用水冶法从富铊灰中回收铊时,由于烟尘中铊主要以低价化合物存在,以致硫酸浸取液中的金属和非金属离子多处于低价状态,征含砷(Ⅲ)量往往较高的复杂体系
When water is used to recover thallium from a thallium-rich ash, the amount of arsenic (III) in the leachate tends to be lower because the thallium in the soot is mainly present as a low-valent compound, resulting in that metals and non-metallic ions in the sulfuric acid leaching solution are mostly in a low- High complex system
