Microalgae, with their rapid growth and broad availability, offer significant potential as biosorbents for wastewater dye removal. This study develops a novel biocomposite film combining pectin, alginate, surfactant-modified Chlorella vulgaris biomass to help methyl orange (MO), an anionic azo that is widely used in industry, adsorb the film. Hexadecyltrimethylammonium bromide (HTAB) was prepare biomass, calcium chloride cross-linking embed it biopolymer matrix. Characterization reveals increase surface area pore size due encapsulation, while adsorption driven by electrostatic forces, hydrogen bonding, hydrophobic interactions. Batch experiments examined effects of pH (2–10), concentration (50–300 mg/L), contact time (up 1440 min), temperature (30–50 °C) on adsorption. Optimal conditions included 8.0, 420 min time, 30 °C, achieving maximum MO uptake 112.06 ± 1.18 mg/g. Morphological analysis showed biocomposite's had powdery residue left over after adsorbed. higher levels carbon oxygen, which consistent dye's composition. The exhibited two points zero charge at 4.0 11.9. Adsorption data fit Freundlich isotherm pseudo-second order equation, thermodynamic confirmed exothermic spontaneous nature process. finding highlights this economical efficient removal, presenting sustainable approach treatment.

The article presents the assessment results on effectiveness of polymer hydrogel and cryogel-based adsorbents for treating natural waters from radioactive contaminants. Nine gels were synthesized, their physico-chemical properties studied, processes selective adsorption elements such as 137Cs, 90Sr, other chemical in aqueous solutions investigated using gels. element by hydrogels cryogels was evaluated placing different pure samples synthesized radioactively contaminated solutions. At same time, activity solution measured before gel into it. Then, placed 3 days. Afterward, after it extracted solution. best characteristics selectivity with respect to 137Cs demonstrated AM:AA/3—2.4 × 10−8 mg/g, AM:AA/2—4.1 10−9 AM:AA/5—3.7 mg/g. Cryogel MAA:AM—7.0 AM:AA/2—5.1 AM:AA/5—1.5 mg/g exhibit highest 90Sr. An potential has been K, Fe, Ni, U.
