Abstract

Cu,Pb,Zn and Ni of the industry sludge were determined by FAAS.The limits of examined elements was 0.01～0.10 mg/L.The relative standard deviatations were 2.73%～4.46%,and the recoveries for six elements were between 97.0%～105.0%.The method is high accuracy and good precision and has been applied to the determination of standard and actual samples with satisfactory results.
