fa بررسی کاربرد زئولیت کلینوپتی لولایت منطقه سمنان در حذف ازت آمونیاکی از آبهای آلوده سایر تخصص هاي باليني Other Clinical Specialties پژوهشي Original <p>وجود ندارد</p> <div> <p style="text-align: justify;">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Nitrogen compounds are one of the several materials in the<br> &nbsp;&nbsp; wastewaters and effluents that have harmful effects in water resources. In<br> &nbsp;&nbsp; different&nbsp; experiences&nbsp; , Ion&nbsp; Exchange (IE)&nbsp; with&nbsp; Zeolites&nbsp; were&nbsp;&nbsp; used&nbsp; for<br> &nbsp;&nbsp; removal of Ammonia-nitrogen. The aim of this research was studying the&nbsp;<br> &nbsp;&nbsp; application of Semnan&rsquo;s Zeolite for removal of Ammonium in both Batch&nbsp;<br> &nbsp;&nbsp; and&nbsp; Continous&nbsp; systems .&nbsp;</p> <p style="text-align: justify;">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; The Zeolite&nbsp; Clinoptilolite&nbsp; was&nbsp; supplied&nbsp; by&nbsp; Semnan&nbsp; area&nbsp; mines . The&nbsp;<br> &nbsp;&nbsp; Zeolite&nbsp; was&nbsp; ground&nbsp; and&nbsp; sieves&nbsp; based&nbsp; on&nbsp; U.S. standard&nbsp; mesh&nbsp; number&nbsp;<br> &nbsp;&nbsp; 20 , 30 , 40&nbsp; and&nbsp; then conditioned by Ammonium Sulfate&nbsp; and&nbsp; Sodium&nbsp;<br> &nbsp;&nbsp; Chloride&nbsp; solutions&nbsp; respectively .</p> <p style="text-align: justify;">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; The test results on conditioned&nbsp; samples&nbsp; in&nbsp; Batch&nbsp; system&nbsp;&nbsp; was showed<br> &nbsp;&nbsp; that average Ion&nbsp; Exchange&nbsp;&nbsp; capacity&nbsp; for&nbsp; particles&nbsp; with&nbsp; 20&nbsp; ,&nbsp; 30&nbsp; and 40<br> &nbsp;&nbsp; mesh were between&nbsp; 6.65 - 16 mg NH₄⁺ / g&nbsp; Zeolite&nbsp; weight .&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</p> <p style="text-align: justify;">&nbsp;&nbsp; Forthermore&nbsp; its&nbsp; selectivity for other&nbsp; cations obtained the ranking of K , NH₄ ,<br> &nbsp;&nbsp; Na , Ca , Mg&nbsp; respectivly .
