The addition polymerization was carried out with ammonium persulfate as the initiator, at different acrylamide (AM) concentrations. The SAG-g-PAM copolymers were evaluated by FTIR and 13C NMR spectroscopies, thermogravimetric analysis, grafting efficiency (%GE) and intrinsic viscosity in NaCl solution at 25 °C. Graft copolymers could be obtained in reaction lasting until 10 min by using ultrasound energy with grafting efficiency above 75%. The decolorization efficiency and adsorption capacity of the SAG- g-PAM copolymers were investigated in the adsorption of methylene blue (MB). The dye adsorption was pH dependent, and adsorption capacity (69.13 mg/g) maxima was at pH 10. All the graft copolymers have shown the same decolorization efficiency (99%), and the best one for MB removing is the SAG-g-PAM6 (%GE = 75%), since lower acrylamide content is required in the synthesis.","descriptionType":"Abstract"}],"geoLocations":[],"fundingReferences":[],"xml":"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","url":"https://scielo.figshare.com/articles/Ultrasound-assisted_synthesis_of_polyacrylamide-grafted_sodium_alginate_and_its_application_in_dye_removal/6693410","contentUrl":null,"metadataVersion":2,"schemaVersion":"http://datacite.org/schema/kernel-4","source":"mds","isActive":true,"state":"findable","reason":null,"viewCount":0,"viewsOverTime":[],"downloadCount":0,"downloadsOverTime":[],"referenceCount":1,"citationCount":0,"citationsOverTime":[],"partCount":0,"partOfCount":0,"versionCount":0,"versionOfCount":0,"created":"2018-06-27T02:43:02.000Z","registered":"2018-06-27T02:43:02.000Z","published":"2018","updated":"2020-08-28T22:47:26.000Z"},"relationships":{"client":{"data":{"id":"figshare.ars","type":"clients"}},"provider":{"data":{"id":"otjm","type":"providers"}},"media":{"data":{"id":"10.6084/m9.figshare.6693410","type":"media"}},"references":{"data":[{"id":"10.1590/0104-1428.11316","type":"dois"}]},"citations":{"data":[]},"parts":{"data":[]},"partOf":{"data":[]},"versions":{"data":[]},"versionOf":{"data":[]}}}}
