| 摘 要： | 在0.2 mol/L H_2SO_4介质中,磺胺二甲嘧啶(SM_2)和KMnO_4在加热条件下发生氧化还原反应生成MnO_2微粒,导致共振瑞利散射(RRS)增强,并产生新的散射峰.其最大散射波长位于595 nm附近,散射强度在一定范围内与SM_2的浓度成正比,据此建立了测定SM_2的共振瑞利散射(RRS)新方法.本方法具有较高的灵敏度,检出限为8.6 ng/mL.实验优化了测定条件.考察了共存物质的影响,表明方法具有良好的选择性,用于片剂中SM_2的测定,结果满意.Abstract：In 0.20 mol/L H_2SO_4 medium, a redox reaction took place between sulfadimidine (SM_2) and po-tassium permanganate to form MnO_2 particles by heating.As a result, new spectra of resonance rayleigh scattering appeared and their intensities were enhanced greatly.The maximum peak of RRS was located at approximately 595 nm, and the scattering intensities were proportional to the concentration of SM_2.Based on these results, a new method for the determination of SM_2 was established.The detection limit (3σ) was 8.6 ng/mL.The effects of coexistent substances were tested, and the results demonstrated that this meth-od had good selectivity.It has been applied to the determination of SM_2 in tablets with satisfactory results.
