KINETIC MODEL FOR THE REMOVAL OF MALACHITE GREEN (DYE) FROM AQUEOUS SOLUTIONS USING PALM KERNEL SHELL
Journal Title: World Journal of Pharmaceutical and life sciences - Year 2017, Vol 3, Issue 6
Abstract
Malachite dye is among the millions of dyes used in every aspect of our daily life. The adsorption kinetic of the pollutant (dye) from adsobate using palm kernel shell (Elaeis Guineasis) as the biomass was studied. From the several experimental parameters measured, the optimum adsorption occurred at 20 minutes giving 92.3%. Adsorption also decreased from 92.49% to 87.9% with increase in absorbent dosage giving the optimum dosage of 2g. Also increase in temperature decreased the adsorption from 95.6% to 92.7% having it optimum temperature to be 30oC. Increase in dye ion concentration from 10-50mg/L also increased adsorption from 79.3% to 93.0%. There was a decrease in the percentage of dye removed for all the parameters investigated except for dye ion concentration. The value of SF for Langmuir model is 0.232 and R2 value is 0.6326 while for Freundlich model, the value of 1/n is 2.8092 and R2 value is 0.9135 which indicate that Langmuir and Freundlich model are both good isotherm models because they have a SF value of < 1 and 1/n value > 1. Pseudo second order model best fit the experimental data than pseudo first order having R2 values of 1 and 0.5613 respectively. This shows that palm kernel shell can be used as an effective biomass for removing waste water from dye.
