摘要：

Ground quartz, pretreated with HF, was shaken with buffer of pH 7·7 at 25°C. Suspensions, with and without added monosilicic acid, gave the same steady monosilicic acid concentration viz. 18-20 ppm SiO2. Quartz samples which were contaminated with Al generally failed to establish steady concentrations of monosilicic acid. © 1969.
