Description of BS 5666-5:1986 1986

This Part of BS 5666 describes procedures for the determination of zinc naphthenate, expressed as zinc, in preservative solutions and in treated timber. Two methods are described: an atomic absorption spectrophotometric method and a colorimetric method.

Both methods have been found suitable for the determination of zinc naphthenate in the presence of tributyltin oxide, pentachlorophenol, o-phenylphenol, monochloronaphthalene, polychloronaphthalene, gamma-HCH (gamma-BHC)1), dieldrin1), copper naphthenate, water-repellent waxes and resins.

The procedures described have been primarily designed for the analysis of preservative formulations complying with BS 5707-1. For samples of other compositions it may be necessary to make adjustments in the quantities taken for analysis.

The timber sample for analysis may be in the form of sawdust, wood flour or thin sections.

NOTE The titles of the publications referred to in this standard are listed on the inside back cover.

CAUTION. Attention is drawn to the general safety precautions mentioned in clause 4 of BS 5666-1:1978.



Two methods: atomic absorption spectrophotometry and colorimetry using dithizone.
