چکیده
|
This study aimed to investigate how safranin-o can be removed from aqueous solutions by adsorption on pineapple peels. the effect of solution ph, initial dye concentration, contact time and adsorbent dose were studied. the optimum adsorption capacity of 26.08 mg/g was achieved under the experimental condition of ph, temperature and contact time of 6, 293k and 80 min, respectively. also further analysis revealed that 93.24% of safranin-o was significantly removed at 120 mg/l dye concentration in 80 minutes contact time. from the result of the isotherm studies, it was revealed that the equilibrium data is well fitted to freundlich model while the adsorption kinetic data showed that the adsorption process was well described by the pseudo-second order kinetic model. finally, it can be deduced that pineapple peels had a great potential in adsorbing and removal of safranin-o from aqueous solution.
