THE PEROXYMONOCARBONATE ANIONS AS PULP BLEACHING AGENTS. Part 2. MECHANICAL PULP BRIGHTENING AND EFFECTS OF METAL IONS
Attiogbe, Francis K - Wang, Wei - McNeillie, Alastair - Francis, Ray C.

Formato:	info:eu-repo/semantics/article, info:eu-repo/semantics/publishedVersion
Enlaces:	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 such would start dissociating to the di-anion (CO42─) at pH…
