Extensive studies have been conducted on multidisciplinary applications of carbon quantum dots (CQDs) in biomedical and environmental science. In this study, we developed a sustainable synthesis for biomass (Achillea maritima (AM) extract) derived-CQDs, incorporating AI-based characterization. We investigated the antioxidant properties and adsorption performance of AM-CQDs against methylene blue (MB). By integrating environmental factors into the optimization, we achieved control over the synthesis of the AM-CQDs. The AM-CQDs demonstrated notable antioxidant capacity with values as follows: CUPRAC assay: 35.76 ± 0.52, ABTS/HRP assay: 21.95 ± 0.31, DPPH assay: 6.13 ± 0.08, and Folin assay: 40.26 ± 0.57. To further assess their antioxidant performance with a comprehensive evaluation, various kinetic model parameters were calculated using the results from the CUPRAC, ABTS/HRP, DPPH, and Folin assays. The adsorption efficiency of the AM-CQDs was evaluated by measuring their capacity to remove MB. The AM-CQDs exhibited remarkable efficiency with a %uptake 64.82, highlighting their potential as an effective adsorbent for MB removal. Overall, this study highlights AM-CQDs’ synthesis and their multifunctional properties as efficient antioxidants and adsorbents for removing MB. The AM-CQDs demonstrate high efficacy in both applications, positioning them as promising candidates for environmental remediation and biomedical applications.
