Chitin Materials: Obtaining; Cleaning of Drains
AI summary Read the abstract
This review covers chitin and its derivatives (chitosan and chitosan-melanin complexes) as natural biopolymers with potential for wastewater treatment. Researchers discuss their ability to adsorb heavy metals and suspended solids including microplastics from contaminated water streams. The paper positions chitin-based materials as a sustainable option for removing emerging pollutants from wastewater.
The properties of chitin and its derivatives, chitosan and chitosan-melanin complexes, are considered. Their possible sources are analyzed, as well as the possibilities of their use for wastewater treatment, including removal of heavy metal cations and suspended solids, including microplastic particles.

AI summary Read the abstract
Our tap water and wastewater often contain tiny amounts of drugs, pesticides, and even microplastics that standard treatment plants struggle to remove completely. This review paper rounds up existing research on chitosan—a natural material made from shrimp and crab shells—showing how scientists are turning it into sponge-like filters that can soak up these unwanted pollutants from water. While the technology looks promising, the researchers note it still faces hurdles before it can be scaled up for widespread use in real water treatment facilities.
Adsorption of Organic Pollutants from Wastewater Using Chitosan-Based Adsorbents
AI summary Read the abstract
This review examines how chitosan, a natural material made from shrimp and crab shells, can be used to remove organic pollutants including microplastics from wastewater. Different modified forms of chitosan can effectively absorb a range of contaminants like antibiotics, pesticides, and plastic particles from water. Since chitosan is biodegradable and non-toxic, it offers a sustainable alternative to chemical-based water treatment methods for reducing human exposure to microplastics and other pollutants.
