ADSORPTION BEHAVIOUR OF P-NITROPHENOL IN AQUEOUS MEDIUM ON NON-TREATED SABA AND LADY FINGER BANANA PEELS
The adsorption behavior of p-nitrophenol (pNP) was studied on two types of banana peels (Saba banana and Lady Finger banana) in aqueous medium. The results showed that, the optimum mass of banana peels to adsorb p-NP were 0.1 g (Saba banana) and 0.02 g (Lady Finger banana). The adsorption exhibits h...

| Summary: | The adsorption behavior of p-nitrophenol (pNP) was studied on two types of banana peels (Saba banana and Lady Finger banana) in aqueous medium. The results showed that, the optimum mass of banana peels to adsorb p-NP were 0.1 g (Saba banana) and 0.02 g (Lady Finger banana). The adsorption exhibits higher uptake of p-NP onto Saba and Lady Finger banana peels in pH 7. The adsorption of p-NP onto both type of banana peels achieved equilibrium at 480 minutes contact time. The adsorptions of p-NP onto banana peel well fitted with Freundlich isotherm (R2 > 0.9). The FESEM micrographs showed that both peels have an irregular shape and porous texture which contributed to the adsorption behavior of p-NP in aqueous medium onto banana peels. © Malaysian Journal of Microscopy (2021). |
