  • Adsorption of Ammonium Ion and Methylene Blue on Zeolite Rocks Studied in Mineralogical Properties

説明

For the purpose of expanding applications of zeolite rocks occurred in Tochigi Prefecture (Oya, Utsnomiyashi, and Takashio, Yaitashi), their mineralogical properties and adsorptive properties for ammonium ion and methylene blue (M.B.) solutions were examined. <BR>Three zeolite rocks containing 59%, 50% and 28% clinoptilolite, were used in this experiment. Samples of Oya and Takashio origin were found to contain a small amount mordenite. Chemical analyses showed that the samples of Tochigi origin had high Fe2O3 contents, and that there was difference between origins in the composition of exchangeable cations, i.e, alkali metals and alkaline earth metals. Cation exchange capacity (CEC) values were 155, 138 and 69 meq/100 g, respectively. Adsorption rates for ammonium ion tended to conform with increment of zeolite contents. The high adsorption amounts of Ammonium ion and methylene blue with samples of Oya origin were thought to be caused by their content of montmorillonite.
