Morphology

dechlorinate = chlorinate (semi-transparent) = de + chlorin + ate

This sense is a straightforward reversative or removal use of 'de-' applied to 'chlorinate', meaning to remove chlorine after chlorination.

Etymology

The word dechlorinate breaks into de- meaning 'remove' and chlorine, the greenish chemical used in pools. So to dechlorinate is to 'take the chlorine out' of water to make it safe for fish and people.
