Abstract
Used newsprint is one of the most potential materials to be recovered into pulp raw material. The problem is the color of newsprint that requires bleaching process. One of the oxidizing agents used for bleaching is the peroxide acid in the acetic acid medium. The purpose of this research is to know the effect of peroxide acid concentration in acetic acid media and the duration of heating to the chemical properties of pulp produced. The best results were obtained at 12% per oxide acid concentration in acetic acid medium and 5 hour heating time, yielding 58.653% cellulose, hemicellulose 9,033%, lignin 22,683%, and color score 4,503% (rather white).
Highlights
Pembuatan pulp dan kertas di Indonesia menggunakan kayu hutan seperti pinus sehingga menimbulkan banyak masalah terutama penggundulan hutan dan isu pemanasan global serta semakin menipisnya cadangan kayu dan luas hutan di Indonesia (Deperindag dan APKI, 2001, Barr, 2001; Arifin, 2008; Madakadze et al, 1999; Aremu et al, 2015)
