his research study is divided into two parts; the first part

investigates the batch ETL dye sorption by Arundo-donax.

The sorbent was synthesized and characterized by scanning

electron microscope (SEM) and Fourier transform infrared

spectroscopy (FTIR). The effects of pH, initial dye concentration,

contact time and mass sorbent in the efficiency of ETL sorption

were investigated. Furthermore, pseudo-first and second-order

kinetic models were also used to analyze sorption kinetics. The

equilibrium adsorption results were fitted by the Langmuir and

Freundlich isotherms. Maximum amount ETL removal 56.49

mg/g was observed at pH 2, sorbent weight 50mg and contact

time 60min.

In the second part the aimwas to evaluate the impact of operating

conditions in the efficiency of Arundo-donax to remove ETL dye.

From the first part, three factors were chosen (initial solution

concentration of ETL, pH solution and Arundo-donax weight).

These factors were investigated using three level box behnken

design to optimize operating conditions. Analysis of variance

(ANOVA) were using to testing the obtained linear model. The pH

solution and initial dye concentration have an important effect

compared to the effects of others factors. Correlation coefficient

was found 0.99, which mean the accordance between the

model and the experiment data.
