Abstract:
A kind of plywood containing some chromium and arsenic elements for container floor was prepared by optimizing the preparing process and adding method of chemical reagents based on wood dry mass constant. The prepared sample was treated and the contents of chromium and arsenic elements were tested with atomic absorption and atomic fluorescence spectrophotometers, respectively. Test results showed that the chemical reagents in the plywood were distributed homogeneously, and resistance leach ability was very well. The methods of detection chrome and arsenic had the advantages of quick and simple, as well as the sensitivity of the instrument could meet the needs for daily inspection work.
