Abstract

The capacity of the naturally occurring zeolite clinoptilolite has been determined for the ions NH₄⁺, K⁺, Ca²⁺ and Mg²⁺ in the range of total concentrations 0·01 n-0·05 n. The results show that the effective capacity of the zeolite varies according to the ionic species involved in the exchange. Maximum ion uptake was achieved for the exchanges Na⁺ NH₄⁺ and Na⁺ K⁺ and the measured capacities for NH₄⁺ and K⁺ were significantly greater than those measured for Ca²⁺ and Mg²⁺. The data provide a useful pointer to the use of clinoptilolite as a water treatment medium in recirculating aquaculture systems. © 1987.
