摘要：Based on the strong adsorption, bacteriostatic and bactericidal effects of fulvic acid and silver ions, the preparation of silver alginate deodorizing gel with fulvic acid and its adsorption properties for formaldehyde toxic and harmful gas were studied. In the experiment, silver fulvate was used as the main ingredient, then sodium alginate was used as stabilizer. Under the heating condition, the mixture of fulvic acid silver and sodium alginate was mixed by mass ratio of 0, 0.3:1, 0.5:1, 0.7:1 and 0.9:1, and then immersed in calcium chloride solution to form gel. The new type of silver alginate deodorant gel was prepared and the deodorization of silver fulvate and sodium fulvate silver alginate was prepared. The colloid was characterized. IR analysis showed that fulvic acid was complexed with Ag+. Thermogravimetric analysis showed that the stability of the deodorant gel was greatly improved when the mass ratio of fulvic acid to Ag+ was 1:10.
