摘要

研究了花生壳作为改性农用吸附剂对金属电镀废水的脱除效果。研究了不同吸附剂参数对金属电镀废水中锌的吸附性能。考察了pH、吸附剂剂量、接触时间、初始锌浓度和温度等参数对MPE吸附性能的影响。在pH为3.5、时间为250 min时,锌的去除率最高为75.85%。吸附后得到的污泥经过滤后干燥,可作为燃料在锅炉炉膛中使用。

Expulsion of Zn from the Downstream of Metal Plating Effluent onto Modified Agricultural Adsorbent Prepared from Peanut Shell
Present work deals with the removal of Zinc (Zn) from metal plating industry effluent (MPE) using peanut husk as a modified agricultural adsorbent (MAA). The adsorption of zinc from metal plating effluent has been investigated along with various adsorbent parameters. The MPE was investigated for various parameters like pH, adsorbent doze dose, contact time, initial zinc concentration and temperature. The maximum removal efficiency of zinc was found to be (75.85 %) at pH 3.5 and time 250 min). The sludge obtained after adsorption has been filtered followed by drying which can be used in a boiler furnace as a fuel.
