Conversion of marine waste and carbonated water into hydrogels by CO₂ emission behavior
Carbon dioxide creates the acidic environment necessary for calcium ions to bind alginate chains and form a hydrogel. However, the rapid release of CO2 after gelation limits the availability of calcium ions and reduces the cross-linking of alginate chains. Credit: Reprinted from Teshima et al. With permission from the Royal Society of Chemistry Hydrogels are soft materials made of cross-linked…
