In vitro, the comparison of Natural Zeolite and Nano – zeolite to absorb ammonia to rainbow trout (Oncorhynchus mykiss)

One of the best materials for removing of ammonia compounds from water ambient is zeolite Natural resins, such as zeolite, are used in removing ammonia from wastewater culture systems. They are further characterized by ability to loss and gain water reversibly and to exchange some of their constituent elements like Na+ and K+ with ammonium ion without major change of structure (Boranic 2001). The adsorption characteristics of any zeolite are dependent upon the detailed chemical-structural makeup of the adsorbent (Ackley, 2003). Recently, application of Nano- zeolite is important. The Nano- zeolite is a kind of Clinoptilolite that prepared after processing on natural Clinoptilolite. In nature, these charges were satisfied by attraction of cat ions from the surroundings (Keith, 1981). However, the cat ions on Nano -zeolite readily exchange with other cat ions. Recently, it has been used in detergents, aquaculture ponds and nuclear treatment, but it also has large potentials for other applications in liquid waste treatment (James et al. 2000). This research tried to prevent acute toxicity of ammonia compounds on rainbow trout by Nano- zeolite and Natural Zeolite.
