Solubility and stability of zeolites in aqueous solution: I. Analcime, Na-, and K-clinoptilolite
Solubility stability zeolites I. Analcime K-clinoptilolite
2012/3/31
The solubilities of analcime and clinoptilolite were determined in dilute, weakly alkaline,aqueous solutions below 300 8 C and at vapor-saturated pressures. Analcimes used in this study were from Mont...
