Microwave-Assisted Preparation of Magnetic Citric Acid-Sugarcane Bagasse for Removal of Textile Dyes

Abstract

Wastewater from industries has been a serious issue that both manufactures and authorities raise concerns since it brings tremendous demerits to the surrounding environment and human well-being. Therefore, an appropriate treatment method should be applied before being discharged into the environment. In this paper, sugarcane bagasse was modified with citric acid and then used to load the suspension of Fe3O4 nanoparticles to form a nanocomposite of magnetic citric acid-modified sugarcane bagasse. The properties of prepared materials were investigated by a variety of modern methods such as X-ray diffraction (XRD), Fourier transforms infrared spectroscopy (FT-IR), Scanning electron microscopy (SEM), Transmission electron microscopy (TEM) and a Vibrating sample magnetometer (VSM). The adsorptive capacity of prepared materials was investigated with methylene blue as the typical adsorbate. The decolonization effectiveness was increased with increasing contact time and declined with rising initial dye concentration. The higher removal efficiency was observed for the basic medium in comparison with the acidic medium. Additionally, the results showed that more than 12.42 mg/g (98%) of cationic yellow 51, and basic red 46 dyes were removed after 30 min.

Facile microwave-assisted preparation of Fe3O4 nanoparticles supported on carbonized cellulose nanocrystals derived from sugarcane bagasse

“…IONPS have been investigated for several applications, including catalysis (Jung et al 2007) and adsorption of dyes (Anh et al 2020) as well as heavy metals (Bai et al 2021) from wastewater. In these applications, the nano-size of the spherical IONPs enabled a larger surface area for better reactions or adsorption.…”

“…Various sugarcane bagasse applications have been reported over the years. For instance, adsorption studies using sugarcane bagasse-derived materials have been conducted to remove heavy metals (Pehlivan et al 2013;Wang et al 2017;Bai et al 2021), tetracycline (Rattanachueskul et al 2017) and methylene blue (Anh et al 2020) from aqueous solutions, while other reports had prepared nanomaterials (Alves et al 2012) and nanocatalysts for transesterification of waste cooking oil to bio-diesel (Nazir et al 2022). Graphene oxide has also been produced from sugarcane bagasse-derived material (Somanathan et al 2015).…”

“…Because excessive exposure to microwave radiation is hazardous, safety procedures must be created before deploying microwave energy on a wide scale [185][186][187][188].…”

Adsorption of Anionic and Cationic Dyes in Batik Wastewater Using Biomass Adsorbents: Literature Review

“…[21] made adsorbents from cassava peel biomass, but adsorbents produced by Astuti et al [31] In addition to the modification methods described above, there is another modification method, namely the manufacture of nanoparticles or nanocomposites. For example, Anh et al [35] synthesized nanocomposites using Fe3O4 and sugarcane bagasse. The produced adsorbent has a higher adsorption efficiency than natural bagasse without modification of 98%, while natural bagasse was 66%.…”

“…This group will then bind to the sulfonate group (SO3 -) in the dye. Anh et al [35] studied the effect of pH on the adsorption process of cationic dye methylene blue with bagasse adsorbent. The variations of pH used were from 3 to 9.…”
