5种花梨木的红外光谱比较分析
Comparative analysis of five kinds of rosewood by infrared spectra
摘要
Abstract
In this paper we proposed the infrared spectrum analysis method in order to provide a new idea for identification of rosewood species.Five kinds of rosewood,Pterocarpus cambodianus,P.erinaceus,P.indicus,P.macarocarpus and P.pedatus were explored by FTIR,second derivative IR (SDIR) and two dimensional correlation infrared (2DIR) spectroscopy.The results showed that:1) The difference at 781 cm-1 in the FTIR spectrum could differentiate P.cambodianus and P.erinaceus from the other three kinds of rosewood.2) In the SDIR,an absorption peak at 1 179 cm-1 existed for P.erinaceus,that of P.macarocarpus occurred at 781 cm-1 ,P.pedatus had obvious absorption peaks at 1 351,1 299,1 147,1 131 and 938 cm-1,while P.indicus had no absorption peaks.3) In the 2DIR,the differences at 1 100,1 150 and 1 258 cm-1 could separate P.erinaceus from the other rosewood;the differences at 1 467 and 1 518 cm-1 could distinguish P.cambodianus,P.erinaceus and P.pedatus.Applying SDIR solely could not distinguish these rosewood completely,but a combination of FTIR,SDIR and 2DIR could identify all these five kinds of rosewood and provide a new way for non-destructive detection of rosewood.关键词
