ABSTRACT:
The invention relates to a process for determining water in samples containing water. This process is characterized in that a solvatochromic compound is added to a solution or dispersion of the sample in a solvent or directly to the liquid sample, the solvatochromism band .lambda..sub.max in the UV-vis-spectrum is determined, the E.sub.T -value (molar excitation energy) of the solvatochromic compound is calculated and the water concentration is determined in accordance with the following equation:
