Abstract: The present Invention relates to a method of and apparatus for feeding a chemical into a liquid flow. The method and apparatus according to the invention are most preferably utilized for feeding a retention aid into fiber suspension flow going to the headbox of a paper machine so that in a mixing apparatus (34) feeding liquid is added into said retention chemical solution, prior to introducing said solution into the fiber suspension flow (70) guided to the paper machine, which feeding liquid is preferably some circulation water from the paper mill or some other non-clean liquid.
