Abstract
Access to clean, safe water is vital for environmental health and human well-being. We synthesized a magnetic porous superabsorbent via aqueous solution polymerization using acrylic acid, acrylamide, sodium alginate, Fe3O4, and sodium dodecyl sulfate. Its properties were characterized via infrared spectroscopy, scanning electron microscopy, and laser confocal microscopy. The superabsorbent exhibited superparamagnetic behavior with a maximum saturation magnetization of 5.79 emu/g and exceptional swelling, absorbing 258.6 g/g in distilled water. Its continuous porous structure facilitated rapid water absorption. Regarding adsorption, it effectively removed methylene blue, with a capacity of 459.0 mg/g in a 300 mg/L solution. After six adsorption–desorption cycles, it retained 80% of its capacity. These findings suggest a promising strategy for developing high-performance adsorbents to remove organic dyes from aquatic environments.
期刊介绍：
"Polymer Bulletin" is a comprehensive academic journal on polymer science founded in 1988. It was founded under the initiative of the late Mr. Wang Baoren, a famous Chinese chemist and educator. This journal is co-sponsored by the Chinese Chemical Society, the Institute of Chemistry, and the Chinese Academy of Sciences and is supervised by the China Association for Science and Technology. It is a core journal and is publicly distributed at home and abroad.
"Polymer Bulletin" is a monthly magazine with multiple columns, including a project application guide, outlook, review, research papers, highlight reviews, polymer education and teaching, information sharing, interviews, polymer science popularization, etc. The journal is included in the CSCD Chinese Science Citation Database. It serves as the source journal for Chinese scientific and technological paper statistics and the source journal of Peking University's "Overview of Chinese Core Journals."
