3 Claims

1. A method of preparing a ferrous sulfate hydrogel for treating scald infection caused by Pseudomonas aeruginosa, wherein the scald is a deep second-degree scald or a third-degree scald; the method comprising:

S1, obtaining a mixed solution by dissolving ferrous sulfate and vitamin C at a molar concentration ratio of 1:1 in sterile ultrapure water, and heating the mixed solution to 50° C., wherein a molar concentration of the ferrous sulfate in the mixed solution is 2 mM; and

S2, under a condition of heating, continuing to add sodium alginate powder whose mass constitutes 3.5% of a total mass of the mixed solution, stirring until the sodium alginate powder is dissolved and forming a stable colloid, and obtaining the ferrous sulfate hydrogel.
