Paper Title:
Characterization of Rice Husks of Pyrolysed at 320°C and Adsorption Ni2+ Ions
  Abstract

Characterization of rice husks (RHs) of pyrolysed partly at 320°C and adsorption Ni2+ ions in the NiSO4 solution and the wastewater of electroless nickel plating on magnesium alloys were investigated. The morphology of partly carbonized rice husks(PCRHs)was porous and particles and it consisted of amorphous carbon and silica. Thermogravimetric(TG) curve showed that rice husks mass decreased sharply at 280°C until 360°C. Raw RHs and PCRHs had good adsorption of Ni2+ in the NiSO4 solution or wastewater of electroless nickel plating on magnesium alloys. Removal capacity of Ni2+ was higher for PCRHs than that of RHs due to PCRHs were mainly microporous with narrow pore size distribution.
