Abstract

Modifikasi zeolit alam menjadi material penyinipan Kara telah dilakukan dengan cara impregnasi basah. Impregnasi dilakukan dengan merendam zeolit dalam larutan ammonium sulfat pada konsentrasi 13,2% - 39,6% (b/v) dengan selang 6.6%. Kalsinasi zeolit dilakukan pada 250°C selama 4 jam. Karakterisasi zeolit hasil impregnasi dilakukan menggunakan difraktometer sinar X dan spektrofotometer IR. Kapasitas adsorpsi dan laju desorpsi ditentukan dengan cara gravimetri. Disimpulkan bahwa molekul ammonium sulfat terperangkap dalam zeolit dalam bentuk koktaite. Kapasitas adsorpsi zeolit terbesar adalah 2,95 mmol/g, konstanta laju desorpsi terrendah adalah 0,1261 jam" I. Modification of natural zeolites to saving nutrient material by wet impregnation methode has been done. Impregnation was carried out by immersed zolites in ammonium sulfat solution at 13.2 — 39.6% (w/v) concentration with interval 6.6%. Zeolites was calcinated at 250°C for four hours. Characterization of product was done by using X Ray Difraktorneter and IR spectrophotometer, Adsorption capasity and desorpsion rate determinated by gravimetry methode. It was concluded that ammonium sulfat was occluded in zeolites as koktaite. The highest of adsorpsion capasity is 2.95 mmol/g, the lower desorpstion rate constant is 0.1261h-1.
