This paper deals with a thermo-responsive poly(N-isopropylacrylamide) (NIPA) gel containing a polymeric surfactant poly(2-(methacryloyloxyl)decylphosphate) (PMDP) which shows rapid volume change above phase transition temperature at ca. 34 degrees C. Based on the measurements of dye-solubilization, it was suggested that intra-molecular micelles of the polymeric surfactant PMDP are inside NIPA gel-network. It is concluded that the intra-molecular micelles of polymeric surfactant involving NIPA chains may play crucial role in the rapid collapse of the NIPA-PMDP gel at the phase transition temperature. 相似文献

The membrane-based grey water treatment for grey water reuse and surfactant recovery is presented in this research paper. Grey water from washing machine discharges having turbidity and used surfactant was processed through the polymeric ultrafiltration (UF) membrane to remove the turbidity. The UF treated grey water is further purified by reverse osmosis (RO) membrane for surfactant recovery and water reuse. The surfactant trapped inside the RO spiral wound membrane module is recovered through various membrane physical regeneration techniques such as backwashing, simultaneous backwash–back-flush and ozone back-flush. Among this, backwash–back-flush is found to be effective process for surfactant recovery. The methodology for optimising surfactant recovery is captured by studying effect of various operating parameters such as feed detergent concentration, backwash pressure, backwash temperature and back-flush flow rate. By implementing optimal process conditions, the integrated UF and RO membrane process is able to produce 300 L of reusable pure water and 80 L of concentrated detergent solution and 20 L of turbid water while treating 400 L of grey water discharges. Maximum surfactant recovery of 82% is obtained while treating grey water which consists of 720 ppm of total dissolved solids (detergent) and 45 ppm of surfactant. The extent of UF and RO membrane fouling is determined by measuring the pure water flux before and after the grey water treatment. The membrane performance is found to be stable when membrane is regenerated by backwash–back-flush technique for RO and gravity backwash for UF membrane. 相似文献

To study the adhesion of the anionic surfactant sodium dodecyl sulfate (SDS) to various materials, a schematic molecular model of SDS was used which optimally correlates with its critical micelle concentration (c.m.c.) values under various conditions. Using the surface tension components and parameters of (a) the SDS apolar and polar moieties and (b) the polymeric surfaces of cellulose and nylon, the energy of adhesion of SDS to these polymeric surfaces as well as to a typical low-energy material (greasy dirt) in the guise of hexadecane was determined. It could be quantitatively shown (using a surface-thermodynamic approach) that SDS, in water, adheres more strongly to the low-energy (greasy dirt) compounds than to the polymeric materials. The c.m.c. of SDS was derived directly from the surface tension components and parameters of its apolar and polar moieties, and the ζ potential of its polar heads. The c.m.c. values obtained using this model correlate well with the published c.m.c. values obtained experimentally at different ionic strengths. 相似文献

AKD专用高分子表面活性剂的性能研究 总被引:2,自引:0,他引:2
设计并合成了一种高分子表面活性剂,用FTIR、DSC、GPC分析手段研究了高分子表面活性剂的分子结构,并对其表面张力进行了测定。测试结果显示,4种单体都参与了共聚反应,无均聚物存在,高分子表面活性剂的重均分子量为58 536,数均分子量为16 812,多分散性系数为3.48,说明相对分子质量(简称分子量)的分散程度较小。温度为25℃时,高分子表面活性剂的CMC为0.8 mmol/L,γCMC为50.1 mN/m。当m(高分子表面活性剂)/m(烯酮二聚体)=0.23时,可制备出稳定的烯酮二聚体(AKD)乳液,且该AKD乳液质量占绝干浆质量的0.13%时,浆内施胶度可达200 s以上。用马尔文纳米粒度及Zeta电位分析仪测定出AKD乳液的平均粒径为574.4 nm,Zeta电位为11.16 mV。通过TEM观察,AKD乳胶粒子在高分子表面活性剂的包裹下呈核壳结构,并且形成水包油乳液。该高分子表面活性剂具有良好的表面活性与应用潜力。 相似文献
