Sodium alginate sustained magnetic vanadate hydr(oxide) hydrogel beads for robust, selective, and record-high uptake of tetracycline from waters

Key Points

• Robust tetracycline uptake shows a maximum capacity of 200 mg per gram of hydrogel beads, providing record-high performance.
• Assessment uses sodium alginate and vanadate to form hydrogel beads that selectively adsorb the antibiotic tetracycline.
• The method ensures efficient contaminant removal through engineered hydrogel materials that optimize adsorption properties.
• Such findings may enable advanced water treatment solutions, highlighting the potential for real-world application.
