- 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.
