Speciation of heavy metals in electroplating industry sludge and wastewater residue using inductively coupled plasma

Inductively Coupled Plasma: the Future of Heavy Metals Testing

The USP has proposed using inductively coupled plasma (ICP) for determining heavy metals in drug articles to replace the USP <231> heavy metals test. While the current USP <231> procedure will detect Pb, Hg, Bi, As, Sb, Sn, Cd, Ag, Cu and Mo, the proposed method will test for Al, Sb, As, Be, B, Cd, Cr, Co, Cu, In, Ir, Fe, Pb, Li, Mg, Mn, Hg, Mo, Ni, Os, Pd, Pt, Rh, Rb, Ru, Se, Sr, Tl, Sn, W and...

Heavy metals determination in honey samples using inductively coupled plasma-optical emission spectrometry

BACKGROUND Honey contains a complex mixture of carbohydrates and other minor substances. Elements are minor constituents of honey that may threaten the human health in excess concentrations. So, determining the metals in honey helps its quality control as a food product. The aim of this study was to determine the concentrations of some metals in Iranian honey. METHODS This study was performed...

Pollution potential and ecological risk of heavy metals in municipal wastewater treatment plants sludge

Background and Objective: Application of sewage sludge contaminated with heavy metals may cause health and ecological concern. Ecological risk and heavy metals content of sewage sludge from wastewater treatment plants of East Azerbaijan province were evaluated in the present study. Materials and Methods: Nine composite samples were taken and analyzed for heavy metals. The geo-accumulation inde...

Electrokinetic enhancement removal of heavy metals from industrial wastewater sludge.

An enhanced electrokinetic process for removal of metals (Cr, Cu, Fe, Ni, Pb, Zn) from an industrial wastewater sludge was performed. The electrokinetic experiments were conducted under a constant potential gradient (1.25 V cm(-1)) with processing fluids of tap water (TW), sodium dodecylsulfate (SDS) and citric acid (CA) for 5 days. Results showed that metal removal efficiency of heavy metals f...
