Washing is one of the common technologies in the chlorinated organic pollution site repair, surfactant adding would help washing more chlorinated organics pollution, but it also can be dissolved in eluent with the chlorinated organic together, and increase the difficulty of the eluent treatment. In this text, three surfactants, anionic surfactant (sodium dodecyl benzene sulfonate, SDBS), cation...

A polyelectrolyte ionomer complex (PIC) composed of cationic and anionic polymers was developed for nanomedical applications. Here, a poly(ethylene glycol)-poly(lactic acid)-poly(ethylene imine) triblock copolymer (PEG-PLA-PEI) and a poly(aspartic acid) (P[Asp]) homopolymer were synthesized. These polyelectrolytes formed stable aggregates through electrostatic interactions between the cationic ...

Nanoparticles (NPs) are in clinical use or under development for therapeutic imaging and drug delivery. However, relatively little information exists concerning the uptake and transport of NPs across human colon cell layers, or their potential to invade three-dimensional models of human colon cells that better mimic the tissue structures of normal and tumoral colon. In order to gain such inform...

Mining activities are followed by mineral processing and wet beneficiation methods which generate a significant amount of tailings. Slime fractions discharged to the tailing ponds with associated process water this causes storage disposal difficulties creates severe environmental problems. Therefore, dewatering these tailings is necessary for both economic aspects. In study, flocculation behavi...

In this study, microemulsions of the chiral surfactant polysodium N-undecenoyl-D-valinate (poly-D-SUV) was utilized for enantiomeric separation by investigating two approaches using polymeric chiral surfactant in microemulsion electrokinetic chromatography (MEEKC). In the first approach, poly-D-SUV was used as an emulsifier surfactant along with 1-butanol and n-heptane. Enantioseparation of ani...

The present work was conducted on the effect of surfactant on the dissolution rate of ibuprofen tablets. The cationic (Cetyl Trimethyl bromide) and anionic (Sodium dodecyl sulphate) surfactant present in the dissolution media have remarkable effect on the dissolution rate of Ibuprofen. Maximum dissolution was obtained in the presence of anionic surfactant (Sodium dodecyl sulphate) at 0.5% conce...
