项目摘要
0201949 Edwards Catastrophic iron corrosion sometimes occurs in the presence of SRB with profound consequences. A theory of SRB induced iron corrosion is proposed based on the observations that reduced phosphorus species such as phosphine (PH3) can catalyze the rate limiting reaction in iron corrosion, and that phosphates added to iron metal or drinking water as corrosion inhibitors can serve as the source of catalyst in the presence of sulfides.Three phases of experimental work are planned to examine aspects of reduced phosphorus species chemistry. This includes 1) development of analytical protocols and a survey of reduced P occurrence, 2) examination of the aqueous chemistry of reduced P and pathways leading to its production, and 3) defining the role of reduced phisphorus in iron corrosion.This research, although fundamental, has important applications to the engineering community. The investigators note that there is ample evidence supporting the idea that reduced phosphorus could catalyze iron corrosion under conditions present in water distribution systems. Therefore, where these forms of phosphorus are present, there can be high costs associated with pipe replacement.
0201949 Edwards灾难性的铁腐蚀有时会在硫酸盐还原菌存在下发生,并产生深远的后果。 根据还原态磷(PH3)对铁腐蚀的催化作用,以及在硫化物存在下,磷酸盐作为缓蚀剂对铁腐蚀的催化作用,提出了硫酸盐还原菌引起铁腐蚀的理论。 这包括1)分析协议的开发和还原磷发生的调查,2)检查还原磷的水化学和导致其产生的途径,和3)确定还原phisphorus在铁腐蚀中的作用。 研究人员指出,有充分的证据支持这样一种观点,即在配水系统中存在的条件下,还原的磷可以催化铁的腐蚀。 因此,在存在这些形式的磷的情况下,可能存在与管道更换相关的高成本。
