چکیده

Pengubahsuaian kimia terhadap selulosa tandan kosong kelapa sawit (TKKS) menggunakan agen pengesteran asid etilena diamina tetraasetik (EDTA) dan asetik (AA) dengan parameter yang berbeza dikaji dioptimumkan. Pada peringkat awal, pulpa TKKS telah dirawat empat pelunturan (D-E-E-D) untuk menghasilkan TKKS. Seterusnya, melalui proses esterifikasi AA EDTA dibantu oleh sistem pemanasan gelombang mikro bagi tujuan penambahbaikan keberkesanan pengesteran. Pengaruh pra-rawatan kestabilan termal perubahan kumpulan berfungsi dioptimumkan reka bentuk komposit pusat (CCD), pemodelan permukaan tindak balas (RSM) diikuti analisis termogravitometri (TGA) (FT-IR). Didapati terdapat perbezaan ketara (produk esterifikasi) berlaku kepada diubah suai berbanding pada suhu tinggi. Data RSM menunjukkan suhu, masa, kepekatan bahan selulosa-AA adalah 90 °C, 46 min 8.18, manakala selulosa-EDTA 100 70 0.7. Berdasarkan CCD, keputusan bahawa rawatan lebih baik AA.
