Effect of Solid Phase Extraction Column Packing Material On Solid Waste Metallic Ion Separation
Ten metallic ions including Be,As,Se,Cd,Cu,Zn,Ba,Cr,Ni,and Pb in the solid waste samples were separated by Solid phase extraction columns,and tested by an inductively coupled plasma emission spectrometer and an inductively coupled plasma mass spectrometer.Results showed that:the solution pH value was about 1,each element could be quantitatively recovered on the packing material;Metallic ions could be eluted using 3 mL of 3 mol/L nitric acid.The adsorption capacity of the packing material is 0.28mmol(Cu)/g dry packing material.This method was applied to MSWI Fly Ash Solidification Wastes and MSW incinerator residue,testing 10 elements including Be,As,Se,Cd,Cu,Zn,Ba,Cr,Ni and Pb,and the results meet the standard requirements.
