Th r sults show d that th ratio of adsorption r ach d a plat au valu wh n th adsorption tim was 10 min. Th r moval rat s was 95% wh n th ratio of mol cular si v s to wast wat r was 10 g: 1L, and incr as d with d cr asing pH, incr as d with incr asing t mp ratur , but r ach d 93% und r normal t mp ratur . Th saturation adsorbing capaciti s of anilin was 10 mgg, and r gularity of adsorption accord dwith isoth rmal adsorption mod l of Fru ndlich. Sp nt 13X mol cular si v s could b r g n rat d by 20% NaCl und r 60∃ without notic abl loss of capacity. Exp rim ntal r s arch s indicat that 13X mol cular si v s is suitabl for th purification of ph nolb aring wast wat r.
