“…Towards this end, a large number of approaches have been applied for removal of dyes from wastewater, such as adsorption, membrane-based separation, electro-coagulation, biochemical degradation and oxidative degradation [16][17][18][19][20][21]. Among them, adsorption technology has been widely recognized to be one of the most effective methods due to its high efficiency and ease of handling [22].…”

We designed and synthesized a magnetic metal organic frameworks (MOFs) composite, Cu-MOFs/Fe3O4 as the adsorbent for removal of lead (Pb(II)) and malachite green (MG) in wastewater. This Cu-MOFs/Fe3O4 can be easily prepared by in-situ growth of Cu-MOFs with doping Fe3O4 nanoparticles. The prepared Cu-MOFs/Fe3O4 composite was well characterized by SEM, XRD, and FTIR spectra. The adsorption experiments found that Cu-MOFs/Fe3O4 can serve as adsorbent for removal of Pb(II) and MG simultaneously. The adsorption capacities were found to be 113.67mg/g for MG and 219.00 mg/g for Pb 2+ , respectively, which are significantly higher than reported materials. Adsorption isotherm, kinetics and recyclability of Cu-MOFs/Fe3O4 for removal of Pb(II) and MG were then studied. Adsorption of Pb(II) and MG exhibited Freundlich adsorption isotherm model, with the adsorption kinetics of available second-order kinetic. Physical adsorption for MG and chemical adsorption for Pb(II) were confirmed by Dubinin-Radushkevich (D-R) isothermal adsorption model. The adsorption of Pb(II) and MG in real water samples were then studied. The Fe3O4/Cu-MOFs was found to be recyclable for removal of Pb(II) and MG, can be explored as the potential adsorbent for waste water treatment.

“…This helps to neutralize the charge that the dye molecules carry, which in turn enables effective precipitation. In applications involving the coagulation of blood, biopolymers are the material of choice since, in contrast to traditional coagulants, they do not pose a threat to human health and have a lower impact on the environment [ 176 ].…”

Starch-Based Polymer Materials as Advanced Adsorbents for Sustainable Water Treatment: Current Status, Challenges, and Future Perspectives

et al. 2023

Over the past three decades, chemical and biological water contamination has become a major concern, particularly in the industrialized world. Heavy metals, aromatic compounds, and dyes are among the harmful substances that contribute to water pollution, which jeopardies the human health. For this reason, it is of the utmost importance to locate methods for the cleanup of wastewater that are not genuinely effective. Owing to its non-toxicity, biodegradability, and biocompatibility, starch is a naturally occurring polysaccharide that scientists are looking into as a possible environmentally friendly material for sustainable water remediation. Starch could exhibit significant adsorption capabilities towards pollutants with the substitution of amide, amino, carboxyl, and other functional groups for hydroxyl groups. Starch derivatives may effectively remove contaminants such as oil, organic solvents, pesticides, heavy metals, dyes, and pharmaceutical pollutants by employing adsorption techniques at a rate greater than 90%. The maximal adsorption capacities of starch-based adsorbents for oil and organic solvents, pesticides, heavy metal ions, dyes, and pharmaceuticals are 13,000, 66, 2000, 25,000, and 782 mg/g, respectively. Although starch-based adsorbents have demonstrated a promising future for environmental wastewater treatment, additional research is required to optimize the technique before the starch-based adsorbent can be used in large-scale in situ wastewater treatment.

Review on Spinning of Biopolymer Fibers from Starch

et al. 2021

Increasing interest in bio-based polymers and fibers has led to the development of several alternatives to conventional plastics and fibers made of these materials. Biopolymer fibers can be made from renewable, environmentally friendly resources and can be fully biodegradable. Biogenic resources with a high content of carbohydrates such as starch-containing plants have huge potentials to substitute conventional synthetic plastics in a number of applications. Much literature is available on the production and modification of starch-based fibers and blends of starch with other polymers. Chemistry and structure–property relationships of starch show that it can be used as an attractive source of raw material which can be exploited for conversion into a number of high-value bio-based products. In this review, possible spinning techniques for the development of virgin starch or starch/polymer blend fibers and their products are discussed. Beneficiation of starch for the development of bio-based fibers can result in the sustainable replacement of oil-based high-value materials with cost-effective, environmentally friendly, and abundant products.
