Various ways of sample preparation for subsequent analysis of titanium(IV) oxide white pigment are represented. Three different procedures: digestion in various mediums, lithium metaborate fusion and pressure dissolution with hydrofluoric acid are precisely represented and considering accuracy, precision, blank values, time of analysis and general procedure’s simplicity, the last procedure is undoubtedly the most appropriate one.
