Among the naturally occurring polysaccharides, chitosan is second-most abundant polysaccharide. It obtained from chitin through a process known as deacetylation. biodegradable, biocompatible, and non-toxic, which made it suitable for various environmental applications. In present review, structure, properties, characteristics of were discussed. addition, modified forms (including cross-linked, nanoparticles, functionalized, grafted chitosan) enumerated. The applications these in adsorption organic pollutants (such antibiotics, dyes, pesticides, microplastics, polyaromatic hydrocarbons, parabens, polychlorobiphenyls) are comprehensively reviewed. Furthermore, mechanism adsorption, isotherm (Langmuir Freundlich), kinetic models highlighted. Finally, economic viability assessment impact processing tons shrimp shells into annually

Not having the same grade of popularity as other metals like rare earth elements, gold, copper, etc., strontium is a chemical element with wide uses in daily life, which why it appears EU 2023 list Critical Raw Materials. Among sources (with celestine serving raw material) used to recover element, recycling some Sr-bearing secondary wastes under consideration, and also worth mentioning interest removal from radioactive effluents. To reach these goals, several technological alternatives are being proposed, most widely adsorption or one its isotopes on solid materials. The present work reviews recent advances (for 2024) utilization diverse technologies, including leaching, adsorption, liquid–liquid extraction, recovery/elimination Sr(II) common 90Sr 85Sr radionuclides different liquid wastes. While membrane technologies useful for treating Sr-diluted solutions (in mg/L order), extraction more suitable treatment Sr-concentrated g/L order).
