采用分批和柱实验方法，研究了由粘结材料粘结的氧化铁颗粒组成的颗粒吸附剂去除水中铅离子的能力。结果表明，去除的最佳pH值在5到7之间。批处理和柱状研究得出的结合常数值相似——约为5-5，但柱状研究表明，吸附剂的容量明显更大，其值为4.3 mg Pb/g。吸附剂的再生可以通过用酸性溶液（pH=3）冲洗来实现，尽管在长时间的吸附过程中，由于不完全解吸，可能会在孔隙中积聚一些残余铅。包括27个参考文献、表格和图表。

A granular adsorbent consisting of iron oxide particles cemented by a binding material was investigated for its ability to remove lead ion from water using both batch and column experimental methods. Results showed the optimum pH for removal to be between 5 and 7. Both batch and column studies yielded similar values for the binding constant--about 5-but column studies indicated a significantly larger capacity, with a value of 4.3 mg Pb/g of adsorbent. Regeneration of the sorbent can be achieved by flushing with an acidic solution (pH = 3), although for long adsorption runs some buildup of residual lead within the pores is possible as a result of incomplete desorption.
