Removal of Eosin dye from simulated media onto lemon peel-based low cost biosorbent

Synthetic dyes from different sources (wastewater and effluents) can be harmful to the environment even at minor quantity. Low cost natural biosorbent have been proved beneficial for water treatment and have excellent capability for the elimination of certain dyes from aqueous media. The present study purposed to utilize lemon peel as a natural sorbent for eosin dye in an aqueous media. The biosorbent were analyzed utilizing fourier transform infrared spectroscopy, scanning electron microscope (SEM), energy-dispersive X-ray analysis (EDX) and surface area ana-lyzer (BET). The batch adsorption approach was carried out to optimize the basic parameters affecting the sorption phenomena. Anionic dye, eosin, was removed by adsorption utilizing lemon peel, as an biosorbent and such adsorption are affected by different physical factors i.e adsorbent dose, contact time, temperature etc. Freundlich and Langmuir's adsorption isotherm models are used to verify the results. The monolayer adsorption capacity was 8.240 mg/g at 30 degrees C that is cal-culated from Langmuir isotherm. The adsorption process is exothermic, shown by calculations ther-modynamic parameters. Kinetics studies have represented that the adsorption process could be better explained by pseudo-second-order kinetics. All the parameters of biosorbent were compared with each other and proved that lemon peel, which is readily available, economic biosorbent, for the

Automated summary

In this study, lemon peel was utilized as a natural sorbent for the removal of eosin dye from aqueous media. The biosorbent was characterized and analyzed, and the adsorption process was optimized. The results showed that lemon peel is an effective and affordable biosorbent for the removal of eosin dye.
