The behaviour of Fe3+ cations in HY zeolite which had been subjected to various treatments has been studied by X-ray phtoelectron spectroscopy. The self-reduction of Fe3+ to Fe2+ after vacuum heat-treatment and the partial ...

Electromotive force measurements using the cell Pt|H2(g,1 atm)|HCl(m), dioxan(X), H2O(Y)|AgCl(s)|Ag have been made at nine different temperatures from 15 to 55°C at five intervals in eighteen dioxan + water solvent mixtures. ...

Over the past several decades, urbanisation has spread rapidly over the globe. Research on the viability of urban stormwater drainage systems and the search for solutions to the related problems constitute an important ...

This study investigated the effect of the landscape pattern of permeable/impermeable patches on NO3−-N and particulate organic nitrogen (PON) concentrations during stormwater runoff transport and their source contributions. ...

Flooding is the most frequent and destructive natural disaster currently facing Sri Lanka. Rapid urbanization and changing precipitation patterns are exacerbating the situation, leading to extensive socio-economic damage ...

Sustainable stormwater management is important to mitigate stormwater pollution as well as reuse stormwater resources. This chapter initially discusses the current environmental issues caused by stormwater pollution and ...

Suspended solids are an important pollutant in urban stormwater runoff. Past studies have mainly focused on a single transport stage of pollutants, constraining source identification of suspended solids at the catchment ...

This paper discusses the development of a glassy carbon electrode (GC) for the determination and electro-remediation of sulfamethazine (SMZ) in natural waters using multi-walled carbon nanotubes (MWCNT) and silver nanoparticles ...

Non-point source (NPS) pollution from stormwater runoff has become a major threat to urban water bodies. Rapid and reliable pollution profiling is essential for effective mitigation, yet early-stage stormwater management ...

Thermodynamic arguments are used to derive a simple expression for the Donnan equilibrium between a solution of charged colloid plus electrolyte and a solution of electrolyte alone. From it, expressions for the solute ...
