Abstract

The invention relates to a method for phosphating the surface of a metal with a phosphating solution, comprising an accelerator, whereby the concentration of accelerator is determined using a biochemical hydrogen peroxide sensor. For example, a glucose oxidase immobilised on a support can be used.
