Adsorption of Methylene Blue by Banana Stem Adsorbent in a Continuous Fixed Bed Column Study

Abstract

Methylene Blue is a cationic dye that releases aromatic amines in many textile industries and can cause potential harm to human health. Agricultural waste has been explored for their adsorption abilities towards Methylene Blue dye from textile wastewater. This study described the performance of fixed-bed column using banana stem as filter media under the effect of various bed height (10, 30, 50 cm) and initial concentration of Methylene Blue ( 0.02 and 0.03 mg/L) to assess the breakthrough curve. From the fixed-bed column study, the column with initial Methylene Blue concentration of 0.02 mg/L and bed height of 50cm performed well in removing Methylene Blue from the synthetic Methylene Blue solution. The breakthrough time and exhaustion time were 953.57 minutes and 4560 minutes, respectively. As a conclusion, banana stem filter media is an effective alternative in removing Methylene Blue from textile wastewater.

Methylene Blue Dye Removal Utilizing Green Waste-Banana Stem Based Biomass

“…As the number and types of textile products increase, the industry uses a variety of dyes containing different chemicals, making the wastewater treatment process more complex. In aquatic organisms, dyes have mutagenic, teratogenic and carcinogenic effects [7]. It is therefore important to limit or fully treat the dye pollution before discharging it into the water bodies.…”

“…It is one of the synthetic pigments that disperses in water to create a dark blue shade. Methylene blue is much problematic due toitsconsequenceofaccumulation inside cytoplasmand cell [7]. High visibility water that contains small amounts of methylene blue affects aquatic life by interfering with the transmission of oxygen and light.…”

Synthesis of Nanoporous Biochar from Rice Husk for Adsorption of Methylene Blue

“…Some of the dyestufs themselves, their degradation products, and the toxic substances contained in the dye efuent have a "triple-causing" efect and pose a serious risk to human health. Under certain conditions, azo dyes can reduce certain aromatic amines, which are carcinogenic to humans or animals [7].…”

Characterization of Date Seed Powder Derived Porous Graphene Oxide and Its Application as an Environmental Functional Material to Remove Dye from Aqueous Solutions

“…Specifically, the application of activated carbon [16] has long been the norm [17,18]. Many adsorbents have been developed in recent years [9] for the removal of dyes, such as layered double hydroxides [19], metal oxides, clay [20][21][22], natural goethite [23], and sediments [24,25].…”
