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.
