Automated continuous monitoring of inorganic and total mercury in wastewater and other waters by flow-injection analysis and cold-vapour atomic absorption spectrometry
An automated continuous monitoring system for the determination of inorganic and total mercury by flow-injection analysis followed by cold-vapour atomic absorption spectrometry is described. The method uses a typical flow-injection manifold where digestion and reduction of the injected sample takes place. Mercury is removed by aeration from the flowing stream in a specially designed air-liquid ...
متن کاملoptimization of a novel setup for an on-line study of elemental mercury adsorption by cold-vapor atomic absorption spectrometry
background: the objective of this work was developing a simple and stable time-based on-line setup for assessing the potential of mercury (hg) vapor adsorption of the commercial sorbents used in air sampling and control operation followed by cold vapor atomic absorption spectrometry (cvaas). methods: a special designed separation chamber was used where reduction of the injected hg (ii) solution...
متن کاملModified determination of total and inorganic mercury in urine by cold vapor atomic absorption sectrometry.
In this procedure a single-beam spectrophotometer is used without background correction. By the method of Magos [Analyst (London) 96, 847 (1971)] mercury in undigested urine is complexed to L-cysteine in acid solution. At high pH and in the presence of stannous ions, mercury ions are reduced to elemental mercury. The mercury vapor is partitioned above the reagent solution in a specially designe...
متن کاملDetermination of mercury in the urine by atomic absorption spectrometry - cold vapor technique
Urine is a liquid waste product of the body. Substances that are ingested and fail to be apsorbed are excreted, solid waste through the intestines, the urine through the kidney and ureter and another fluid from the body through perspiration. Determination of mercury content of urine is not included in routine examinations, but mercury can be present in urine at concentrations that could have se...
