ABSTRACT
Industrial waste water samples were collected from the
drains of 1lI’0 factories. Egyptian Company for Plastic Industries
and Batteries Production and EI-Beda Dyers Company. The waste
waler qualiTy were determined. Cementation reactions were
jollowed on filtered samples under reaction conditions 700 rpm,
./0 ce. 7 hour reaction period and exposed swiace area of Zn
cylinder were ./7.13 cn/. ./9.76 cn/ for the two .samples oj the
1l1’O Slations respectively. Cementation reaction rale of Cu -} and
Pb -2 in each sample were estimated where. 94.5% oj copper and
96.5% of lead were recovered from the waSle water of the
Egyptian Company for Plastics Indusf.1’ies and Batteries
Production and 88.7% of copper and 82% oj lead were
recovered from El-Beda Dyers Company
