A technical note on the limitations of atomic absorption spectrophotometric analysis of copper/chrome/arsenic solutions according to BS 4072 (1974) and BS 5666: Part 3 (1979)
1988 - IRG/WP 2320
British Standards BS 4072 (1974) and BS 5666: Part 3 (1979) detail an atomic absorption spectrophotometric method for the quantitative determination of copper, chrome and arsenic in both preservative solutions and treated timber. Use of this technique during a research programme at Aberdeen has highlighted some…
