“…No bacterial regrowth was observed in treated water stored in the light/dark for 7 days. 104 DPC was also explored for photo-disinfection of the fluoroquinolone-resistant genes parE and gyrB, and it was shown to significantly reduce the amount of these genes present. DPC proved to be a stable photocatalyst as it was tested over 7 months and it gave optimal results, showing it to have the potential for commercialization.…”

The advent of civilization, coupled with growing industrialization in many countries, is placing more demand on the available water sources. At the same time, the daily surge in wastes generated by man's anthropogenic activities has led to microbial, organic and inorganic contamination of water sources. Based on available evidence, significant research efforts are being made into the use of low‐cost agricultural materials such as Carica papaya seed (CPS) in the removal of these contaminants from water sources in a bid to provide clean water. In the present review, the organic, inorganic and microbial contaminants in waters were elucidated. Furthermore, the chemical composition of the CPS was illustrated. The adsorption capacity and efficiency of CPS and their composites in the remediation of the selected contaminants were discussed while identifying the various factors affecting the adsorption efficiency. Finally, the reusability of this agricultural material was discussed. Solution pH was identified as a major factor influencing the sorption process. The high removal efficiency reported in the studies that adopted CPS showed its vast potential in the elimination of contaminants from water sources. Also, the regenerative potential of the adsorbent over several cycles indicated its long‐term use. The economic feasibility and environmental sustainability afforded by using CPS chart a path for further investigation into the use of other low‐cost agricultural materials in the elimination of environmental contaminants. © 2023 Society of Chemical Industry (SCI).

“…One of the advantages of using clay materials in removal processes is that it is an economical material with a high capacity to remove organic and inorganic pollutants [90]. One of its important characteristics, in addition to being one of the more abundant adsorbents in nature, is that it has a high ion exchange capacity, high specific surface area, and good colloidal dispersion, making these materials good for the treatment of wastewater containing organic and inorganic compounds, among others [91][92][93].…”

In recent decades the presence of pollutants has grown considerably around the world, along with the scarcity of fresh water. One of the environmental problems that has intensified lately is the presence of antibiotic resistant strains and the appearance of resistant genes due to the misuse and high worldwide consumption of this type of pharmaceutical products. Therefore, the number of investigations has been intensified to address these great problems that can affect public health and cause great economic losses around the world. For this reason, in this review, different antibiotics removal techniques in water have been compiled and analyzed critically.

“…In recent years, natural layered clay minerals have been widely used as catalyst carriers because of their excellent carrier effects (cocatalysis, codispersion, and cosorption). − Nanoclays have obtained extensive attention in the defect regulation of nanomaterials due to their unique structure and abundant surface hydroxyl groups (silicon and/or aluminum hydroxyl groups) . Our previous work found that Al–OH on the kaolinite surface plays a pivotal role in regulating the amount of oxygen vacancy and Co 2+ on the Co 3 O 4 surface; the hydroxyl group of kaolinite can react with intermediate groups to form defective g-C 3 N 4 and the modulation of defects can be achieved by changing the number of hydroxyl groups .…”

Mineral-Enhanced Manganese Ferrite with Multiple Enzyme-Mimicking Activities for Visual Detection of Disease Markers

Local geometric configurations of metal cations in inorganic enzyme mimics determine their catalytic behaviors, while their optimization remains challenging. Herein, kaolinite, a naturally layered clay mineral, achieves the optimization of cationic geometric configuration in manganese ferrite. We demonstrate that the exfoliated kaolinite induces the formation of defective manganese ferrite and makes more iron cations fill into the octahedral sites, significantly enhancing the multiple enzyme-mimicking activities. The steady-state kinetic assay results show that the catalytic constant of composites toward 3,3′,5,5′-tetramethylbenzidine (TMB) and H2O2 are more than 7.4- and 5.7-fold higher than manganese ferrite, respectively. Furthermore, density functional theory (DFT) calculations reveal that the outstanding enzyme-mimicking activity of composites is attributed to the optimized iron cation geometry configuration, which has a higher affinity and activation ability toward H2O2 and lowers the energy barrier of key intermediate formation. As a proof of concept, the novel structure with multiple enzyme-mimicking activities amplifies the colorimetric signal, realizing the ultrasensitive visual detection of disease marker acid phosphatase (ACP), with a detection limit of 0.25 mU/mL. Our findings provide a novel strategy for the rational design of enzyme mimics and an in-depth investigation of their enzyme-mimicking properties.
