3. ftnalytical methods General properties are measured by standard instrumental methods: conductivity; pD; gamma scan and turbidity. S. analysis. , specially in the case of cations lithium, sodium, magnesium, iron, copper and other metals. Ionic chromatography is specially recommended for anionic species: nitrate, carbonate, silicate, chloride and fluoride. The most common method for organic compounds determinations is visible-uv spectrometry. Special assemblies neasure dissolved gases on line, like oxygen and hydrogen.
