This rare kanji has no clear standalone meaning. Treat its meaning as uncertain.
泧 combines 氵 (water) with 戉, but the exact historical development and original meaning are uncertain.
With water 氵 beside 戉, imagine a swift, cutting movement through water, but the true meaning is unclear.
For エツ, picture an eddy of water swirling around the blade-like 戉: eddy -> エツ, though the reading is rare.
