Pemutihan Pulp Dengan Hidrogen Peroksida

Abstract: The use of bleaching agent has increased as the result of increasing of paper consumption. The conventional bleaching agent that commonly used is material containing of chlorine. This material is not environmentally friendly and should be replaced by environmentally benign chemical, such as H2O2. About 40 gram of dry Akasia pulp was mixed with 600 ml of distilled water was put into plastic bag heated in a water bath. When the temperature reached 630C, a solution of 4 % of H2O2 and distilled water was added to … Show more

“…Kondisi tersebut saat ini mulai dirasakan oleh sebagian industri pulp dan kertas. Ketika permintaan kertas mengalami peningkatan sekitar 3,5% per tahun (Fuadi & Sulistya, 2008), ketersediaan bahan baku berupa kayu justru tidak meningkat bahkan cenderung semakin terbatas. Oleh karena itu perlu alternatif pengganti bahan baku kayu untuk industri pulp dan kertas yang mempunyai nilai ekonomi rendah.…”

“…Peruraian hidrogen peroksida juga dipercepat oleh naiknya suhu. Zat reaktif dalam sistem pemutihan dengan hidrogen peroksida dalam suasana basa adalah perhydroxyl anion (HOO-) (Fuadi dan Sulistya, 2008). Proses pemutihan menggunakan peroksida biasanya dilakukan kisaran waktu 30 menit hinga 4 jam.…”
