| titleOfInvention | Attapulgite-loaded zirconia adsorbent and its preparation and detection method |
| abstract | The invention relates to an adsorbent for attapulgite-loaded zirconia and a preparation and detection method thereof. The preparation method is as follows: sieving powdery attapulgite, adding deionized water and mixing, and then adding zirconium oxychloride for mixing to obtain a suspension ; Stir and adjust the pH to neutral with ammonia water; then homogeneously disperse the suspension; let it stand until the layers are separated, pour off the supernatant, and rinse the precipitate continuously with deionized water until the chloride ions and ammonium ions are washed away Centrifuge the precipitate with a centrifuge, pour off the supernatant, put it in an oven for drying, and then grind and sieve to obtain a zirconia-modified attapulgite. The detection method is to quickly and accurately quantify the improvement effect of the adsorption rate before and after material modification through simple constant temperature oscillation, filtration, atomic fluorescence detection and other operations. The invention has high adsorption efficiency and fast adsorption speed for the dissolved As(V) and As(III), and greatly reduces the requirement on the reaction system for treating arsenic pollution in water bodies. |
