| 摘 要： | 研究了黄磷尾气解毒铬渣。实验方法及工艺条件：将六价铬（铬酸钠）质量分数为1%的铬渣粉碎至粒度小于75 μm，取5 g样品加入石英管中，加热到600 ℃，反应20 min，然后在黄磷尾气气氛中冷却至200 ℃以下。实验结果表明，在上述条件下可以将铬渣中六价铬质量分数降至0.3 mg/kg，并且铬渣不会返黄。

| Abstract: | The detoxification of chromium residue using yellow phosphorus tail gas was researched. Experimental approach and process conditions: chromium residue， which contained 1% Cr（Ⅵ）［w（Na2CrO4）］，was crashed to 75 μm below.Then，
5 g sample was took into quartz tube，reaction occurred in 600 ℃ for 20 min，and reactants was protected in yellow phosphorus tail gas till to cool below 200 ℃.Experiment results showed that，Cr(Ⅵ) in chromium residue could be reduced to 0.3 mg/kg，and had none brightness reversion phenomenon. |

| Keywords: | chromium residue detoxification yellow phosphorus tail gas solid waste gas waste |
