Investigation on the Application of the Organic Complex " Sulvy-x " in Peroxide Bleaching of Hornbeam CMP Pulp

In this study, the effect of organic complex "sulvy-x" on the optical properties of hornbeam CMP pulp bleached with hydrogen peroxide was investigated. Sulvy-x was used in two sequences silicate-free and silicate containing in hydrogen peroxide bleaching. The brightness of papers increased...
