GALVANIC METHOD WITH ANALYSIS OF THE ELECTROLYTE BATH BY SOLID PHASE EXTRACTION

摘要

Disclosed is a method for the galvanic deposition of a metal coating from an electrolyte bath in which the concentrations of at least two components of the electrolyte bath are monitored and in which the following steps are carried out: a) a sample is removed from the electrolyte bath; b) the sample is fed to a column for solid phase extraction which contains a solid sorption agent; c) the column is subjected to a washing process with a first eluent, wherein the at least two components remain in the column and unwanted components are eluted from the column; d) the at least two components are eluted from the column by means of a second eluent; e) the concentrations of the at least two components in the eluate obtained in step (d) are determined without the components being separated from each other. The use of poIy(divinylbenzene-co-N-vinylpyrrolidon) for the solid phase extraction is particularly advantageous.
