本文提出间三联苯和对三联苯的二阶导数-固体基质室温燐光法(d~2SS-RTP)。本法在λ_(2d)=288nm,用448nm处正峰和460nm处负峰的峰峰高度值定量测定间三联苯,对三联苯不干扰测定.线性范围0.46～46ng.检出限为0.1ng/斑点.对三联苯用526nm处正峰和548nm处负峰的峰峰高度值测定.间三联苯不干扰.线性范围0.46～46ng.检出限0.07ng/斑点.
In this paper, the second derivative of m-terphenyl and p-terphenyl is described - solid substrate room temperature cofractometry (d ~ 2SS-RTP). This method was used to quantitatively determine m-terphenyl at λ2d = 288nm with the peak heights of the negative and positive peaks at 448nm and 460nm.The results showed that the method did not interfere with the determination of terphenyl.The linear range was 0.46 ~ 46ng.The detection limit was 0.1ng / Spots. The terphenyls were measured at the peak heights of the positive peak at 526 nm and the negative peak at 548 nm. The m-terphenyl did not interfere. The linear range was 0.46 to 46 ng. The detection limit was 0.07 ng / spot.
