Among some kinds of agricultural wastes such as orange skin, pagoda tree bark, Gracilaria, Huashan pine bark, Huashan pine cone, Huashan pine needle, Cedar needle, Tasson leaf, in this study, Huashan pine cone was screened as the most efficient adsorbent material to remove toxic Cr (VI) from aqueous solution. Adsorption experiments showed that pine cone powder was a good adsorbent for Cr(VI), under the condition of the temperature 30oC, adsorbent dosage 3 g/L, particle size 120 mesh, Cr (VI) concentration about 50 mg/L, Cr(VI) removal rate reached 100% within 15 minutes at pH ≤ 2, which reaching 80.6% within 2 hours at pH = 3. Electroplating wastewater treatment tests showed that pine cone was a good adsorptive material, the effluent heavy metal ion concentration can achieve the first discharge standard by controlling the adsorption conditions.
