Penelitian ini mengenai analisis nanokristal selulosa dilakukan secara laboratorium. Penelitian ini dilakukan untuk mendapatkan informasi karakterisasi nanokristal selulosa hasil isolasi dari tandan kosong sawit. Tahap awal yaitu isolasi α-selulosa dari tandan kosong sawit (TKS) melalui proses dilignifikasi dengan menggunakan HNO3 3,5 dan NaNO2, kemudian peoses pulping dengan NaOH 17%, dan pemutihan dengan H2O2 10%. Tahap selanjutnya yaitu isolasi Nanokristal selulosa dari α-selulosa dilakukan dengan hidrolisis asam, yaitu dengan menggunakan asam sulfat 48,84%, yang kemudian didialisis hingga diperoleh nanokristal selulosa. Nanokristal selulosa yang dihasilkan dikarakterisasi gugus fungsinya dengan menggunakan FT-IR, dan kemudian analisis morfologi dan ukuran dengan menggunakan TEM. Ukuran nanokristal yang dihasilkan yaitu 47,46 nm.References
