Corn Stalk (CS) modified by urea and microwave was investigated as an adsorbent for Pb(Ⅱ) removal from aqueous solution. The preparing parameters on mass percent gain of Modified Corn Stalk (MCS) are analyzed using response surface methodology (RSM).The effects of PH and MCS dose on the Pb (Ⅱ) removal process were studied by using batch methods. The maximum adsorption capacity of Pb (II) onto MCS was found to be 12.78 mg/L. The adsorption isotherms were analyzed using the Langmuir anddoi:10.2991/cmes-15.2015.16 fatcat:g7gntjlqhnekhftqknqf6htr6i
