Analytical Chemistry of Minerals
Cupferron reacts with many cations, forming insoluble compounds. As regards
the analysis of minerals and rocks, of practical interest is the use of cupferron to
precipitate iron, vanadium, zirconium, titanium, tin, niobium, tantalum,
molybdenum ...
Anatoliĭ Ivanovich Samchuk, Anatoliĭ Terentʹevich Pilipenko, 1987
Subsequent, more detailed studies (Kihlman, 1959b) showed that the effect of
cupferron is strongly influenced by the pH and temperature of the treatment
solution. The effect was enhanced by high temperature and low pH. Since
cupferron is ...

Novel NO Donor Compounds: orth and para Substituted Cupferron Derivatives
Cupferron is an N-NO donor of the /V-nitroso- jV-oxyarylamine family. It is widely
used as a metal chelator and a polymerization inhibitor [34]. Over the past few ...

CRC Handbook of Organic Analytical Reagents, Second Edition
Since most of the metal Cupferrates are not highly colored, Cupferron is not of
practical importance as photometric reagent for the determination of trace of
metals. Purification and Purity of Reagent Crude material may be purified by ...

Reagents in Mineral Technology
The adsorption density of cupferron on chalcopyrite was reported to be higher
than that of xanthate, yet flotation with cupferron was not quantitative even at 6.5
x 10"4 M (0.1 g/1) and in the presence of 0.1 g/1 fuel oil. Xanthate flotation at this
...

The Journal of Industrial and Engineering Chemistry
Rodeja2 in another paper claims that cupferron does not quantitatively
precipitate vanadic salts in dilute acid solutions but does precipitate vanadyl salts
. Turner8 in an attempt to separate vanadium from uranium found that a
metavanadate ...

The Radiochemistry of Plutonium
Cupferron N-nitrosophenylhydroxylamine or cupferron has been used as a
precipitating agent for many metal ions for many years, and the solubility of these
complexes in non-polar solvents such as chloroform was recognized at an early
date.

6th Annual Report on Carcinogens (1991)
USE Cupferron is an analytical reagent that is used to separate tin from zinc, and
copper and iron from other metals. In analytical laboratories, cupferron is a
reagent used for quantitative determination of vanadates and titanium and ...
