X-ray diffraction and particle size measurements indicated that the precipitates were a mixture of hydroxyapatite and calcium-deficient hydroxyapatite, with size ranging from 3 to 10 μm. Electroflotation with Na-oleate as surfactant was used to recover the precipitates. The surfactant adsorption was evaluated through zeta potential measurements. The influence of Na-oleate concentration, pH and bubble size on phosphate recovery was investigated. In the absence of Na-oleate, a phosphate recovery of 50% was achieved, while in the presence of 20 mg L-1 of Na-oleate it was increased to 90%, at pH 11. The phosphate recovery also increased with Ca(OH)2 concentration increase and bubble size decrease, reaching 100% at 300 mg L-1 Ca(OH)2 and bubble size around 39 µm.","descriptionType":"Abstract"}],"geoLocations":[],"fundingReferences":[],"xml":"PD94bWwgdmVyc2lvbj0iMS4wIiBlbmNvZGluZz0iVVRGLTgiPz4KPHJlc291cmNlIHhtbG5zPSJodHRwOi8vZGF0YWNpdGUub3JnL3NjaGVtYS9rZXJuZWwtNCIgeG1sbnM6eHNpPSJodHRwOi8vd3d3LnczLm9yZy8yMDAxL1hNTFNjaGVtYS1pbnN0YW5jZSIgeHNpOnNjaGVtYUxvY2F0aW9uPSJodHRwOi8vZGF0YWNpdGUub3JnL3NjaGVtYS9rZXJuZWwtNCBodHRwOi8vc2NoZW1hLmRhdGFjaXRlLm9yZy9tZXRhL2tlcm5lbC00LjEvbWV0YWRhdGEueHNkIj4KICA8aWRlbnRpZmllciBpZGVudGlmaWVyVHlwZT0iRE9JIj4xMC42MDg0L005LkZJR1NIQVJFLjU4NjEyODY8L2lkZW50aWZpZXI+CiAgPGNyZWF0b3JzPgogICAgPGNyZWF0b3I+CiAgICAgIDxjcmVhdG9yTmFtZT5TLiBHLiBkYSBDcnV6PC9jcmVhdG9yTmFtZT4KICAgIDwvY3JlYXRvcj4KICAgIDxjcmVhdG9yPgogICAgICA8Y3JlYXRvck5hbWU+TS4gQi4gZGUgTS4gTW9udGU8L2NyZWF0b3JOYW1lPgogICAgPC9jcmVhdG9yPgogICAgPGNyZWF0b3I+CiAgICAgIDxjcmVhdG9yTmFtZT5BLiBKLiBCLiBEdXRyYTwvY3JlYXRvck5hbWU+CiAgICA8L2NyZWF0b3I+CiAgPC9jcmVhdG9ycz4KICA8dGl0bGVzPgogICAgPHRpdGxlPkVsZWN0cm9mbG90YXRpb24gb2YgcHJlY2lwaXRhdGVkIHBob3NwaGF0ZSBmcm9tIHN5bnRoZXRpYyBzb2x1dGlvbjwvdGl0bGU+CiAgPC90aXRsZXM+CiAgPGRlc2NyaXB0aW9ucz4KICAgIDxkZXNjcmlwdGlvbiBkZXNjcmlwdGlvblR5cGU9IkFic3RyYWN0Ij4mbHQ7ZGl2Jmd0OyZsdDtwJmd0O0FCU1RSQUNUIFRoZSBwaG9zcGhhdGUgcmVjb3ZlcnkgZnJvbSBhIDIwIG1nIEwtMSBOYTJIUE80IHNvbHV0aW9uIHRocm91Z2ggcHJlY2lwaXRhdGlvbiB3aXRoIENhKE9IKTIgZm9sbG93ZWQgYnkgZWxlY3Ryb2Zsb3RhdGlvbiB3YXMgZXZhbHVhdGVkLiBYLXJheSBkaWZmcmFjdGlvbiBhbmQgcGFydGljbGUgc2l6ZSBtZWFzdXJlbWVudHMgaW5kaWNhdGVkIHRoYXQgdGhlIHByZWNpcGl0YXRlcyB3ZXJlIGEgbWl4dHVyZSBvZiBoeWRyb3h5YXBhdGl0ZSBhbmQgY2FsY2l1bS1kZWZpY2llbnQgaHlkcm94eWFwYXRpdGUsIHdpdGggc2l6ZSByYW5naW5nIGZyb20gMyB0byAxMCDOvG0uIEVsZWN0cm9mbG90YXRpb24gd2l0aCBOYS1vbGVhdGUgYXMgc3VyZmFjdGFudCB3YXMgdXNlZCB0byByZWNvdmVyIHRoZSBwcmVjaXBpdGF0ZXMuIFRoZSBzdXJmYWN0YW50IGFkc29ycHRpb24gd2FzIGV2YWx1YXRlZCB0aHJvdWdoIHpldGEgcG90ZW50aWFsIG1lYXN1cmVtZW50cy4gVGhlIGluZmx1ZW5jZSBvZiBOYS1vbGVhdGUgY29uY2VudHJhdGlvbiwgcEggYW5kIGJ1YmJsZSBzaXplIG9uIHBob3NwaGF0ZSByZWNvdmVyeSB3YXMgaW52ZXN0aWdhdGVkLiBJbiB0aGUgYWJzZW5jZSBvZiBOYS1vbGVhdGUsIGEgcGhvc3BoYXRlIHJlY292ZXJ5IG9mIDUwJSB3YXMgYWNoaWV2ZWQsIHdoaWxlIGluIHRoZSBwcmVzZW5jZSBvZiAyMCBtZyBMLTEgb2YgTmEtb2xlYXRlIGl0IHdhcyBpbmNyZWFzZWQgdG8gOTAlLCBhdCBwSCAxMS4gVGhlIHBob3NwaGF0ZSByZWNvdmVyeSBhbHNvIGluY3JlYXNlZCB3aXRoIENhKE9IKTIgY29uY2VudHJhdGlvbiBpbmNyZWFzZSBhbmQgYnViYmxlIHNpemUgZGVjcmVhc2UsIHJlYWNoaW5nIDEwMCUgYXQgMzAwIG1nIEwtMSBDYShPSCkyIGFuZCBidWJibGUgc2l6ZSBhcm91bmQgMzkgwrVtLiZsdDsvcCZndDsmbHQ7L2RpdiZndDs8L2Rlc2NyaXB0aW9uPgogIDwvZGVzY3JpcHRpb25zPgogIDxzdWJqZWN0cz4KICAgIDxzdWJqZWN0IHNjaGVtZVVSST0iaHR0cDovL3d3dy5hYnMuZ292LmF1L2F1c3N0YXRzL2Fic0AubnNmLzAvNkJCNDI3QUI5Njk2QzIyNUNBMjU3NDE4MDAwNDQ2M0UiIHN1YmplY3RTY2hlbWU9IkZPUiI+OTA0OTkgQ2hlbWljYWwgRW5naW5lZXJpbmcgbm90IGVsc2V3aGVyZSBjbGFzc2lmaWVkPC9zdWJqZWN0PgogIDwvc3ViamVjdHM+CiAgPHB1Ymxpc2hlcj5TY2lFTE8gam91cm5hbHM8L3B1Ymxpc2hlcj4KICA8cHVibGljYXRpb25ZZWFyPjIwMTg8L3B1YmxpY2F0aW9uWWVhcj4KICA8ZGF0ZXM+CiAgICA8ZGF0ZSBkYXRlVHlwZT0iQ3JlYXRlZCI+MjAxOC0wMi0wNzwvZGF0ZT4KICAgIDxkYXRlIGRhdGVUeXBlPSJVcGRhdGVkIj4yMDE4LTAyLTA3PC9kYXRlPgogIDwvZGF0ZXM+CiAgPHJlc291cmNlVHlwZSByZXNvdXJjZVR5cGVHZW5lcmFsPSJEYXRhc2V0Ij5EYXRhc2V0PC9yZXNvdXJjZVR5cGU+CiAgPHNpemVzPgogICAgPHNpemU+OTUzNDkgQnl0ZXM8L3NpemU+CiAgPC9zaXplcz4KICA8cmVsYXRlZElkZW50aWZpZXJzPgogICAgPHJlbGF0ZWRJZGVudGlmaWVyIHJlbGF0ZWRJZGVudGlmaWVyVHlwZT0iRE9JIiByZWxhdGlvblR5cGU9IklzU3VwcGxlbWVudFRvIj4xMC4xNTkwLzAxMDQtNjYzMi4yMDE3MDM0M3MyMDE2MDA0MDwvcmVsYXRlZElkZW50aWZpZXI+CiAgPC9yZWxhdGVkSWRlbnRpZmllcnM+CiAgPHJpZ2h0c0xpc3Q+CiAgICA8cmlnaHRzIHJpZ2h0c1VSST0iaHR0cHM6Ly9jcmVhdGl2ZWNvbW1vbnMub3JnL2xpY2Vuc2VzL2J5LzQuMC8iPkNDIEJZIDQuMDwvcmlnaHRzPgogIDwvcmlnaHRzTGlzdD4KPC9yZXNvdXJjZT4=","url":"https://scielo.figshare.com/articles/Electroflotation_of_precipitated_phosphate_from_synthetic_solution/5861286","contentUrl":null,"metadataVersion":1,"schemaVersion":"http://datacite.org/schema/kernel-4","source":"mds","isActive":true,"state":"findable","reason":null,"viewCount":0,"viewsOverTime":[],"downloadCount":0,"downloadsOverTime":[],"referenceCount":0,"citationCount":0,"citationsOverTime":[],"partCount":0,"partOfCount":0,"versionCount":0,"versionOfCount":0,"created":"2018-02-07T02:43:18.000Z","registered":"2018-02-07T02:43:19.000Z","published":"2018","updated":"2020-08-30T18:13:07.000Z"},"relationships":{"client":{"data":{"id":"figshare.ars","type":"clients"}},"provider":{"data":{"id":"otjm","type":"providers"}},"media":{"data":{"id":"10.6084/m9.figshare.5861286","type":"media"}},"references":{"data":[]},"citations":{"data":[]},"parts":{"data":[]},"partOf":{"data":[]},"versions":{"data":[]},"versionOf":{"data":[]}}}}
