过去曾发表过“铀矿酸浸取液中硅酸状态的测定”一文,其中γ硅酸是用差减法测定的。该法虽然测定速度较快,但易引起误差。重量法是测定硅酸常用的分析方法,它是将硅酸在8N 以上的盐酸介质中转化为带阴电荷的γ硅酸,以动物胶凝聚,灼烧称量而测定的。以此常量分析的原理,用于微量分析,特别是用于不同状态硅酸的分离研究,虽有报道,但未见详细资料。本文叙述了利用γ硅酸与动物胶凝聚的性质,将γ硅酸与α、β硅酸分离,进而测定γ硅酸的方法。
In the past has published “uranium acid leaching solution Determination of silicic acid state ” article, which y silicic acid is determined by the subtractive method. Although the method of determination of speed, but easy to cause errors. Gravimetric method is commonly used in the determination of silicic acid analysis method, which is the silicic acid in hydrochloric acid above 8N medium into a negative charge of γ silicic acid, animal glue agglomeration, ignition and measured. The principle of this constant analysis for trace analysis, especially for the separation of different states of silicic acid research, although there are reports, but no detailed information. This article describes the use of γ silicic acid and animal glue aggregation nature of γ silicic acid and α, β silicic acid separation, and then determine γ silicic acid method.
