Chitosan, a low cost polymer, has been used in many studies for adsorption of heavy metal
ions. This review covers the performance of all those adsorbents which were derived from …

Copper is one of the most well-known heavy metals; while it is an essential nutrient for living
organisms, its excessive presence in wastewaters is equally hazardous, causing a variety of …

Water is the most extensively used raw material in the food and beverage industry. This
industrial sector has a negative impact on the environment and economy as a result of rising …

Herein, Typha angustifolia was used as a charcoal source and chemically modified with a
strong oxidizing agent, potassium permanganate (KMnO 4), to obtain modified Typha …

Chitosan-grafted-poly (acrylic acid)(CS-g-PAA) and chitosan-grafted-poly (2-acrylamido-2-
methyl-1-propanesulfonic acid)(CS-gP (AA-co-AMPS)) hydrogels were synthesized and …

Chemical modifications of chitosan were of interest to scientific researchers for its wide
applications. Chitosan has been widely used for synthesis of unique compounds with …

Modified uncrosslinked and crosslinked chitosan derivatives were investigated as green
sorbents for the removal of copper (Cu2+) and lead (Pb2+) cations from simulated solutions …

Environmentally friendly and recycled polydopamine-functionalized electrospun poly (vinyl
alcohol)/chitosan nanofibers (PVA/CS/PDA) were prepared through a low-energy …

In recent years, there has been rising interest in developing green biocomposite for
industrial wastewater treatment. In the current research work, the novel hydrogel composite …

Due to the inhibition from high-concentration proton, acid-resistant adsorbents (especially
hydrogels) for directly recycling heavy metal cations (HMCs) from strongly acidic …
