【摘要】:十六烷基三甲基溴化銨通過靜電相互作用與羧甲基纖維素形成離子復(fù)合物膠束。電導(dǎo)率法測(cè)定離子復(fù)合物的最低聚集濃度為2.42×10-4mol/L。表面活性劑濃度達(dá)到聚電解質(zhì)等電點(diǎn)時(shí),復(fù)合物從溶液中析出沉淀。甲基橙的最大吸收波長發(fā)生藍(lán)移,證明在復(fù)合物溶液中存在膠束的疏水結(jié)構(gòu)。復(fù)合物粒徑在環(huán)糊精加入后減小,溶液透過率增加。
[Abstract]:Cetyltrimethylammonium bromide formed ion complex micelles by electrostatic interaction with carboxymethyl cellulose. The lowest aggregation concentration of ion complex determined by conductivity method is 2.42 脳 10 ~ (-4) mol / L. When the surfactant concentration reaches the polyelectrolyte isoelectric point, the complex precipitates from the solution. The blue shift of the maximum absorption wavelength of methyl orange indicates that there is a micellar hydrophobic structure in the complex solution. The particle size of the complex decreases with the addition of cyclodextrin and the transmittance of the solution increases.
