The indiscriminate release of chromium-saturated effluent into water bodies has raised concerns regarding its effect on human health and environmental ecology. Therefore, this research aimed to remove hexavalent chromium from an aqueous solution utilizing activated carbon developed Rumex abyssinicus. adsorbent was prepared through chemical impregnation with H3PO4 then thermally at 500 for 2 h. optimization the adsorption experiments performed using Box‒Behnken approach response surface methodology. characterization revealed good quality in terms amorphous structure, maximum specific area 1722.9 m2/g porous surface. Furthermore, results showed that a removal efficiency 95.97% attained optimum working pH 3, contact time 60 min, initial concentration 70 mg/L dosage 0.6 mg/100 mL. Langmuir isotherm model found have best fit experimental data. Moreover, kinetics study pseudo-second-order data best, indicating occurrence chemisorption. Overall, suggested abyssinicus could be effective removing solutions.

Due to the increasing fluoride concentrations in water bodies, significant environmental concerns have arisen. This study focuses on aluminum-based materials with a high affinity for fluorine, specifically enhancing metal–organic frameworks (MOFs) amino groups improve their adsorption and defluorination performance. We systematically investigate factors influencing mechanisms governing behavior of amino-functionalized MOF aqueous environments. An SEM, XRD, FT-IR characterization confirms successful preparation NH2-MIL-101 (Al). In 10 mg/L ion solution at pH 7.0, removal efficiency increases dosage (Al), although marginal improvement decreases beyond 0.015 g/L. Under identical conditions, capacity (Al) is seven times greater than that (Fe). demonstrates effective across broad range, superior uptake acidic conditions. At concentration 7 mg/L, g 3.0, equilibrium achieved within 60 min, 31.2 mg/g. analysis using isotherm models reveals follows monolayer model, while kinetic studies indicate predominant mechanism chemical adsorption. research provides scientific basis advanced treatment fluoride-containing wastewater, offering theoretical practical contributions.

Dental caries, a prevalent global health issue, significantly impacts oral and quality of life. Glass ionomer cements (GICs) compomers, valued for their fluoride-releasing properties, are pivotal in caries prevention management. This study explores the enhancement fluoride release from GICs compomers modified with natural additives—clove oil thymol—at varying concentrations (0.5%, 1%, 2%). These additives, known bioactive antimicrobial were incorporated into dental materials, was measured over 30 days. Disc-shaped specimens fabricated, standardized, tested ion at predetermined intervals (Days 1, 7, 14, 30) using an ion-selective electrode. Results revealed that materials exhibited higher compared to unmodified controls. The 2% clove thymol-modified samples demonstrated greatest cumulative release, dose-dependent effect observed across concentrations. Statistical analysis confirmed significant differences (p < 0.05) between control groups, indicating additives enhance properties effectively. findings underscore potential thymol improving therapeutic efficacy implications sustained prevention. By combining delivery benefits this provides pathway developing advanced restorative address disparities, especially high-risk populations. Future research should focus on optimizing these broader clinical application, ensuring enhanced without compromising structural functional integrity.

Idesia polycarpa Maxim. is a woody oil crop with great potential for edible production. While crude rich in pigments, traditional bleaching methods have limited effectiveness improving its color. In this study, metal-organic framework (MOF) material, MIL-88B(Fe), was synthesized and used the of oil. The adsorption selectivity MIL-88B(Fe) process carotenoids chlorophyll were investigated. results demonstrated that exhibited excellent capability, achieving rate 97.67% 65 min. It showed strong effect on particularly carotenoids. content lutein decreased from 118.27 mg/kg to 0.01 after min bleaching. squalene phytosterol contents minimally affected by process, while free fatty acid slightly increased due high reaction temperature adsorbent properties. best described pseudo-first-order kinetic model, indicating spontaneous endothermic chemical process. Moreover, good safety reusability, making it promising novel other oils pigment vegetable industry.
