| description | The invention relates to a wastewater treatment technology, particular to a preparation method of an alpha-type ferric oxide sodium-based bentonite adsorbent for water treatment. The preparation method comprises: under ultrasonic wave-stirring effect, adsorbing polymerized ferrous sulfate polycation on the sheet layer of bentonite with negatively charged surface through electrostatic interaction to form a stable colloidal suspension, and carrying out hydrothermal hydrolysis on the polymerized ferrous sulfate polycation to obtain the alpha-type ferric oxide sodium-based bentonite (alpha-Fe2O3/bentonite) adsorbent. According to the present invention, the preparation method has characteristics of easily available raw materials, mild condition and convenient operation, and is suitable for industrial production; and the prepared alpha-type ferric oxide sodium-based bentonite adsorbent has advantages of high adsorption capacity, high adsorption efficiency, convenient solid-liquid separation,recycling and good dye a |
