Adsorbing material for treating thallium-containing wastewater and preparation method thereof

The invention discloses an adsorption material for treating thallium-containing wastewater and a preparation method of the adsorption material. The adsorption material comprises the following components in parts by weight: 1-2 parts of coal gangue powder, 2-4 parts of NaOH, 1-4 parts of KMnO4 and 1.5-6 parts of MnCl2. The preparation method comprises the following steps: preparation of NaX type zeolite, preparation of nano manganese dioxide and preparation of the adsorption material. The coal gangue is prepared into NaX type zeolite by adopting a NaOH alkali fusion hydrothermal synthesis method, then nano manganese dioxide is loaded on the NaX type zeolite, the adsorption capacity of the zeolite and the adsorption and oxidation characteristics of the nano manganese dioxide are utilized, so that the finally obtained adsorption material can efficiently adsorb thallium in wastewater, and a good water purification effect is achieved; the adsorbent can be used for treating thallium-containing wastewater, and can a
