Abstract:
This article was aimed to study macroporous resin adsorption kinetics for effective extraction of water ex-tracting with alcohol precipitating in cicada slough. PT, APTT and the coagulation-fibrinolysis dynamic figure were taken as main indexes, which were combined with static and dynamic tests, to select the best macroporous resin to separate and purify the extraction. Adsorption kinetics curve was drawn to fit the adsorption kinetics model. The re-sults showed that NKA-9 macroporous resin was more effective in separating and purifying effective extraction than others. The adsorption dynamic behavior was well described by the pseudo-second-order kinetics equation. It was concluded that the adsorption rate was mainly controlled by the intraparticle diffusion.
