XRD analysis indicated the trimetallic particles present in zero-valent form of all three components. Trimetallic Pd\/Fe\/Al particles showed a very rapid degradation of carbon tetrachloride leading to a surface normalized rate constant (kSA) of approximately 0.03\u2009L\/h\/m2, two orders of magnitude higher than that of reported data on zero-valent iron particles under near neutral pH conditions. Hydrocarbons including methane and ethane were the major products that accounted for about 38% and 27% of the carbon tetrachloride lost, respectively. Repetitive addition of carbon tetrachloride showed no loss of activity of Pd\/Fe\/Al particles for more than 20 cycles. In the absence of palladium, the degradation rate decreased by a factor of 10 suggesting palladium serves as a catalyst. Analysis of anions in the solution revealed that the chloride accounted for 75% of the carbon tetrachloride lost. Metallic ions for aluminum and iron were determined to be about 0.02 and 20\u2009mg\/L, respectively at the end of the experiment. No palladium ion was measured.<\/jats:p>","DOI":"10.2166\/wst.2010.303","type":"journal-article","created":{"date-parts":[[2010,7,2]],"date-time":"2010-07-02T10:32:07Z","timestamp":1278066727000},"page":"202-208","update-policy":"http:\/\/dx.doi.org\/10.2166\/iwapcrossmarkpolicypage","source":"Crossref","is-referenced-by-count":16,"title":["Trimetallic Pd\/Fe\/Al particles for catalytic dechlorination of chlorinated organic contaminants"],"prefix":"10.2166","volume":"62","author":[{"given":"Chang-Chieh","family":"Huang","sequence":"first","affiliation":[{"name":"Department of Civil and Environmental Engineering, National University of Kaohsiung, Kaohsiung 811, Taiwan E-mail: d97541002@ntu.edu.tw"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hsing-Lung","family":"Lien","sequence":"first","affiliation":[{"name":"Department of Civil and Environmental Engineering, National University of Kaohsiung, Kaohsiung 811, Taiwan E-mail: d97541002@ntu.edu.tw"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"945","container-title":["Water Science and Technology"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/iwaponline.com\/wst\/article-pdf\/62\/1\/202\/446205\/202.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"syndication"},{"URL":"http:\/\/iwaponline.com\/wst\/article-pdf\/62\/1\/202\/446205\/202.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2020,3,27]],"date-time":"2020-03-27T23:36:20Z","timestamp":1585352180000},"score":1,"resource":{"primary":{"URL":"https:\/\/iwaponline.com\/wst\/article\/62\/1\/202\/14649\/Trimetallic-PdFeAl-particles-for-catalytic"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2010,7,1]]},"references-count":0,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2010,7,1]]}},"URL":"https:\/\/doi.org\/10.2166\/wst.2010.303","relation":{},"ISSN":["0273-1223","1996-9732"],"issn-type":[{"value":"0273-1223","type":"print"},{"value":"1996-9732","type":"electronic"}],"subject":[],"published-other":{"date-parts":[[2010,7,1]]},"published":{"date-parts":[[2010,7,1]]}}}
