To control P release, in-situ control technology with lanthanum (La) modified bentonite clay (Phoslock\u00ae) was proposed and its effectiveness was tested and evaluated both in laboratory and field trials. The results of static and dynamic simulation experiments under different environmental conditions showed that with the application rate of Phoslock\u00ae at 0.5 kg\/m2, the orthophosphate (PO4-P) concentration of the overlying water decreased to a low level (\u22640.02 mg\/L) within 10 days. Even under anaerobic and high pH (pH = 9.0) conditions, the phosphate release suppression efficiency reached 98.3%, and the P-release rate was \u22128.20 mg\/m2 d (negative value indicates P adsorption by Phoslock\u00ae). The monitoring data of the field sediments rehabilitation project were consistent with the results achieved in laboratory experiments, thus showing that the application of Phoslock\u00ae could inhibit the internal P release effectively.<\/jats:p>","DOI":"10.2166\/wst.2012.927","type":"journal-article","created":{"date-parts":[[2012,3,23]],"date-time":"2012-03-23T09:11:57Z","timestamp":1332493917000},"page":"1190-1199","update-policy":"https:\/\/doi.org\/10.2166\/iwapcrossmarkpolicypage","source":"Crossref","is-referenced-by-count":14,"title":["Research and application of in-situ control technology for sediment rehabilitation in eutrophic water bodies"],"prefix":"10.2166","volume":"65","author":[{"given":"Bo","family":"Liu","sequence":"first","affiliation":[{"name":"Tianjin Hydraulic Research Institute, No. 60, Friendship Rd, Hexi District, Tianjin, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xuegong","family":"Liu","sequence":"first","affiliation":[{"name":"Tianjin Hydraulic Research Institute, No. 60, Friendship Rd, Hexi District, Tianjin, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jie","family":"Yang","sequence":"first","affiliation":[{"name":"Tianjin Hydraulic Research Institute, No. 60, Friendship Rd, Hexi District, Tianjin, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David E.
