Embodiment Construction
[0035] The technical solution of the present invention will be described in detail below according to the drawings and specific embodiments.
[0036] Ag of the present invention 2 The preparation method of S-MMT nanocomposite adsorbent is:
[0037] The first step: preparation of montmorillonite (MMT) dispersion
[0038] Weigh bentonite and place it in a container, add deionized water therein, and stir for 9 hours on a magnetic stirrer to fully swell and disperse bentonite to obtain a dispersion whose main component is montmorillonite. The prepared montmorillonite dispersion molar The concentration is 15g / L;
[0039] Step 2: Preparation of loaded Ag + MMT dispersion
[0040] Add AgNO to the montmorillonite dispersion prepared in the first step 3 Solution, continue to stir on the magnetic stirrer for 3h, so that Ag + Adsorbed on the surface of MMT, the molar number of silver nitrate loaded in the prepared dispersion per gram of bentonite is 0.001mol / g;
[0041]The third s...
