Reduction of ultra-fine tungsten powder with tungsten (vi) oxide in a vertical tube reactor
(Institute of Metals and Technology, 2011)
The reduction of WO(3) with hydrogen in a vertical tube reactor is a new approach to the reduction of tungsten oxide compared to conventional procedures in a stationary layer. The advantage of this method is the intensive ...
Analytical methods for arsenic speciation analysis / Analitičke metode za analizu arsenovih jedinjenja
(Serbian Chemical Society, Belgrade, 2013)
Arsenic exists in the form of various chemical species differing in their physicochemical behaviour, toxicity, bioavailability and biotransformation. The determination of arsenic species is an important issue for environmental, ...
