Ah, that is because you haven't changed the catcode of '@' character
to 11 with \makeatletter. 

However, \twocolumn[\@maketitle] is not to be used in your document at
all. You have to redefine \@maketitle to include abstract environment
too so that when you issue the \maketitle command in your document, it
will invoke \twocolumn[\@maketitle] internally and your objectives
will be met.

Best.
