Starch‐based adsorbents have demonstrated excellent potential for the removal of various noxious dyes from wastewater. This review critically evaluates the recent progress in applications of starch‐based adsorbents for the removal of dyes from water. The synthesis methods of starch‐based composites and their effects on physicochemical characteristics of produced adsorbents are discussed. The removal of various dyes by starch‐based adsorbents are described in detail, with emphasis on the effect of key parameters, adsorption mechanism and their reusability potential. The key challenges related to the synthesis and applications of starch‐based adsorbents in water purification are highlighted. Based on the research gaps, recommendations for future research are made. The evaluation of starch‐based adsorbents would contribute to the development of sustainable water treatment options in near future.

“…[16] For improving the properties, [17][18][19] of the starch polymer, [20] starch can be mixed with various synthetics, [21,22] and natural polymers [23] such as multilayer structures, [24,25] with aliphatic polyesters, chitosan, blends with natural rubber and composites with fibers. [26,27] The modified properties of biopolymer [28][29][30][31][32] can be utilized in different applications such as polymer electrolytes for lithium batteries, [33] electronic applications, [34,35] as a membranes for separation, as a catalysis, lab-on-chip technologies, stimuli-responsive shape memory polymer, [36] biomedical application, [37,38] orthopedic surgery, [39] tissue engineering, and 3D printed scaffolds for bone tissue regeneration. [40] The biopolymer based design can be inspired from mussel-inspired crosslinking, [41] microporous shape memory polymers, [42] biomaterials science and engineering.…”

Swelling and Shrinking Behavior of Modified Starch Biopolymer with Iron Oxide

et al. 2020

View full text Add to dashboard Cite

Rapid consumption of petroleum‐based polymers has resulted in the growth of global production but such polymers have a limited source and slow degradation rate. Biopolymers are an alternative sustainable material that can be synthesized using natural sources. In this study, a starch‐based biopolymer composite is synthesized using various concentrations of iron oxide as a binder. A decreased absorption of water is found with an increase in binder concentration. The swelling (absorption) and shrinking (desorption) behaviors of biopolymers are studied as a function of pH, sodium chloride salt, and alcohol (methanol and ethanol). The diffusion model is used to study the absorption and desorption behavior of the biopolymer. Electron microscopy and elemental analysis find iron and oxygen atoms at the composite surface. Fourier transform infrared spectroscopy and X‐ray diffraction confirm that iron oxide is bound with starch. The mechanical hardness of the biocomposites is studied at varied of binder concentrations. This biocomposite can be utilized in packaging, electronics, sensor, and biomedical applications.

“…Depending on the approaches used; functional groups can attach onto the nanotubes' surface to disperse them in the matrix. [18][19][20] In recent years, the use of biosafe and biodegradable adsorbent materials such as poly (vinyl alcohol), chitosan, and starch has received a significant attention due to their outstanding adsorption performance, low cost, wide availability, and the presence of various functional groups. [17] Besides different kinds of modifiers, the surface modification of CNTs with biosafe, biocompatible, biodegradable, and environmentally friendly organic molecules has been reported, showing the improvement of CNTs' spreading in starch and other matrixes.…”

The purpose of this research was to fabricate starch nanocomposites (NC)s using corn starch and MWCNTs-Valine as efficient fillers, and to examine the impact of nanofillers on the starch's properties. At first, Valine was grafted onto the MWCNTs' surfaces through a chemical reaction. Then, the functionalized MWCNTs (0.5, 1, and 2 wt.%) were embedded in the starch by ultrasonic technique. The field emission scanning electron microscopy showed homogeneous distribution of nanofillers in the starch matrix. Moreover, thermogravimetric analysis demonstrated that the starch's thermal stability was improved after addition of MWCNTs. Finally, the adsorption behavior of the prepared NC for the elimination of copper ions from the aqueous solution was investigated.
