摘　　要：研究了 1 -萘胺 ( NNA)的无保护流体室温磷光 ( NP- RTP)测定条件及共存物影响。在以 KI为重原子微扰剂、Na2 SO3为除氧剂及 λex/λem=31 7/5 1 8nm的最佳组合条件下 ,测定 NNA的线性范围及检出限分别为 1 .4× 1 0 - 7～ 2 .5× 1 0 - 5mol/L及1 .2× 1 0 - 8mol/L。方法已用于江水及井水样品中 NNA的测定 ,回收率 98.2 %～1 0 1 .9%,相对标准偏差 1 .2 %～ 1 .3%。A method has been studied for the determination of 1 naphthylamine in natural water by non protected fluid room temperature phosphorescence (NP RTP). Using KI as a heavy atom perturber and Na 2SO 3 as a deoxygenator, at λ ex / λ em =317/518 nm, the linear dynamic range, the detection limit, the recovery and RSD of the proposed method were 1.4×10 -7 ～2.5×10 -5 mol/L, 1.2×10 -8 mol/L, 98.2%～101.9% and 1.2～1.3%, respectively.
