Activated carbon is normally employed for this purpose, however,
due to its high price it has not enjoyed wide-scale application.
Therefore, other inexpensive and effective adsorbents have been
tested for example; biopolymer [8,9] and various low-cost adsorbents
as clays and zeolites material, etc. [10]. Natural zeolite
adsorption is used in the chemical process industries and is playing
important role in cleaning up plant effluent and municipal
wastewater. Especially, clinoptilolite is probably the most abundant
zeolite in nature because of its wide geographic distribution
and large size of deposits. The presence of 4.5 million tons of natural
zeolites of high quality, mainly those of clinoptilolite in Turkey, created
an impetus for the utilization of clinoptilolite in wastewater
treatment.
