Copper

The process, called electrodeposition, was used for recovery of metals from aqueous solutions. The aqueous solutions of the sulfate forms of copper and cobalt metals were used as the catholyte solution and 0.1 M NaNO3 was used as an anolyte solution. The effect of current density, metal concentratio

The effect of pH, biosolid dosage, initial copper concentration, and contact time on copper removal from aqueous solutions using biosolids (waste sludge cake) was investigated through batch experiments. The copper removal increased by time and initial metal concentrations. The equilibrium time was a

We investigated the electrokinetic properties of sepiolite suspensions using the microelectrophoresis technique as a function of pH in the presence of various electrolytes such as, LiCl, NaCl, KCl, Cu(NO3)2, CaCl2, Pb(NO3)2, AlCl3 and Fe(NO3)3 and then, the adsorption of Cu(II) ion onto sepiolite fr

Copper rejections of a nanofiltration (NF) and a reverse osmosis (RO) membrane are investigated with coppersulfate and copper-nitrate solutions as test wastewaters. The copper content of the solutions represents the typical copper ion concentration of process waters from a textile coating plant, i.e

This paper considers the importance of automobiles as a continuing source of persistent pollutants in the environment, using the UK as a case study. The mass of lead, copper, zinc and polycyclic aromatic hydrocarbons (PAHs) being released by automobiles in the UK is estimated. It is shown that as ot

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

Slag, which consists of calcium oxide, aluminium oxide, and other metal oxides, is an abundant by-product in steel-making process. It has been used as adsorbents to remove various heavy metals and the major removal mechanisms are precipitation and adsorption on the surface of metal oxide. However, t

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 ability of natural zeolite (clinoptilolite) and exfoliated vermiculite to remove copper from aqueous solutions was studied in fixed bed column and batch reactors. The effect of agitation speed (0, 100, 200, 400 rpm), temperature (25, 45, 60°C), and particle size [2.5-5.0 mm, dust ( clinoptilolit

A study was carried out to examine the removal of copper from an aqueous solution by phosphate rock (PR). The adsorption method was applied and optimum conditions for adsorption were evaluated by changing various parameters; effects of pH, adsorbent concentration, initial metal concentration and con
