| Abstract: | Experiment was conducted on adsorption characters and influence factors of attapulgite composite adsorbent.The results showed that the adsorption reaction followed pseudo-second-order-rate equation and fitted with Langmuir isotherm.Adsorption rate changed little with variation of temperature and pH.Adsorption was physical exothermic process.Attapulgite composite filter material had high recycling rate after regeneration. |
