摘要: This paper presents the investigation of ammonia-nitrogen and phosphates sorption from simulated reclaimed wastewater by modified clinoptilolite. The results showed that clinoptilolite has a high efficiency removal performance. rate reached to 98.46% 99.80%, respectively. surface became loose some pores appeared, which enlarged specific area; contents Na Fe increased, Ca Mg decreased. possesses rapid slow balance characteristics is more consistent with Langmuir isotherm model. adsorption kinetics follows Elovich dynamics equation, describes in aqueous solution as mainly chemical sorption. Results thermodynamics experiment involving reveal process spontaneous endothermic process, driven entropy effect.
