Abstract
The adsorption method is a highly effective
technique for adsorbing methylene blue from dye waste. Adsorbents from natural
materials have a high absorption capacity, such as banana peel waste, which
contains very fine fibers with a hemicellulose (6-8%), cellulose (60-65%), and
lignin (5-10%). The effectiveness of adsorbent from Kepok banana peel for
methylene blue dye was studied in this research. The parameters tested include
the characterization of cellulose and nanocellulose using FTIR, SEM and XRD
instruments, determination of the optimum weight, efficiency of cellulose
adsorption, and adsorption capacity of the adsorben. The results show that
cellulose and nanocellulose isolated from banana peel indicate functional
groups in the characteristic absorption regions of cellulose, such as O-H
stretching, C-H, C-O, and C=O functional groups in the FTIR characterization.
SEM analyses confirmed the fibrillar and porous structure of the nanocellulose,
highlighting its suitability for adsorption applications. XRD analysis showed
that the nanocellulose possesses a crystalline structure typical of Cellulose
Type I, with a crystallinity index of ~59.6%. The
optimum weight for cellulose and nanocellulose is 60 mg. The adsorption efficiency of methylene blue ranged from 41.66% -67.38%.
Maximum adsorption capacities of cellulose and nanocellulose were 6.943 mg/g
and 9.673 mg/g respectively. These results indicate that cellulose and
nanocellulose are effective adsorbents for methylene blue under the tested
conditions.
