Algal cultivation in urban wastewater: an efficient way to reduce pharmaceutical pollutants

An efficient way to reduce losses of left-handed metamaterials.

We propose a simple and effective way to reduce the losses in left-handed metamaterials by manipulating the values of the effective parameters R, L, and C. We investigate the role of losses of the short-wire pairs and the fishnet structures. Increasing the effective inductance to capacitance ratio, L/C, reduces the losses and the figure of merit can increase substantially, especially at THz fre...

Ibuprofen Removal from a Pharmaceutical Wastewater using Electro-Fenton Process: An Efficient Technique (RESEARCH NOTE)

The aim of this research was to evaluate the effective parameters such as pH, current density (mA/cm2), H2O2/Fe2+ molar ratio, volume ratio of H2O2 to pharmaceutical wastewater (PhW) (ml/l) and reaction time (min) on the electro-Fenton process for the ibuprofen (as a pharmaceutical waste in water) removal. Since a synthetic wastewater with the same concentration of ibuprofen in a real pharmaceu...

Modelling Human Exposure to Air Pollutants in an Urban Area

http://www.revistadechimie.ro 61 Road traffic is one of the main sources of atmospheric pollution in urban areas, where the contribution of traffic flows, congestions and high population density typically increases the exposure of the settled population to pollutants [1-3]. One of the most important family of traffic-related pollutants is represented by nitrogen oxides (NOx), whose main contrib...

Efficient Removal of Diclofenac from Pharmaceutical Wastewater Using Impregnated Zeolite Catalyst in Heterogeneous Fenton Process

In this study, we report removal of Diclofenac (DCF) through heterogeneous Fenton process using Fe-ZSM-5 catalyst. The parent catalyst was prepared by hydrothermal technique. Fe species were introduced by wet impregnation. Characterization of the catalysts was carried out using XRD, FT-IR, FE-SEM, N2 adsorption-desorption, NH3-TPD, and acidimetric-alkalimetric titration. The bimetallic catalyst...
