THE PEROXYMONOCARBONATE ANIONS AS PULP BLEACHING AGENTS. Part 2. MECHANICAL PULP BRIGHTENING AND EFFECTS OF METAL IONS
PEROXYMONOCARBONATE ANIONS PULP BLEACHING AGENTS
2010/10/25
The peroxymonocarbonate mono-anion (HCO4─) is generated in solutions containing bicarbonate anions (HCO3─) and hydrogen peroxide (H2O2). The mono-anion is believed to have a pKa value of ca. 10 and as...
