Possible Interaction: Chlorine and Copper

“Meanwhile, according to element balance analysis, removal of chlorine from the catalyst surface was also promoted by Cu doping.”

“In the obtained data it was observed that the corrosion rate and the release of copper increases with the chlorine concentration.”

“In addition, it has been reported that the use of copper pipes triggers chlorine decay and results in the formation of chlorine disinfection byproducts.”

“Increased concentration of chlorine and higher ambient temperature were found to expedite the corrosion of copper.”

“In the presence of chlorine , the flue gas moisture reduced the volatility of Pb, Zn and Cu due to the transformation of the more volatile metal chlorides into less volatile metal oxides, and the reduction became significant as chlorine content increase.”

“ Copper and chlorine are correlated and, thus cannot be distinguished.”

“Distribution ratios of metal elements to MFA were generally determined by volatility of the metal element, but chlorine content in feedstock had a significant effect on Cu and a marginal effect on Pb.”

“One reason for weaker efficiency of chlorine in copper pipes was that its concentration declined more rapidly in the copper pipes than in the PE pipes.”

“Soluble copper release increased at lower … and lower pH. Low levels of free chlorine (0.7 mg/…) slightly increased copper release at pH 9.5, in marked contrast to the dramatic reductions in copper release … have been observed in soft waters in which Type III pitting corrosion is occurring.”

“The presence of>10ppm of chlorine , however, interfered with the recovery of copper.”
