ABSTRACT
Background:
The aim of this study is to statistical modeling of lead (Pb) adsorption on Van Pumice. Van Pumice was used for determination of lead (Pb) adsorption level.

Material and methods:
Modeling, depending on time, was performed to determine for lead (Pb) adsorption level at fixed pH 5.5 for various concentration and temperatures in Van pumice. All adsorption measurements were performed with the Thermo Scientific brand ICE spectrometer model 300 Series. One-way analysis of variance was used for comparison to various temperature and concentration levels. Tukey’s multiple comparison test was also performed to determine different groups. Logarithmic, quadratic, cubic and logistic models as well as linear were used to determine adsorbed lead (Pb) amount at different temperature levels and heavy metal concentration.

Results:
Differences between various time and concentration levels were found statistically significant; however, there were no significant differences between temperature and concentration levels. In addition, cubic model had higher R2 values for each concentration and temperature levels. Lead (Pb) concentration and amount of ions have been increased in the solution.

Conclusions:
As a result, although all models were significant, cubic model showed the best performance.
