摘要
运用荧光光谱对苏木素-明胶的作用进行了研究,同时进一步研究了苏木素-阳离子表面活性剂十六烷基三甲基溴化铵(CTAB)-明胶的相互作用。研究表明苏木素-CTAB对明胶内源荧光的猝灭机制属于静态猝灭,猝灭常数Ksv=2.93×103(mol.L-1)-1;明胶与苏木素反应的结合常数KLB=7.38×104mol.L-1,结合位点n=1.395,加入CTAB后其结合常数KLB=5.69×106mol.L-1,结合位点n=2.056。这为苏木素和表面活性剂在皮革染色工业中的应用在理论上作了一定的探索。
The binding interation between hematoxiline and gelatin was studied with Fluorecence spectrum. The reaction mechanism of hematoxiline and cationic surfactant（CTAB） with gelation was also investigated. The results show that the quenching mechanism of hematoxiline and cationic surfactant（CTAB） with gelation is a static quenching procedure, the quenching constant KLB is 2. 93 × 10^3 （mol·L^-1）^-1 Then gelation can be connected with hematoxiline much better, the equilibrium constant KLBis 7.38 10^4 mol·L^-1 , and the combining sites n is 1. 395. But adding CTAB after the above reacting system the equilibrium constant KLB is 5. 69 10^6mol·L^-1 , and the combining sites n is 2.056. All above research had a exploratory in theory for hematoxiline and surfactant＇s application in leather dyed industry.
