【摘要】 研究了玉米食用部分之外的玉米芯吸附冶炼废水中铅的条件。室温下,pH为5.0,吸附时间60min,玉米芯的饱和吸附量为:31.7mg/g。同时,研究了酸度、吸附时间、吸附剂粒度、流速等条件对铅去除率的影响。并用研制的吸附剂处理冶炼厂的废水,处理后废水中铅含量显著低于国家标准允许排放浓度。更多还原

【Abstract】 The adsorption of lead ions from waste water by com kernel,Which residual parts of eaten corn and ground to make powder.The research indicated that the material has strong adsorption capacity to the lead from the solution.The absorbance(mg/g)reaching equilibrium state is 31.7,respectively.The waste water from metal-finishing industry was treated by the paepared adsorbents.And the residual lead concentration was much less than the allowed standard according to the GBJ4-73.更多还原
