The enhancement of lead removal was approximately 21 to 37% by ferrate pretreatment at a dosage of 1 to 5 mg\/L. The enhanced removal of cadmium by ferrate pretreatment at a dosage of 1 to 5 mg\/L exceeded the removal by alum coagulation alone 2\u2010 to 12\u2010fold. Cadmium is much more difficult to remove than lead in alum coagulation. The performance of ferrate in enhancing the removal of lead and cadmium in alum coagulation was better than that of ferric chloride. The removal of lead and cadmium was highly pH\u2010dependent, following the general trend of higher pH being related to higher removal. Satisfactory removal of cadmium could be expected by ferrate pretreatment combined with adjusting the pH of the water.<\/jats:p>","DOI":"10.2175\/106143007x212148","type":"journal-article","created":{"date-parts":[[2007,11,3]],"date-time":"2007-11-03T18:52:30Z","timestamp":1194115950000},"page":"2420-2426","source":"Crossref","is-referenced-by-count":32,"title":["Enhanced Removal of Lead(II) and Cadmium(II) from Water in Alum Coagulation by Ferrate(VI) Pretreatment"],"prefix":"10.1002","volume":"79","author":[{"given":"Yong\u2010mei","family":"Liang","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ma","family":"Jun","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wei","family":"Liu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2007,11]]},"reference":[{"key":"e_1_2_5_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.apgeochem.2004.10.004"},{"key":"e_1_2_5_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/0021-9797(81)90063-1"},{"key":"e_1_2_5_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0043-1354(96)00161-3"},{"key":"e_1_2_5_5_1","doi-asserted-by":"publisher","DOI":"10.1061\/(ASCE)0733-9372(1983)109:5(1159)"},{"key":"e_1_2_5_6_1","doi-asserted-by":"publisher","DOI":"10.1061\/(ASCE)0733-9372(1983)109:1(36)"},{"key":"e_1_2_5_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcis.2005.01.045"},{"issue":"23","key":"e_1_2_5_8_1","doi-asserted-by":"crossref","first-page":"6058","DOI":"10.1021\/ja00752a016","article-title":"Mechanism of Isotopic Oxygen Exchange and Reduction of Ferrate (VI) Ion (FeO2\n                  4\n                  \u2010\u2010).","volume":"93","author":"Goff H.","year":"1971","journal-title":"J.
