Lead

The focus of this paper is to test the ability of a commercially available nanofiltration membrane (AFC 80) to remove polluting and toxic Pb(II) ions from aqueous solutions in order to meet the USEPA guidelines regarding the toxicity threshold limits. The investigation has been conducted for aqueous

Activated carbon was prepared from hazelnut husks with zinc chloride activation at 973 K in nitrogen atmosphere. BET surface area of the activated carbon was found 1092 m2g!1. The removal of Cu (II) and Pb (II) ions from aqueous solutions was studied by batch method. The effects of initial pH, conta

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 “1st South-Eastern European Interlaboratory Study WATER ANALYSIS-2003” was organized in the period of November 2003 to February 2004, on the basis of European and international experiences. The total of 38 laboratories took part in “WATER ANALYSIS-2003”. Three laboratories were from Greece, one

Precipitation of lead and bromide, followed by careful crystallization, is usually discussed when the production or synthesis of lead bromide is involved. However, there are numerous issues, especially concerning the precipitation of lead bromide hydroxide (Pb(OH)Br) and its derivatives in the neutr

In the present study, the ability of natural zeolite clinoptilolite and bentonite (clay) to remove Pb(II) from aqueous solutions has been investigated in batch reactors with a maximum contact time of 120 min. Adsorption tests of Pb(II) were carried out using a solution concentration of 1,036 ppm at

Lead is a highly toxic heavy metal, found in water and air, which should be treated. Lead removal from wastewater is an important problem in battery industries. The separation process by means of electrodialysis (ED) shows several advantages such as highly selective desalination, high water recovery

In this paper the pilot tests of a recycling process for removing lead form nitric acid solutions have been presented. At first batch tests were performed. Permeate yields up to 80% could be achieved in these tests. Corresponding to these yields the lead concentrations rose up to 70 g/l. Due to the

In this work two distinct (flocculent and non-flocculent) yeast wastes from Portuguese breweries were used for the selective removal of Cu2+, Cd2+ and Pb2+ from aqueous solutions. One of the goals was to establish both the pH profiles for the removal of each metal ion (1.0 mM) and the effect on the
