Abstract
Delignifikasi oksigen (peringkat-O) adalah pringkat yang paling penting (selaku peringkat pertama) dalam turutan pelunturan bebas-klorin untuk penyingkiran lignin secara pukal, jadi, pemaksimuman kepilihan serta kecerahan pulpa pada peringkat-O adalah mustahak.
Oxygen delignification (O-stage) is the most important stage (as first stage) in chlorine-free bleaching sequence to remove lignin in bulk, thus, maximizing of O-stage bleaching selectivity as well as pulp brightness is essential.
