“…[81] Fe 0 , Ag, and Fe 3 O 4 are among the most nanoparticles by which starch has been integrated and used for treatment of aqueous solutions containing Cr(VI), Hg(II), nitrate, arsenic, etc. [36,58,62] Apart from increasing adsorption capacity, coupling with nano-particles has shown the advantages of recyclability and recoverability. Modification of starch with crosslinking agent can improve its catalytic activity and enhance the adsorption capacity.…”

Currently, the application of natural materials is a good alternative to prevent secondary damage to humans and the environment. Therefore, in recent years, much attention has been paid to the use of these degradable and environmentally friendly materials to reduce toxicity and treatment costs. As a natural material, starch offers advantages of low cost, flexible modification, abundant presence of hydroxyl functional groups, and eco‐friendly. These configurations make it to a suitable material for remediation purposes, as it has received a great attention for removal of pollutants from water and wastewater, including but not limited to the heavy metals, pharmaceutical, dyes, and even inorganic contaminants. This work, therefore, aims to systematically evaluate starch‐based materials applications in remediation of water and wastewater media using the appropriate search terms from international databases including PubMed, Science Direct and Google Scholar, and through PRISMA checklist. For this, the publications from 1973 to 2021 are searched. In the initial search, 980 articles are found of which 49 articles are included in the study. Then, the performance of the starch‐based materials for every single study as the pollutant(s) involved is summarized and discussed. The advantages and disadvantages of such application are extracted and a perspective is presented accordingly. This comprehensive review shows that the starch‐based derivatives’ can be potential options in water and wastewater treatment purposes, especially those modified. However, some limitations should be overcoming before scaling of the results.

“…The starch can be easily restored through weak acidic washing, and the success of metal removal depends on avoiding highly acidic metal solutions. Increasing the levels of carboxymethylation and cross-linking can enhance the metal scavenging activity of starch, making it suitable for industrial applications [ 62 , 64 , 155 , 156 , 157 ].…”

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

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.
