Sintesis Zeolit4 Adengan Metoda Konversi Hydrothermal Kaolin
Abstract: The synthesis of
zolite 4A from kaolinite has been done. The synthesis was carriedout by mixing
of kaolinite and sodium hydroxide inaqueous solution for 8 hours,then the
solution was crystalized at 100oC for 8 hours. The product was washed outuntil
neutral pH and followed by drying at 120oC for 3hours. The product was
thencharacterized by using infrared spectrophotometry and x-ray difractometry.
Somephysical parameter of the reaction, those are the variation amount of
sodiumhydroxide (10/4; 10/6; 10/8; and 10/12) , time of gel formation, and
particle size ofkaolinite (100, 200, and 400mesh). To obtain more crystallinity
of zeolit 4A, theeffect temperature gel formation at 70 oC by mixing 3 hours have
also beenstudied. The results show that the zeolite 4A can be obtained in the
ratio 12/10 ofkaolinite to sodium hydroxide and temperature gel formation at 70oC.
