摘要
以硫化钡卤为沉淀剂,采用化学沉淀法,通过合适的工艺配比在硫化钠浓卤中处理碳酸根离子,可使成品硫化钠中碳酸钠含量降到1.0%以下。
Carbonic ion in concentrated sodium sulfide can be precipitated by adding barium sulfide precipitating agent with a certain proportion.As a result,the content of sodium carbonate in the sodium sulfide product can be decreased to less than 1.0%.
