Adsorption of Cr (VI) from Simulated Wastewater onto Tannin-Immobilized Bentonite

摘要：

Tannin-immobilized bentonite was used to remove Cr (VI) from electroplating wastewater in this study. The adsorption characteristics of Cr (VI) on the modified bentonite were investigated, including the effects of pH, adsorbent dosage, initial concentration of Cr (VI), temperature and on removal of Cr (VI) by conducting a series of batch adsorption experiments. The results showed that 100％ of Cr (VI) removal rate was obtained since adsorbent used in this investigation were abundantly and locally available. It is concluded that tannin-immobilized bentonite is a relatively efficient, low cost and easily available adsorbent for the removal of Cr (VI) from laboratory simulated electroplating wastewater.
