The ability of atrazine to interact with several metals was investigat
ed by means of synergistic liquid-liquid extraction. For that purpose,
the extraction of cadmium, copper, lead and zinc by yl-3-methyl-4-p-t
ertbutylbenzoyl-5-hydroxypyrazole (HL) in chloroform was studied in th
e presence of atrazine (ATR). This pesticide enhanced the extraction o
f these metals in the order Cd>Zn>Cu through the formation of a ML2(AT
R) complex. However, no influence of atrazine was observed on the extr
action of lead. (C) 1998 Published by Elsevier Science B.V. All rights
