| Summary: | Aim: This study was mainly highlighted on a combination of fungal biomass onto MWCNTs in order to enhance the
positive integration of impurities removal in aqueous solution.
Methodology and results: The immobilization of fungal biomass and MWCNTs was done in a batch liquid medium with
several factors such as agitation speed, dose of MWCNTs, pH and inoculum dosage that were conducted with one
factor at one time (OFAT) method. Basically, to verify the functional group of MWCNTs, Aspergillus niger biomass and
immobilized A. niger biomass, the FTIR was applied and FESEM was done to demonstrate and compare the image of
the immobilized A. niger biomass with MWCNTs and fungal biomass alone. The finding showed the best agitation
speed, dose of MWCNTs, pH and inoculum dosage were 150 rpm, 0.5 g, 5-6 and 2% respectively. FTIR indicates the
presents of the functional groups like –OH (3270 cm
-1
), C-O (1619 cm
-1
) and –CH (2915 cm
-1
) while FESEM illustrates
the images of the wrapped MWCNTs on A. niger biomass.
Conclusion, significance and impact of study: The conventional technique of adsorption of fungal biomass alone not
showing a favorable removal of impurities. Thus, the immobilization of fungal biomass (A. niger) with multi-walled carbon
nanotubes (MWCNTs) was a good combination since both have potential functional group to accumulate to each other
and has a tendency to remove effectively and efficiently the impurities in aqueous solution. |
