Sintesis dan Karakterisasi Morfologi dan Termal Membran Komposit Kitosan-Zeolit Alam Bayah
Abstrak
Membran berbahan dasar alam telah banyak dikembangkan dalam rangka mendukung green chemistry. Artikel ini memaparkan hasil penelitian mengenai sintesis dan karakterisasi membran komposit kitosan dan zeolit. Penelitian ini bertujuan untuk mengetahui pengaruh variasi berat zeolit terhadap sebaran zeolit pada film membran kitosan serta pengaruhnya terhadap suhu dekomposisi membran. Zeolit yang digunakan dalam penelitian ini adalah zeolit alam bayah. Sintesis dilakukan dengan melarutkan kitosan dalam asam asetat, kemudian dikompsit dengan zeolit alam dengan variasi kadar berat terhadap kitosan 5%, 10% dan 15%. Karakterisasi dilakukan dengan metode analisis SEM-EDS dan TGA-DTA. Dari hasil karakterisasi didapatkan bahwa sebaran zeolit yang optimum adalah pada penambahan zeolit 5%.Unduhan
