[0023] Example 1MnO x - Preparation of starch-bentonite (BS2.5-M25)
[0024] (1) Put 1.25g of cornstarch in a 200mL small beaker, slowly pour 100mL of 5% acetic acid solution to fully dissolve the starch, then add 50g of bentonite to the beaker, and place it in a water bath at 45°C for full stirring and immersion for 10h. Then, the mixture was placed on a small porcelain boat and dried in an oven at 105° C. for 24 hours to obtain a starch-bentonite composite (BS2.5).
[0025] (2) Pour 30 mL of deionized water and 10 mL of absolute ethanol into a 200 mL small beaker, add 8 g of starch-bentonite compound after fully mixing, stir until fully dissolved, add 2 g KMnO Suction filtration was carried out, the product after suction filtration was dried in an oven at 105° C. for 24 hours, and the final sample was recorded as MnOx-starch-bentonite.
[0026] (3) The sample is recorded as BS2.5-M25, where B is bentonite, S is starch, 2.5 represents the percentage of starch quality and be...
