Özet
The leaching of lead from the treated anode slime with
triethanolamine (TEA) was investigated by using full factorial and orthogonal
design techniques. The effects of TEA concentration, solid/liquid ratio,
temperature, and contact time on the leaching process were evaluated to
determine the interactions between the parameters. The major factors for the
system were found to be TEA concentration and reaction temperature. The highest
recovery is obtained at process conditions of 3.5 M TEA concentration, reaction
time of 150 min, solid/liquid ratio of 1/10, and a temperature of 313 K. A
polynomial model between the important parameters and response was deduced
using variance analysis at 95 % confidence level. The analytical performance
for measurement at the point of optimum by this technique was found to be
superior and more proper than that of one variable at a time
