In this paper, the ability of chrome shavings to remove motor oils, oily wastes and hydrocarbons from water has been studied. To determine amount of hydrocarbons sorbed on tanned wastes, a FT-NIR methodology was used and a multivariate calibration based on partial least squares (PLS) was employed for data treatment. The light density, porous tanned waste granules float on the surface of water a...

In the poor zones of sub-Saharan Africa, the conventional drinking water network is very weak. The populations use alternative groundwater sources which are wells and springs. However, because of urbanization, the groundwater sources are degrading gradually making pure, safe, healthy and odourless drinking water a matter of deep concern. There are many pollutants in groundwater due to seepage o...

Water is today considered to be a vital and limited resource due to industrial development and population growth. Developing appropriate water treatment techniques, to ensure a sustainable management, represents a key point in the worldwide strategies. By removing both organic and inorganic species using techniques based on coupling membrane processes and appropriate complexing agents to bind p...

In this paper, Michael Boyer attempted to determine the magnitude of an emerging environmental threat: the flow of radioactive materials from industrial sites in the former Soviet Union to rivers and other bodies of water, which in turn empty into the Arctic Ocean. While such radioactive pollution is harmful regardless of its destination, the Arctic’s precarious ecology is particularly vulnerab...

the present study aimed at investigating and estimating the amount of damage caused by waste water pollution of water desalinators in the south pars special zone. the main reasons for conducting this study were to investigate the creation of environmental pollutants as a result of the development and expansion of different industries in the south pars zone, as well as the ecological sensitivity...

We describe the use of catalytically self-propelled microjets (dubbed micromotors) for degrading organic pollutants in water via the Fenton oxidation process. The tubular micromotors are composed of rolled-up functional nanomembranes consisting of Fe/Pt bilayers. The micromotors contain double functionality within their architecture, i.e., the inner Pt for the self-propulsion and the outer Fe f...

Partitioning of organic pollutants is essential to their fate, mobility and removal from water and soil. To study the partitioning behavior of selected alkylphenols, bisphenol A, phthalates and polycyclic aromatic hydrocarbons (PAHs), a method for separating the truly dissolved and colloidal phase of organic pollutants was developed, verified and applied to samples of landfill leachate and stor...

Water quality degradation in river systems has caused great concerns all over the world. Identifying the spatial distribution and sources of water pollutants is the very first step for efficient water quality management. A set of water samples collected bimonthly at 12 monitoring sites in 2009 and 2010 were analyzed to determine the spatial distribution of critical parameters and to apportion t...

Watersheds are recognized as the most effective management unit for the protection of water resources. For surface water supplies that use water from upstream watersheds, evaluating threats to water quality and implementing a watershed management plan are crucial for the maintenance of drinking water safe for humans. The aim of this article is to establish a risk assessment model that provides ...

In aqueous medium at room temperature Ag(I) forms a metallogel with vanadate ions which doesn't have any carbon in the gel skeleton. The serendipitously discovered inorganic gel, which involves a reasonably large volume of water, is capable of sequestering gas, dye and toxic pollutants from water bodies.
