1. A method for using a natural attapulgite comprising:
mixing a natural attapulgite dispersion, an H2O2 solution, a substrate solution and a buffer solution to obtain a mixture, and subjecting the mixture to enzyme catalysis; wherein
the natural attapulgite dispersion consists of the natural attapulgite and water, and the natural attapulgite dispersion has a concentration of the natural attapulgite of 1-5 mg/mL; and
the natural attapulgite is a one-dimensional fibrous hydrated magnesium aluminosilicate clay mineral.
