摘要：

Factors influencing water samples stability and methods of preservation for analysis of inorganic compounds are presented. Preservation techniques referred in the literature are relatively limited. They are intended generally to retard biological action, hydrolysis of chemical compounds and complexes and reduce volatility of constituents. Acidification and refrigeration at 4-degrees-C are the techniques usually recommended. Guidelines proposed by International Organizations and mostly used by environmental laboratories are compared.
