“…Nanoceramics removed approximately 72% of paraquat within 10 h. The result echoes paraquat adsorption onto a ceramic surface through electrostatic interaction. The efficiency of clay minerals, such as kaolinite, zeolite, and montmorillonite, as an absorbent in removing paraquat from an aqueous solution has been reported in many studies [ 15 , 16 , 17 , 18 , 19 ].…”

The biodegradation of paraquat was investigated using immobilized microbial cells on nanoceramics fabricated from nanoscale kaolinite. Pseudomonas putida and Bacillus subtilis, which degrade paraquat, were immobilized separately on nanoceramics (respectively called ICnc−P and ICnc−B). The attachment of bacteria to nanoceramics resulted from electrostatic force interactions, hydrogen bonding, and covalent bonding (between the cells and the support materials). The initial 10 mg L−1 concentration of paraquat in water was removed by the adsorption process using nanoceramics at 68% and ceramics at 52%, respectively. The immobilized cells on the nanoceramics were able to remove approximately 92% of the paraquat within 10 h, whereas the free cells could only remove 4%. When the paraquat was removed, the cell−immobilized nanoceramics exhibited a significant decrease in dissolved organic nitrogen (DON). ICnc−B was responsible for 34% of DON biodegradation, while ICnc−P was responsible for 22%. Ammonia was identified as the end product of ammonification resulting from paraquat mineralization.

“…To remove paraquat from polluted water, clay minerals such as montmorillonite, nontronite, and kaolinite are among potent adsorbents [ 15 , 16 , 17 , 18 , 19 ]. Recently, many researchers have gained attention from clay−based nanomaterials with specific chemical and biological properties.…”

“…Additionally, compared to noncarbon materials, MB-01-850 exhibited higher adsorption efficiency than several inorganic materials. For example, the bentonite/mesoporous silica compound [77], humic acid-coated goethite [59], kaolin [78], and zeolite Y [82] showed Q 0 values of 11.75 mg/g, 4.40 mg/g, 5.45 mg/g, and 26.38 mg/g, respectively. In summary, the adsorbents used for paraquat removal demonstrated removal efficiencies ranging from 4.40 mg/g to 257 mg/g.…”

Due to the widespread production of maize, the waste created by this crop has become a serious concern. This study applied the concept of waste circulation to the production of magnetic biochar from corn husk waste to remediate paraquat-contaminated water. Magnetic biochar (MB) was produced by impregnating maize husks with iron and carbonizing the residue in a nitrogen environment. Carbonized MB at the temperature of 850°C (MB-01-850) exhibited a combination of microporous and mesoporous structures ( V meso = 0.30 c m 3 / g , V micro = 0.12 c m 3 / g ), while biochar created only a microporous structure ( V micro = 0.11 c m 3 / g ). According to the findings, Fe(NO3)3 significantly affected the increase in mesopore formation after carbonization. In addition, biochar exhibits excellent magnetic responsiveness. MB-01-850 reached equilibrium within approximately 20 min in synthetic water. Batch adsorption studies showed that MB-01-850 had maximum adsorption capacities ( Q 0 ) of 34.97 mg/g and 31.63 mg/g for synthetic and natural water, respectively. The unmodified biochar (without mesopores) had a Q 0 of 4.08 mg/g. This indicates that the presence of mesopores improves the effectiveness of paraquat adsorption. Additionally, the adsorption performance of magnetic biochar exhibited no statistically significant variance when tested under natural water conditions. Furthermore, magnetic biochar demonstrates impressive regeneration capacity, allowing it to be regenerated almost entirely for a minimum of four cycles using a sodium hydroxide (NaOH) solution with a concentration equal to or greater than 0.5 M.

“…The zeolite Y is used as an adsorbent in extraction process for the determination of pesticide residues in water and agricultural products. It is also used as a sorbent for pesticide, herbicide, and hydrocarbon (such as paraquat, linuron, and ethylene) [12,13]. According to the structure of zeolite Y, which contains large channels and negative oxygen sites, it is interesting that the zeolite Y and 2,4-dichlorophenolixyacetic acid www.scienceasia.org might interact with each other by hydrogen bond and intermolecular forces.…”

The removal of 2,4-dichlorophenoxyacetic acid (2,4-D) by zeolites (ZY, ZY-10, and ZY-200 with Si/Al ratios of 6.07, 14.68, and 207.25, respectively) and modified zeolites with hexadecyltrimethyl ammonuium (HDTMA) were investigated. The influence of HDTMA concentration, modification methodology, and 2,4-D initial concentration were evaluated for 24 h at room temperature (30°C). The results showed that the best adsorption capacity was obtained from 15 mM HDTMA using a dropwise method and 10 mg/l 2,4-D solution. The best adsorption capacities of the unmodified and modified zeolites were 20.
