摘要
研究表明,地表水中痕量铊基本上是以溶解态存在,难以自然沉降。本文采用硫化钠和石灰作为沉淀剂,处理受铊污染的地表水,实验表明该方法可快速有效沉淀处理地表水中痕量铊,适用于地表水铊污染事件的应急沉淀处理。
Trace thallium in surface water is present as soluble speciation,and is diilicult to be precipitated with the suspended solids. By using sodium sulphide and lime as preeipitants, the trace thallium in surface water can be precipitated quickly, suitable for the urgent treatment of thallium polluted surface water.
