حذف آمونياك از هوا با استفاده از زيوليت هاي طبيعي ( كلينو پتيلوليت ) ايران

Removal of Ammonia from Air Using Iranian Natural(Clinoptilolite) Zeolites

Nowadays environmental pollution abatement throuth the use of natural adsorbents are becoming more important, therefore, in this project the adsorption behavior of ammonia on some natural zeolites (clinoptilolite) is studied. In this regard, three clinoptilolite samples of various region in iron (Semnan, Meyaneh and Firouzkooh) were crushed, seived and particle size of 425pm to 4mm were used in the dynamic experiments. The breakthrough curves were plotted, and breakthrough, saturation capacity were calculated in various concentrations, tempratures and flow rates. In general, the obtained preliminary results showed that, the Iranian natural clinoptilolite are suitable adsorbents for ammonia gas. sssln similar conditions, bareakthrough time of Meyaneh sample (135 min) and adsorption capacity of Semnan sample (6.35 mg/g) was higher than others.
