Studies on microwave digestion procedures for the simultaneous multielement determination of arsenic, antimony, chromium, cadmium, nickel, and lead in municipal waste incineration fly ash by ICP-AES

摘要

Microwave digestion (MWD) with two kinds of acid mixtures (HCl-NHO_3-HF, HclO_4-HNO_3-HF) was investigated for the simultaneous determination of six toxic ele- ments (Arsenic, antimony, chromium, cadmium, nickel, lead) in municipal-waste incinera- tion fly ash (MWIFA) using inductively coupled plasma atomic-emission spectrometry (ICP)-AES).
