Abstract : Synthetic dyes are widely used in several industries particularly for textile, tannery, paper, plastics, pharmaceutical, and food industries. The effect of different experimental conditions such as time, dye concentrations, contact time and adsorbent amount has been investigated. The aim of this study is to investigate the adsorption of malachite green dye ions from aqueous solution on montmorillonite clay using 23 full factorial design. The combined effect of initial metal concentration, adsorbent amount and contact time on the malachite green dye adsorption was studied. Factorial design of experiments is employed to study the effect of three factors initial malachite green dye concentration (20 and 200 mg/L), adsorbent dosage (0.1 and 1 g/100ml) and contact time (5 and 240 min.), at two levels low and high. The results were statistically analyzed by using the student’s t-test, analysis of variance (ANOVA) and an F-test to define important experimental factors and their levels. A regression model that considers the significant main and interaction effects was suggested. The results showed that initial dye concentration is the most significant factor that affects the removal of malachite green dye ions Keywords— Malachite Green, Adsorption, Montmorillonite Clay, Sand, Full Factorial Design.
