Use

1. Cupferron is used for quantitative analysis for aluminum, zinc, copper, iron, gallium, mercury, manganese, niobium, tin, tantalum, thorium, titanium, vanadium, zirconium and other elements 2. It is used as polymerization inhibitor, due to unique polymerization inhibition characteristics of cupferron, also the amount is small, can be used as an alternative of phenol polymerization inhibitor BHT, which is current largely applicated. 3. Cupferron is used for colorimetric determination for the weight of aluminum, bismuth, copper, iron, mercury, zinc, manganese, niobium, gallium, tantalum, thorium, titanium, vanadium, tin and other elements of. It is used for quantitative determination of iron in the strong acid solution, quantitative analysis of vanadate, separation of copper and iron together with the other metals, as a masking agent for measuring rare earths.
