GB/T 27652-2011 Methods of pretreatment for chemical analysis of preservative-treated wood
Basic Information
Scope
This standard specifies four methods for pretreatment before chemical analysis of preservative-treated wood: hydrogen peroxide-nitric acid digestion method, perchloric acid digestion method, microwave-nitric acid digestion method, and hydrogen peroxide-dilute sulfuric acid water bath method.
This standard is applicable to the pretreatment for analyzing the content of effective components such as arsenic, chromium, copper, and phosphate in preservative-treated wood. Among them, the microwave-nitric acid digestion method and the hydrogen peroxide-dilute sulfuric acid water bath method are suitable for pretreatment before analyzing the effective components of preservative-treated wood by atomic absorption spectrometers, inductively coupled plasma emission spectrometers, and atomic fluorescence spectrometers.
