Sentence examples for natural pollutant from inspiring English sources

This work may not only provide beneficial information to design and synthesis of effective composites system, but also present a new way to remove the refractory natural pollutant.

From this preliminary study, we have demonstrated that ZnO CuO composite NMs enhance Fenton-type photo-decomposition of humic acid, a natural pollutant present in surface water, by H2O2 under solar irradiation and suggested that electron transfer from CB of ZnO in the ZnO CuO nanocomposite becomes faster to OH radical because of the presence of p n hetero-junction at the composite NMs.

We report here the synthesis of CuO-doped ZnO composite nanomaterials (NMs) by chemical route and demonstrated for the first time that these NMs are efficient catalysts for H2O2-assisted photo-decomposition (photo-Fenton type catalyst) of humic acid, a natural pollutant of surface water by solar irradiation.

In describing hypothesized market, the potential future groundwater contamination by types of pollution such as agricultural chemical, possibility of natural pollutants iron and arsenic was discussed.

Saline soil, in particular, is extremely corrosive to ferrous metal pipelines mainly due to the abundant chloride contents, one of the most substantial natural pollutants in saline-alkaline soils4.
