请问反相微乳中的”w=7.4 microemulsion“w=7.4是什么意思
|
|
A w¼7.4 microemulsion was prepared by the addition of 0.2ml of a 25 mg ml1 L1-Na4 aqueous solution (obtained by deprotonation with 3M NaOH) and 0.2 ml of a 100 mg ml1 Zn(NO3)2 aqueous solution to separate 5ml aliquots of a 0.3M Triton X-100/1.5 M 1-hexanol in cyclohexane mixture while vigorously stirring at room temperature. Twenty microlitres of DOPA solution (200 mg ml1 in CHCl3) was added to the complex solution and the stirring was continued for 15 min until a clear solution formed. The two microemulsions were combined and the resultant 10 ml microemulsion with w¼7.4 was stirred for 30 min. After the addition of 20 ml ethanol, 1 was obtained by centrifugation at 12,000 r.p.m. 这是林文彬的一篇论文中的制备NCP的方法，请问w=7.4是什么意思？ |
