“…Here, the accumulated 2,4-DP ions depend on the availability of anion in the aqueous solutions following the order of PO 4 3− > CO 3 2− > Cl − with percentages of 83, 65, and 30%, respectively. Phosphate ions with the highest percentage confirm that a higher density charge affects a higher amount of PO 4 3− anion to be exchanged with 2,4-DP anion [18]. Therefore, PO 4 3− anions are interleaved into the Ca-Al LDH interlayer during the controlled release process, which simultaneously releases the 2,4-DP ions out from the interlayer into the aqueous solution.…”

The commonly used herbicide in agriculture, namely 2,4-dichlorophenoxypropanoic acid (2,4-DP), is an anionic herbicide used to interleave into the interlayer of calcium-aluminum layered double hydroxide (Ca-Al LDH) employing co-precipitation method to form a new nanohybrid labeled as CAL-2,4DP. The LDH compound serves as a host in supporting the herbicide’s controlled release formulation. The effective interleave was investigated by employing a powder X-Ray Diffraction (XRD) pattern at 0.025 M nanocomposite, which revealed that the basal spacing has increased from 8.0 Å to 23.8 Å. The ATR-FTIR spectra further supported the interleaving, where the nitrate peak (NO−) diminished, and the carboxylate ion (COO−) band appeared at 1653 cm−1. The percentage loading of CAL-2,4DP was 71.26%, calculated from the carbon content in the sample. The BET analysis shows that CAL-2,4DP was a mesoporous material relying on nitrogen-desorption isotherms. The release of 2,4-DP ions into the aqueous solutions followed the order of PO43− > CO32− > Cl− with a percentage of 83, 65, and 30%, respectively. This work indicates the successful interleaving process of the 2,4-DP anion and the potential of CAL-2,4DP as an eco-friendly agrochemical that can be beneficial for farmers in minimizing herbicide usage to the environment.

“…5 shows the FTIR-ATR spectra of the Ca-Al LDH host and its guest. Because of the O-H stretching and bending vibration of the hydroxyl groups in the interlayer water molecules, bands exist at 3460 cm −1 and 1631 cm −1 at Ca-Al LDH [18]. Note that a sharp band at 1325 cm −1 associates with the nitrate stretching vibration.…”

“…The vital transitions for GO were (n→σ*) and (π→π*). The absorption was observed at 245 nm due to the aromatic C=C bond for transition (n→σ*) [19]. Furthermore, the absorption peak at 300 nm was stood for C=O bond transition (π→π*).…”

In this present work, herbicide named 2-methyl-4-chlorophenoxy acetic acid (MCPA) was intercalated into the graphite oxide through ion-exchange method to produce an MCPA-GO nanocomposite as an herbicide delivery system. The formation of MCPA-GO nanocomposite was confirmed by using PXRD, Fourier Transform Infrared Spectroscopy (FTIR), Thermal Gravimetric Analysis (TGA), UV-Visible Spectroscopy and Accelerated Surface Area Surface (ASAP). As for PXRD pattern, there was increasing in the basal spacing of the nanocomposite from the graphite oxide which by 9.3 to 9.7 Å indicated that MCPA has successfully inserted into the interlayers of the graphite oxide. Meanwhile, the FTIR spectrum showed the appearance of a new peak in MCPA-GO nanocomposite at 1308 cm -1 represents the functional group of carboxylate (COO -). This peak is very necessary for the confirmation of the anionic form of MCPA inserted into the interlayers of graphite oxide. The controlled release property was also done for further investigation by using various aqueous media to determine the percentage release of MCPA from the nanocomposite. The percentage of herbicide release in Na3PO3 solution was higher than in Na2CO3 and NaCl solution proved that the release properties exhibit the potential application of graphite oxide as effective nanocarrier of herbicides. MCPA-GO nanocomposite suggested being most promising herbicide since it can lower the toxicity of precursor MCPA, high biocompatibility, and more efficient in herbicide delivery system.

“…Subsequently, hydrothermal treatment was employed to increase the product's crystallinity. To clarify, there are few studies on intercalating MCPA into ZLH that have been employed [25,26], but there haven't been any published studies investigating the effect of protein and amino acid content of plant samples treated by this nanoherbicide yet. Due to this reason, in this present study, the protein and amino acid composition in leaves of bean sprout samples was reported following the application of herbicide with aimed to broaden the limited scientific knowledge by supporting the impact of nanoherbicides on plant gene expression.…”

2-methyl-4-chlorophenoxyacetic acid (MCPA) was successfully intercalated into zinc layered hydroxide (ZLH) by anion exchange technique followed by hydrothermal treatment, resulting in the formation of nanoherbicide, zinc-layered hydroxide-2-methyl-4-chlorophenoxyacetic acid (ZMCPA). Fourier-transform infrared spectroscopy (FTIR) and Powder X-ray diffraction (PXRD) was used to confirm the intercalation of herbicide into ZLH, while Ultraviolet-visible spectroscopy (UV-vis) was employed to assess the plant’s protein content and amino acid composition before and after 1 h treatment with ZnO, MCPA and ZMCPA via the foliar technique and direct soil application. The basal spacing of ZMCPA in this study is 21.6 Å at 4.0815°, revealing the triumphant incorporation of MCPA into the ZLH host. The zinc oxide (ZnO) fingerprint from 30° to 60° that certainly vanished in the ZMCPA diffractogram indicates that all ZnO has successfully converted to ZLH matrices. The FTIR spectrum of ZMCPA shows the similarity of most MCPA spectra, but with the COO– peaks at 1610 and 1700 cm–1 replacing the intense C=O band at 1742.21 cm–1, implying that the herbicide has assimilated into the host. The protein level of the plant treated with ZMCPA was discovered to be more significant, which signifies that ZLH has effectively acted as a herbicide carrier. This study has depicted the potential of ZMCPA as a more unassailable agrochemical agent in increasing crop productivity while minimizing environmental consequences.
