We have performed a spectral decomposition to search for dual active galacticnuclei (DAGNs) in the Sloan Digital Sky Survey (SDSS) quasars with $z<0.25$.Potential DAGN candidates are searched by referencing velocity offsets andspectral shapes of double-peaked [O III] lines of known DAGNs. Out of 1271 SDSSquasars, we have identified 77 DAGN candidates. Optical and mid-infrareddiagnostic diagrams are used to investigate the ionizing source in the DAGNcandidates. The optical diagnostic analysis suggests 93\% of them are poweredby AGNs, and mid-infrared diagnostic analysis suggests 97\% are powered byAGNs. About 1/3 of the SDSS images of the DAGN candidates show signs of tidalinteraction, but we are unable to identify double nuclei in most of them due tothe low spatial resolution of the archival imaging data available for most ofthe sample. The radio-loud fraction of the DAGN candidates ($\sim$10\%) issimilar to that of typical AGNs.
