Heavy metals

In this study fixed-bed sorption filters are filled with an iron based sorbent (ferrosorp plus, FP) and used to remove a range of heavy metals (i.e. As, Cd, Cr, Cu, Ni, and Zn) from polluted water. It is found that FP is very effective at simultaneous removal of the heavy metals, and the magnitude o

Sodium alginate extracted from the brown algae Laminaria digitata was used to prepare metal sorbing beads. Their metal binding properties were investigated with respect to copper and cadmium ions in single and binary metal solutions. Their behaviour in batch kinetic experiments and in a flow through

The present work is a comprehensive evaluation of drinking water quality from various regions of Greece. The physicochemical parameters investigated were conductivity, total dissolved solids and pH, as well as related to the treatment of drinking water such as chloride, potassium, calcium, magnesium

Zeolites are naturally occurring minerals characterized by high cation exchange and adsorption capacity and, thus, are used for metal uptake from sewage sludge subjected to composting process. In the present paper, changes in the physicochemical characteristics of sewage sludge samples after compost

Physicochemical parameters, natural radioactivity and heavy metals on the surface waters of rivers in Epirus (Aoos, Kalamas, Louros), Macedonia (Aliakmonas) and Thessalia (Pinios) were measured during the period May 2004–May 2006 in three sampling sites of each river. All the determined metal concen

The effective removal of heavy metals from aqueous wastes is among the most important issues for many industrialized countries. Removal of lead (II) and copper (II) from aqueous solutions were studied using pomegranate peel (raw), activated carbon prepared from pomegranate peel (AC1) and activated c

The emphasis on increased reuse of drainage water for irrigation is essential as Egypt expands its agricultural base to meet the food requirements for rapidly population growth rate. The Government of Egypt implemented El-Salaam Canal project to reuse drainage water, to create new communities along

The Axios/Vardar River, an interboundary river located in the Balkan Peninsula, drains the region of southern Serbia, almost 80% of the Former Yugoslav Republic of Macedonia territory and some parts of northern Greece. This study is based upon long-term data (1979–2003) of nitrate, nitrite, ammonium

A lot of small and shallow bays that exist along the extended Greek coastline differ significantly from the open sea in the fluctuation of hydrological parameters, the degree of eutrophication and the concentration of pollutants. These characteristics can sometimes create environmental conditions th
