Abstract
This research has been aimed to experimentally and numerically examine the effect of nanomaterials on pollutant removal in the porous asphalt in urban surface runoff. For this purpose, 19 samples including Titanium dioxide (TiO2), Graphene Oxide (GO), Zinc Oxide (ZnO), and Copper Oxide (CuO) were applied to reduce pollution in surface runoff. Numerical models were simulated using laboratory data in COMSOL software, and the results of these methods were compared with the laboratory results. With a slight difference, the numerical and experimental results indicated the positive effect of adding ZnO and GO and the negative effect of adding CuO and TiO2 to the porous asphalt in reducing the Sulfate (SO₄), Nitrate (NO3), Total Suspended Solids (TSS), and Total Dissolved Solids (TDS) parameters in the polluted water outflow. Also, obtained results showed adding these Nano Particles (NPs) to the porous asphalt at concentrations of 6% and 8% had a beneficial effect and that adding NPs at concentrations of 2% had no effect in reducing the Lead (Pb) parameter dissolved in the polluted water outflow. Overall, the results indicated the positive effect of the ZnO-containing asphalt sample in absorbing and reducing all parameters of pollutants dissolved in the polluted water. The CuO-containing asphalt sample was also discovered to have produced opposite results or have nearly no effect on various parameters, increasing the amounts of pollutants in water outflow. In addition, the asphalt samples containing GO and TiO2 also positively contributed to reducing certain pollution parameters.
期刊介绍：
Physics and Chemistry of the Earth is an international interdisciplinary journal for the rapid publication of collections of refereed communications in separate thematic issues, either stemming from scientific meetings, or, especially compiled for the occasion. There is no restriction on the length of articles published in the journal. Physics and Chemistry of the Earth incorporates the separate Parts A, B and C which existed until the end of 2001.
Please note: the Editors are unable to consider submissions that are not invited or linked to a thematic issue. Please do not submit unsolicited papers.
The journal covers the following subject areas:
-Solid Earth and Geodesy:
(geology, geochemistry, tectonophysics, seismology, volcanology, palaeomagnetism and rock magnetism, electromagnetism and potential fields, marine and environmental geosciences as well as geodesy).
-Hydrology, Oceans and Atmosphere:
(hydrology and water resources research, engineering and management, oceanography and oceanic chemistry, shelf, sea, lake and river sciences, meteorology and atmospheric sciences incl. chemistry as well as climatology and glaciology).
-Solar-Terrestrial and Planetary Science:
(solar, heliospheric and solar-planetary sciences, geology, geophysics and atmospheric sciences of planets, satellites and small bodies as well as cosmochemistry and exobiology).
