Abstract:
Ultra trace amounts of heavy metals, such as Cu, Pb, were determined by graphite furnace-atomic absorption spectrophotometry (GF-AAS) after miniature membrane filer (MF) concentration/dissolution. Heavy metals were concentrated as pyrrolidine-dithiocarbamate (APDC) chelates on a miniature MF of which diameter was 5 mm, effec-tive filtering diameter was 2 mm and pore size was 2 μm.
