摘　　要：对生化试剂—甲苯胺蓝（ Ｔｏｌｕｉｄｉｎｅ Ｂｌｕｅ ． Ｔ Ｂ） 水溶液的吸收光谱进行了研究．测定出在波长为６６５ ｎｍ 和６１０ ｎｍ 处有两个最大吸收峰，证明 Ｔ Ｂ 在水溶液中存在着单体与双分子聚集体的解离平衡．其二聚体的含量与溶液的浓度成正比．并用差示光谱预测了甲苯胺蓝双分子聚合体的分子构型．通过在 Ｔ Ｂ 溶液中添加阴离子表面活性剂研究了其浓度对体系聚合状态的影响，得出 ＴThe absorption spectra of biochemical agent Topudine Blue (TB)in aqueous solution has been studied in this paper.Two maximum absorptic peaks have been found at 665 nm and 610 nm,which suggest that there is a equillibrium state between monomer and dimer TB.The portion of dimer is proportional to the concentrions of TB.The molecedar structure of dimmer TB.has been determined on the difference spectrum between TB monomer and dimer.The effect of the concentration of surfactants on the solution states has also been studied.
