Nitrophenols are used extensively in the chemical, pharmaceutical, and pesticide industries.
Recently, water pollution caused by nitrophenols has gained worldwide attention. Significant …

Natural clay being locally abundant and cheap material in Algeria can be easily activated to
become a promising adsorbent for phenol removal from aqueous solution. The natural clay …

Activated carbon derived from rattan sawdust (ACR) was evaluated for its ability to remove
phenol from an aqueous solution in a batch process. Equilibrium studies were conducted in …

In the present study, spent tea leaves (STL) were used as a new non-conventional and low-
cost adsorbent for the cationic dye (methylene blue) adsorption in a batch process at 30° C …

Three metal–organic frameworks (MOFs), MIL-100 (Fe, Cr) and NH2-MIL-101 (Al), were
prepared, and their adsorption equilibria for phenol and p-nitrophenol (PNP) from water …

The overall biosorption rate of lead (II) onto mansonia wood sawdust has been determined.
Kinetic modeling revealed that pseudo-second-order kinetics described the experimental …

The batch adsorption was carried out to study and investigate pH, initial concentration of MB,
adsorbent dosage and contact time. The best efficiency of MB removal by Canola residues …

Many papers report that accuracy of the Redlich–Peterson (R–P) isotherm equation (three
parameters) is higher than those of Langmuir and Freundlich isotherm equations (two …

The modification of biochar as a low-cost adsorbent is essential to improve its surface
properties and shows great potential in water decontamination. The iron and zinc doped …

Abstract p-Nitrophenol (PNP), a toxic phenolic compound, must be removed from water to
avoid the damage to the aquatic ecology, animals and even human beings. While …
