摘要:
为了抑制镀铬工业中产生的铬酸雾,分别利用腈纶基弱碱型离子交换纤维和脱脂棉对铬酸雾进行了吸附研究.结果表明:弱碱离子交换纤维连续使用150 h吸附铬酸雾1.26 mg,且尾气浓度低于0.005 mg/m3,远低于国标规定的铬酸雾排放标准(0.05 mg/m3)；脱脂棉在连续使用55 h后尾气排放超标,尾气浓度为0.069 mg/m3；通过4次再生吸附实验,弱碱离子交换纤维保持了良好的吸附与机械性能,在含铬废气治理中有很好的应用前景.
Abstract:
In order to restrain the chromic acid waste gases diffuse from electroplating bathes,the adsorptionproperties of anion exchange fiber and adsorbent cotton were investigated in this paper. The results show thatthe anion exchange fiber can take up 1.26 mg chromic acid mist in 150 h. The concentration of chromic acidin the end gas is lower than 0.005 mg/m3, which is far below the national standard 0.05 mg/m3for chromicacid mist emissions. The adsorbent cotton was broken through after continuous used 55 h. The concentration ofchromic acid mist in the end gas was up to 0.069 mg/m3. So the anion exchange fiber has a good applicationprospect for chromic acid mist treatment in electroplating industry.
