Pengaruh Waktu terhadap Bilangan Kappa dan Brightness dari Proses Unbleach Blending ke Proses Bleaching D0 Stage Di Pt. Toba Pulp Lestari, Tbk Porsea

Abstract

Analysis Number of kappa in PT.TOBA PULP, Tbk PORSEA conducted with titration method. At this method of mixed with pulp is KMnO4 0,1N counted 50 ml, H2SO4 4N 50 ml, KI 10 ml and by using Na2S2O4 as titration. The condensation enhanced with indicator of amilum for quicken reaction. Till finally transparent condensation and can be determined by value of number of kappa. While analysis of brightness conducted with computer system by using appliance of called ELREPHO R457D65.
