Abstract:
An absorbent for lead removal was prepared by a direct shaping method without any calcined process using oyster shell as a main raw material and Portland cement as a binder. The effects of raw material composition, initial lead concentration and pH value in waste water on the lead removal efficiency were investigated to determine the suitable conditions for lead removal. The microstructure of the samples before and after lead removal was analyzed by scanning electron microscopy. The results show that the bending strength of adsorbent sample is 11.26 MPa, and the lead removal efficiency can reach 90% at pH value of 5 when the optimum raw material composition is oyster shell powder of 90% and Portland cement of 10%. The lead absorption mechanism with the oyster shell materials belongs to both physical and chemical adsorptions.
