METHOD FOR THE QUANTITATIVE ANALYSIS OF COPPER NAPTHENATE PRESERVATIVE FORMULATIONS AND TREATED TIMBER
This Malaysian Standard details procedures for the determination of copper naphthenate, expressed as the amount of copper present, in preservatives and in treated timber containing this preservative.
The methods have been found suitable for the determination of copper in the presence of tributyltin oxide, pentachlorophenol, o-phenylphenol, monochloronaphthalene, polych)oronaphthalene, ‘y -HCH, dieldrin. zinc naphthenate, potassium salts and sodium salts. The wood sample may be in the form of sawdust, wood flour, or thin sections.
The procedure for the analysis of preservatives has been primarily designed for solutions complying with the requirements of MS 878~.For samples of other compositions it may be necessary to make adjustments so that the solutions are within the analytical range and in the AAS determination, sample solution and standard solution have similar solution matrix. It is difficult to make recommendations as to the quantity of sample to be taken in the case of treated
