摘要：
The pretreatment of ground calcium carbonate (GCC) with 0.2 g/g GCC of H3PO4 and its application is described. When pretreated GCC was added to a mechanical pulp suspension, the dissolved calcium concentration was less compared to that of untreated GCC. Handsheets with pretreated GCC were prepared. It was found that the pretreatment slightly increased the brightness, scattering coefficient and filler content of sheets but the absorption coefficient decreased.
