ADSORPTIVE REMOVAL OF BRILLIANT GREEN DYE FROM AQUEOUS SOLUTIONS USING CEDAR AND MAHOGANY SAWDUSTS
The objective of this study is the valorization of industrial wood wastes and their application in the adsorption of a cationic dye “Brilliant Green (BG)” in solution. These experienced natural wastes are Cedar and Mahogany sawdusts, which are part of the range of abundant and inexpensive lignocellu...

| description | The objective of this study is the valorization of industrial wood wastes and their application in the adsorption of a cationic dye “Brilliant Green (BG)” in solution. These experienced natural wastes are Cedar and Mahogany sawdusts, which are part of the range of abundant and inexpensive lignocellulosic products that can replace the conventionally used materials such as charcoal, silica gel and alumina. The results of the adsorption tests of Brilliant Green, show that under appropriate conditions, the adsorption rate is about 89 % on Cedar and 80 % on Mahogany sawdusts, for a concentration of 100 mg·L-1 of dye, by adding 8 g·L-1 of cedar and 20 g·L-1 of Mahogany as optimal doses of adsorbents, during a contact time of 40 min and at room temperature. The modeling of adsorption isotherms obtained is consistent with the Langmuir model. The kinetics data indicate that the process of Brilliant Green adsorption on both sawdusts follows the pseudo second order model. According to this study, these sawdusts are very effective in sorbing the BG and which could be used for the removal of other cationic dyes. |
