MB onto waste black tea …

In this paper, hollow gangue microspheres (GM) were introduced into a geopolymer matrix
through a geopolymeric method; our aim was to synthesize a green and low-cost adsorbent …

The activated carbons were prepared from Phoenix dactylifera rachis (PRAC) and Ziziphus
jujuba stones (JSAC) using chemical activation by H 3 PO 4. Then, they applied to eliminate …
