Simple, rapid method for determining trace mercury in fish via neutron activation analysis

Submicrogram level determination of mercury in seeds, grains, and food products by cold-vapor atomic absorption spectrometry

“…Various methods have been employed for the determination of mercury in atmospheric, aquatic, and biological samples (Basely, 1971;Pillay et al, 1971;Rottschafer et al, 1971;Moffitt and Kupel, 1970;Kalb, 1970;Fishman, 1970;Mayer, 1970;Cranston and Buckley, 1972;Lindstedt, 1970;Lindstedt and Skare, 1971; Malaiyandi and Barrette, 1970;Hatch and Ott, 1968;Suzuki et al, 1970Suzuki et al, , 1971Sjostrand, 1964;Sandell, 1959; Nobel, 1961;Rathje, 1969 Bucknell, 1951). The colorimetric dithizone method (Basely, 1971;Mayer, 1970;Sandell, 1959;Nobel, 1961;Bucknell, 1951), which is considered to be the classical analytical procedure for the determination of trace amounts of mercury, is not very sensitive and is subject to a large number of chemical interferences.…”

The method of neutron activation analysis (Pillay et al, 1971;Rottschafer et al, 1971;Sjostrand, 1964) has been employed for a variety of samples, but this method is expensive. Recently, several methods involving the use of cold-vapor atomic absorption spectrometry for mercury determinations have been published (Moffitt and Kupel, 1970;Kalb, 1970;Fishman, 1970;Cranston and Buckley, 1972;Lindstedt, 1970;Lindstedt and Skare, 1971;Malaiyandi and Barrette, 1970;Hatch and Ott, 1968;Suzuki et al, 1970Suzuki et al, , 1971; Rathje, 1969;Gage and Watten, 1970).…”

Determination of Ultratrace Levels of Mercury in Biological Samples Using a Single, Multi-Matrix Radiochemical Neutron Activation Analysis Technique

“…Commonly employed RNAA techniques for the analysis of biological samples involve complicated separation procedures and specialized equipment [22][23][24]. Rottschafer et al [25] employed a simplified RNAA technique involving a nitric acid digestion and retention of l97 HgCl4~ on anion exchange resin for the analysis of Hg in fish tissue. However, this procedure did not eliminate the Compton interference from 82 Br or correct for possible interference from the X-ray photopeak of 198 Au; both of which are retained by the resin.…”
