Mercury determination in natural, surface, sea, drinking, bottled, mineral, and waste water by cvaas
Introduction Mercury determination in natural, drinking, and waste waters is one of the most popular analyses used for environment pollution and sanitary control. Background concentrations of mercury in natural water are within several ng/l. Maximum national permissible levels for mercury in water lie in the range of 0.16–6 µg/l. For example, the following limits for mercury in drinking water are set, µg/l: 0.5 – Japan, Russia; 1 – Argentina, Australia, Brazil, China, EC; 2 ...

Rapid analysis of total mercury in waste waters and process waters with elevated mercury content using direct pyrolysis technique
Introduction A conventional standard method of total mercury det ermination in water using atomic absorption spectrometry (AAS) involves preliminary sample digestion that ta kes from 30 minutes to 8 hours depending on the digestion conditions. The use of a mercury analyzer RA-915M/RA-915+ with Zeeman background correction in combination with PYRO-915+ pyrolysis attachment provides direct dete rmination of mercury in process and waste waters contaminated with mercury without digesti on or any other sample ...

Determination of total mercury content in blood by cvaas
INTRODUCTION Blood is one of the most complex substances for determination of the Hg content. At the same time, blood is the most important diagnostic medium used for monitoring the effect of Hg vapor on the human organism. In almost all the countries, personnel of mercury-involving production facilities are regularly examined for the Hg content in blood, which should not exceed 20–50 µg/l, whereas in the case of a person unexposed to mercury vapor the blood normally contains 1–3 µg/l of ...

Determination of the mercury concentration in naphtha
Introduction The mercury concentration in crude oil and petroleum products can vary in a wide range of less than 0.1 ppb to dozens ppm. Direct mercury determination in crude oil and petroleum products at the range above 5 ppb is covered by ASTM D7622-10(2015) "Standard test method for total mercury in crude oil using combustion and direct cold vapor atomic absorption method with Zeeman background correction". Mercury determination in naphtha and light petroleum products (condensate, gasoline and diesel fuel) at a ...
