Automated method for the determination of total and inorganic mercury in water and wastewater samples
An automated method for the determination of total as well as inorganic and organic mercury by the cold vapor method is given. The method is suitable for the analysis of samples in a variety of environmental water matrices. A detection limit of 0.05 myg/l.is obtained by the use of a highly sensitive spectrometer. The method is suitable for the analysis of samples with mercury concentrations in the range 0.05-6 myg/l. and a COD of less than 700 mg/l. The use of potassium persulfate, potassium permanganate, potassium dichromate, and mixtures of these salts as oxidizing agents for the digestion step is discussed, and a study of sample preservation is given. Twenty samples and/or standards per hour, can be analyzed using this method.
