STUDI PENYERAPAN AMONIAK DARI LIMBAH PABRIK KARET
DENGAN MENGGUNAKAN ZEOLIT ALAM SERTA PEROLEHAN
KEMBALI (RECOVERY) AMONIAK YANG
TELAH DISERAP ZEOLIT
ABSTRAK
Telah dilakukan studi penyerapan amoniak dari limbah pabrik karet dengan menggunakan zeolit alam serta perolehan kembali (recovery) amoniak yang diserap oleh zeolit. Sampel diambil dari limbah cair buangan pertama dari salah satu pabrik karet yang terdapat di Kisaran. Serbuk zeolit 100 mesh diaktivasi pada
suhu 250oC selama 3 jam dan divariasikan beratnya 2,0 ; 4,0 ; 6,0 ; 8,0 ; 10,0
gram. Penentuan Amoniak dilakukan dengan metode Nessler secara spektrofotometri pada panjang gelombang maksimum 410 nm. Dari hasil penelitian diperoleh Persen penyerapan amoniak oleh zeolit aktif 2,0 ; 4,0 ; 6,0 ; 8,0 ; 10,0 gram masing-masing adalah 62,1353% ; 65,5407% ; 68,8344% ; 70,9870% ; 72,5635%, dan persen recovery amoniak masing-masing adalah 38,4708% ; 38,2071% ; 34,8923% ; 35,1802% ; 33,2155%.
THE STUDY ON AMMONIA ABSORPTION FROM WASTE RUBBER FACTORY WITH USE NATURAL ZEOLITE AND AMMONIA
RECOVERY WHICH HAS BEEN ABSORBED BY THE ZEOLITE
ABSTRACT
The study on ammonia absorption from waste rubber factory with use natural zeolite and the recovery of ammonia that absorbed by zeolite has been conducted. Sample was taken from the wastewater effluent from one of rubber factory located in Kisaran city. The powder of 100 mesh activated zeolite was produced by
heating the powder at 250oC for three hours. Determination of ammonia was
performed spectrophotometrically with Nessler Method at the maximum wave-length of 410 nm. The result of analysis of this study obtained that percent of ammonia absorption with the activated zeolite 2,0 ; 4,0 ; 6,0 ; 8,0 ; 10,0 gram 62,1353% ; 65,5407% ; 68,8344% ; 70,9870% ; 72,5635% respectively and percent of ammonia recovery 38,4708% ; 38,2071% ; 34,8923% ; 35,1802% ; 33,2155% respectively.
