摘要
The method for determination of total heavy metal residues on Eco textiles has been developed on the basis of Eco Tex standards.Samples were treated in H 2SO 4 HNO 3 HClO 4,extracted and enriched by chaleting agent C 5H 12 N 2S 2 and organic solvent acetic ester,and finally tested by AAS for Cu,Co,Ni,Cd and Pb residues.The liner regression is more than 0.999 for all elements tested.The LODs(limits of detection) are less than 0.05mg/kg,Recoveries are between 95～102%,RSDs lie in 1.37 to 3.92%.
