“…2 ) showed the characteristic functional groups of the AM and CMC units. For biochar, the characteristic peak at 3392 cm −1 was due to the bound water and nitrogen hydrogen band and illustrates that some amino groups and hydroxyl groups were present on the surface of the biochar 47 , 48 . The band at 1600 cm −1 corresponded to the stretching vibration C=C of aromatic groups in biochar 49 , and the peak at 1412 cm −1 referred to C=O.…”

A novel composite hydrogel (AM/CMC/B) synthesized from peanut shell biochar effectively adsorbs heavy metal Cd in water and reduces its toxicity to tobacco seedlings. The hydrogel, prepared via hydrothermal polymerization using acrylamide (AM), carboxymethyl cellulose (CMC), and peanut shell biochar (B), exhibited a maximum adsorption capacity of 164.83 mg g−1 for Cd2+ and followed a pseudo-second-order kinetic model. In pot experiments, the application of exogenous AM/CMC/B mitigated the inhibitory effects of Cd-contaminated soil on tobacco seedling growth. Addition of 10 mg kg−1 Cd resulted in improved phenotype, root system development, enhanced photosynthetic capacity, stomatal conductance (Gs), stomatal number, and increased antioxidant activity while reducing MDA content and leaf cell death. These findings highlight the potential of AM/CMC/B as an environmentally friendly adsorbent for Cd removal from water and for reducing Cd stress toxicity in tobacco and other plants.

“…Taken together, as illustrated in Figure 11, OPB with higher preparation temperatures, the main contributions in adsorption process were electrostatic attraction and pore filling, as well as functional group action, hydrogen bond formation, and ion exchange [17, 48]. The isothermal, kinetic, and thermodynamic analyses concluded that the driving force of La(III) and Y(III) in solution enhanced at higher ion concentrations and higher temperatures, which accelerated their diffusion and purposeful approach to the OPB adsorbents, thereby promoting the feasibility and spontaneity of adsorption.…”

In this work, orange peel (OP) was used as raw material to produce biochar. The effect of oxygen-limited carbonization temperature (200, 400, and 600°C) on the physicochemical properties and adsorption behavior of orange peel biochar (OPB) toward La(III) and Y(III) in aqueous media was studied. The prepared OPB samples were characterized by SEM, FTIR, and XRD. The experimental results exhibited effective removal of La(III) and Y(III) from aqueous solution by OPB. The carbonization promoted the pore development, and the adsorption process occurred rapidly. The main chemisorption of La(III) and Y(III) on OPB was analyzed by the Langmuir and pseudo-second-order kinetic model, and the participations of electrostatic attraction, exchange, and hydroxyl and carboxyl complexation in OPB were confirmed. The Langmuir maximum capacity of 55.57 mg/g and 31.49 mg/g was obtained at the optimum pH range of 4~6 and the OPB dosage of 1 g/L and 2 g/L for La(III) and Y(III). The efficient orange peel biochar with high adsorption performance can be obtained by considering suitable carbonization temperature.

“…[17,18] This carbohydrate which is formed by photosynthesis in plants and annually produced by ≈70 × 10 6 tons, consists of a mixture of two polymers of amylose as well as amylopectin. [19,20] 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, [21] including but not limited to the heavy metals such as cadmium, [22] lead, [23] arsenic, [24] pharmaceutical contaminants [25,26] especially antibiotics, [27] dyes, [28,29] and even inorganic contaminants of phosphate, [30] nitrate, and fluoride. [31] Although starch has been mainly studied for such application in the different ways (either as the pristine or modified form), its effect on pollutants removal from aqueous solutions has not been researched thoroughly to the best of the authors' knowledge.…”

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.
