Pesticides are useful in increasing the quantity and quality of agricultural products. However, over-application or misuse would accumulate their residues in the environments, which might pose threats to non-target organisms and humans. Therefore, this study investigated the sorption of herbicide, pendimethalin (PD) onto titanium dioxide nanoparticles (TiO2 NPs) and single-walled carbon nanotubes (SWCNTs) surfaces in aqueous solutions. Several experiments were conducted to study the contact time of the nanoparticles with different concentrations of PD under laboratory conditions. The experiments were done at 25 ºC and pH values 7.0. Sorption results were then fitted using Langmuir and Freundlich isotherm models. Quantities of 0.5 to 2.5 µg/ml of TiO2 NPs and 50.0 µg/ml of SWCNTs exhibited 100.0% and 99.8% removal of PD, respectively. Small amounts of PD (0.5-2.5 µg/ml) were completely removed (100%) by TiO2NPs and SWCNTs particles. Isotherms displayed adsorption capacities of 1.850 and 2.304 µg/g for TiO2NPs and SWCNTs, respectively, which highlight the elevated potential of cleaning the environment from pendimethalin residues.

We elaborate the synthesis and remarkable photocatalytic efficiency of a series of heterojunction nanocomposites with a cauliflower-like architecture composed of copper oxide (CuO) and single-walled carbon nanotubes (SWCNTs). The photocatalysts with such a peculiar design were constructed via facile recrystallization followed by calcination and were symbolized as CuO-SWCNT-1, CuO-SWCNT-2, and CuO-SWCNT-3, representing the components and calcination time in hours. The photocatalytic efficiency of the synthesized nanocomposite samples were investigated by evaluating the decomposition of methylene blue (MB) solution under natural sunlight exposure. All of the as-synthesized photocatalysts were substantially effectual for the photo-deterioration of MB solution. Moreover, CuO-SWCNT-3 revealed the top photocatalytic capability with 96% decomposition of MB solution in 2 h while being exposed to visible light. Pristine CuO nanocrystals and the SWCNTs were employed as controls, whereas the photocatalytic performance of the hetero-composites was significantly better than that of pure CuO as well as SWCNTs. The recyclability of the photocatalysts was also explored, and the results asserted that the samples could be reused for five cycles without being altered notably in photocatalytic performance or morphology.
