Jayanti, Luh Putu Saraswati Devia (2019) Modifikasi Membran Selulosa Ester dengan Impregnasi Filler Glukomanan Hasil Isolasi Tepung Porang (Amorphophallus Muller Blume). Sarjana thesis, Universitas Brawijaya.
Abstract
Studi impregnasi (wet vaccum impregnation) membran selulosa ester menggunakan suspensi filler glukomanan (glukomanan : air adalah 1:10) untuk memodifikasi karakter membran serta mengkaji potensinya untuk memisahkan garam NaCl dan MgCl2 telah dilakukan. Ketebalan membran selulosa ester termodifikasi yang dihasilkan adalah 0,014 – 0,015 cm. Sedangkan pengukuran porositas berdasarkan perbandingan densitas dimensi dengan piknometer menghasilkan nilai porositas terbesar 0,0306. Pengujian sudut kontak untuk mengetahui sifat hidrofobisitas menghasilkan nilai sudut 43- 65°. Pengujian dengan bubble point untuk mengetahui ukuran pori maksimal menunjukkan bahwa membran memiliki ukuran pori ± 1
English Abstract
The study of cellulose ester membranes modification with wet vaccum impregnation using glucomannan filler suspension (glucomannan: water is 1:10) to modify the character of the membrane and assess its potency to separate NaCl and MgCl2 salts, has been carried out. The thickness of the modified cellulose ester membrane produced is 0.014 - 0.015 cm while the porosity measured (based on the ratio of dimensional density and with picnometer) is 0.0306 at highest. Experiment with contact angle to determine the nature of membrane hydrophobicity results in an angle value of 43-65°. Experiment with bubble point to determine the maximum pore size indicates that the membrane has a pore size of ± 1
