Paper Title:
Comparison of Digestion Methods for Analysis of Heavy Metals in MSWI Bottom Ash
  Abstract

This work aims to develop a proper digestion method for measurement of heavy metal content in municipal solid waste incineration (MSWI) bottom. Different digestion methods by HNO3, HNO3/HCl, HNO3/HCl/HClO4, HNO3/HCl/H2O2, HNO3/HClO4, HNO3/H2O2, were compared in digestion efficiency, and Cu, Pb, Zn and Cd were analyzed using atomic absorption spectrum (AAS). The method using mixed HNO3/HCl/HClO4 was recommended for digestion of MSWI slag for measurement of Cu, Pb, Zn, and the method of HNO3/H2O2 recommended for digestion for measurement of Cd.
