Laboratory use specifications and test methods GB/T 6682-2008 Analysis
3 PRINCIPLE OF THE METHOD
Method A. Weigh a certain amount of paint samples in the beaker to evaporate the solvent to remove organics which burned at 600 ℃ get dry
Gray, then adding an acid to digest, after dilution dissolved, insolubles were removed by filtration, the filtrate was electrolysis to precipitate copper attached to the platinum electrode.
Calculate the mass percentage of copper deposited to obtain the number of the total content of copper, which can be in terms of the content of the original copper compound.
Method B. antifouling paint dry sample with a suitable acid solution was sealed microwave digestion, the rush acid, constant volume after treatment, using flame atomic absorption
Spectroscopy or income to meet current and effective method for testing the accuracy of the analysis of each sample of the total copper content can be obtained in the antifouling paint
The percentage of the total content of copper or copper quality.
4 Reagents
Unless otherwise indicated, the reagents used in the analysis were of analytical grade water to comply with GB/T 6882-2008 requirements for secondary water. The standard
Reagents quasi involved are as follows.
4.1 Method A
The reagents used.
a) nitric acid, ρ about 1.42g/mL;
b) perchloric acid, the mass fraction of from 69% to 72%;
c) an alcohol or acetone;
d) ammonium sulfate.
