| Abstract: | The cation exchange capacity,the exchange degrees of coordinated cations and the exchange amounts of K~ ,Na~ ,Ca~(2 ) in Baimiaozi Clinoptilolite were studied by using hydrothermal cation exchange technology.The results showed that the exchange capacity of ammonium cation was 1.73 mmol/g and the exchange degree of coordinated cations was Ca~(2 )>K~ >Mg~(2 )>Na~ .The exchange amount of K~ was 78.2 mg/g belonging to the super capacity exchange in NH~ _4 modified sample,and the exchange amount of Ca~(2 ) was 32.4 mg/g in Na~ modified sample.Baimiaozi clinoptilolite can be applied in the K~ abstraction from seawater and softening of hard water. |
