Chitin Materials: Obtaining; Cleaning of Drains
Summary
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.
