Web26 okt. 2024 · Strong ions are those ion that dissociate completely at the pH of interest in a particular solution. In blood at pH 7.4: strong cations are: Na +, K +, Ca 2+, Mg 2+ strong anions are: Cl - and SO 42- Strong Ion Difference (SID) is the difference between the concentrations of strong cations and strong anions. Web18 mei 2024 · Herein, on the basis of a conventional gelation strategy of sodium alginate combined with metal ions, Ga 3+ has been innovatively given a dual role in a dual-cross-linked hydrogel. It acts nor only as a cross-linking agent to form a hydrogel material but also as a therapeutic agent to slow-release and continuously treat infected wounds.
