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 ...

Mercury monitoring for measuring mercury content in hair
Measurement of mercury content in hair is a convenient technique to estimate dietary exposure without having to handle tissues or bodily fluids. As the mercury present in hair is comprised of different mercury species, full speciation of the compounds is needed for complete understanding. Environment Canada published a technique where treating a basic digestion with Cd2+ in the presence of cysteine allowed analysis of inorganic mercury and total mercury using a Tekran 2600 System. Methyl mercury was then ...

Heat Exchangers Solutions for Pasteurisation of Sludge Sector
The heating and concentration of wastewater streams and sludge are an essential process in many industries, not just water treatment. Pasteurisation of sewage sludge and digestate (biosolids) to make them biologically safe for further processing, disposal or use is a key process. Two common issues with some other sludge pasteurisation systems are their inherent inefficiency and fouling of the heat exchanger tubes due to the nature of the sludge or wastewater material. HRS Heat Exchangers overcomes the fouling ...

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 ...

Flame Photometer for Measurement of Na, K and Ca in Plant Extracts
The most important ions which naturally occur in plant tissues are sodium, potassium, calcium, magnesium, nitrate, sulphate and phosphate. A sample of 5 g of oven-dried plant material contains on average, 25 mg calcium, 9 mg magnesium, 80 mg potassium and 3 mg sodium. The recommended method for the measurement of calcium is to precipitate the calcium as an oxalate, the precipitate is then dissolved and measurement taken from the resulting solution. Sodium and potassium may be measured directly following an ashing ...
