Abstract:

The objective of this research is removal of Acid Red 151(A.R.151) from aqueous solutionusing palm shell as low-cost adsorbent. The operating parameters such as pH solution, doseof adsorbent, initial dye concentration were investigated. Results showed that pH: 3, dose ofadsorbent: 2g/L and initial dye concentration: 20mg/L were the most suitable. In this study,the best fit of the adsorption isotherm data was obtained using the Langmuir model and showfavorable adsorption of A.R.151 dye with separation factor (0 < RL < 1).
