A Green and Facile Approach for Synthesis of Starch-Pectin Magnetite Nanoparticles and Application by Removal of Methylene Blue from Textile Effluent

Abstract

Pectin-starch magnetite hybrid nanoparticles were fabricated, characterized, and evaluated as potential absorbents for methylene blue dye based on recycling water from the textile industry. The nanocomposite adsorbent was synthesized with the iron salt coprecipitation method, and the precipitates obtained were sponge-like. The effects of a pectin : starch ratio in the absorbent and the amount of methylene blue adsorbed were investigated. The nanocomposites obtained were characterized using a Fourier-transform infrared spectroscopy (FTIR), before and after methylene blue adsorption. Fourier-transform infrared spectroscopy (FTIR) spectra provided the evidence that the starch-pectin iron oxide hybrid nanoparticles were successfully synthesized. It also indicated that the hybrid nanoparticles actually absorbed the methylene blue dye from the effluent. PXRD results showed that the synthesized hybrid composite adopted the spinel microstructure of Fe3O4 though the crystallinity of the composite decreased with an increase in the pectin : starch ratio. Furthermore, calculations based on PXRD showed that the synthesized powders were nanoparticles. The amount of adsorbed dye by hybrid adsorbent increased with an increase in the starch : pectin ratio, and the increase was better observed at a low polymer concentration of 18%. The amount of adsorbed dye by hybrid adsorbent was high at high pH and low at low pH value which attested to the ion exchange and electrostatic force mechanism during the adsorption process. Finally, the capacity of the absorbent decreased with an increase in temperature.

Structure and Applications of Pectin in Food, Biomedical, and Pharmaceutical Industry: A Review

“…Nsom et al have developed hybrid pectin and starch nanoparticles for use as absorbents for methylene blue dye based on water recycling in the textile industry. According to the results, the nanoparticles have demonstrated efficiency and benefits such as ease of synthesis and recovery, absence of secondary pollutants, cost-benefit, and environmental compatibility [132]. Raghav et al investigated the application of biomaterial scaffolds based on pectin and alginate inside trimetallic oxide to absorb water fluoride.…”

“…Wastewater remediation-adsorption of different heavy metals, including As 3+ , Zn 2+ , and Co 2+ and antibacterial effect [38] MWCNT-starch-iron oxide Adsorbent for removing methyl orange (MO) and methylene blue (MB) from aqueous solutions [58] Table 1.…”

“…Biodegradable polymers, starch/cellulose nanowhiskers hydrogel composite, showed outstanding adsorption capacity to be employed in the remediation of methylene blue contaminated wastewaters [63]. Pectin-starch magnetite hybrid nanoparticles could be potential adsorbents for methylene blue dye with higher adsorption efficiency at a low polymer concentration and starch-pectin ratio and can be used to recycle water from the textile industry [58].…”
