sed

I have a blacklist.txt file that contains keywords I want to remove using sed.

Here's what the blacklist.txt file contain

winston@linux ] $ cat blacklist.txt   
obscure
keywords
here
...

And here's what I have so far, but currently doesn't work.

  blacklist=$(cat blacklist.txt);
  output="filtered_file.txt"

  for i in $blacklist;
    do
      cat $input | sed 's/$i//g' >> $output
    done
