Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
A method of determination of metals in pipe scale samples from water supply network was developed by Flame Atomic Absorption Spectrometry. Digestion of pipe scale samples from drinking water distribution systems of the Yellow River and Laoshan Reservoir in Qingdao were carried out with concentrated hydrochloric acid, then under the best condition of determination, using the standard curve method, the amounts of Fe, Mn, Ca, Mg, Cu and Zn in pipe scales were determined by Flame Atomic Absorption Spectrometry. The analytical results indicated that the six metal elements were all detected, while Cu in the Laoshan Reservoir pipe scale samples were not detected out. The concentration of Fe is the highest, amounting to 610.75 mg/g, taking up more than 95 percent. However, concentions of other metal elements were all below 5.00 mg/g, less than 1 percent.
