Abstract:

For dyes and Cr (VI) stripped from metallic roller in the printing process, two new adsorbents, nanoscale zero-valent iron (GS-NZVI) and nanoscalezero-valent iron supported on expanded graphite (GS-EG-NZVI) were green-synthesized. The two adsorbents were characterized by field emission electron microscopy, energy dispersive spectrometer, X-ray diffraction, etc. GS-EG-NZVI was investigated on the removal of Cr(VI) and dyes of aqueous solution, and on the corresponding dynamics and stability. Results indicated that nanoscalezero-valent iron was successfully loaded on the surface of EG with good dispersion. For the aqueous solution including 50 mg/L Cibacron Dark Blue and 20 mg/L Cr (Ⅵ), addition of 2.5 g/L GS-EG-NZVI led to the achievements of the removal rates of 90.6% of dyes and 53.6% of Cr (VI) respectively under the conditions of at 50 ℃, pH=2, 35 min reaction time with ultrasound assistance. The two removal processes fitted well with the pseudo second-order dynamic model. GS-EG-NZVI showed higher potential for removing Cr(Ⅵ) in aqueous solution than GS-NZVI due to its high stability after being placed in the air for different time.
