“…Adsorption materials can mainly be divided into organic and inorganic adsorbents. 9 Diatomite, 10 zeolite, 11 kaolinite, 12 and graphene oxide 13,14 are extensively used as inorganic adsorbents because of their high porosity and large surface area. Organic adsorbents can be classified into natural and artificial organic adsorbents.…”
