  Removal of Pb (II) Ions from Aqueous Solution and Industrial Wastewater using Activated Carbon Prepared from Flax Straw
  Author(s): Tayto Mindahun*
  
  This study aimed to prepare AC from flax straw and investigate its potential for the removal of Pb (II) ions from aqueous solution and real industrial wastewater. AC was prepared by chemical activation method using H3PO4 as activating agent. The effects of initial Pb (II) ion concentration, adsorbent dose, contact time and pH on the removal efficiency were studied by using aqueous solution prepared from Lead nitrate (Pb (NO3)2) on a batch mode. Response surface methodology was used in order to carry out experimental runs. The collected wastewater sample was characterized before and after treatment according to APHA methods. Activated carbon was characterized and results showed that the flax straw AC had 8.04% of moisture, 6.04% of ash, 18.615% of volatile matter, 79.421% of fixed carbon, 459.807 mg/g of iodine number and ..
