When people think of factories, they think of clouds of dirty smoke or a pipe pouring chemical waste into a river. They think of greedy businessmen hiding from their responsibilities to the environment and only thinking about money.

每当人们想起工厂，他们就会联想到滚滚烟尘，或者一根向河中倾泻化学废物的管道；他们就会联想到贪婪的商人躲避自己对环境的责任、一味追求金钱。

The dust was first mixed with NaBH4 powder to adjust the H/Cl ratio. Then, the sample was roasted at low temperature to promote the efficiency of dehalogenation/hydrogenation reaction. By way of Cl- titration, it was found that the roasting temperature (300℃~500℃), roasting time (5 to 25 minutes) and H/Cl ratio (6.0 to 20.0) would change the dissolution of Cl- from 0.0% to 17.5%. After caustic roasting and leaching of the dust, the zinc (17.4 g/l) and lead (1.6 g/l) recovery ratio were found to be 82.7% and 61.8% respectively.

利用NaBH4在低温可促进氯化冶金反应的进行，经由氯离子浓度滴定，发现随著焙烧时间、温度及H/Cl比值之调整，氯离子之溶出量变化亦相对改变，此结果说明在使用NaBH4调配H/Cl比值由6.0~20.0的变化下，烟尘中的氯成分在低温(300℃~500℃)焙烧5~20分钟，可与金属氧化物发生氯化反应，氯离子溶出量显示有0~17.5%不等之变化量。
