Affinity Cibacron Blue 3GA (CB) dye in aqueous phase was directly transferred to the reversed micelles due to electrostatic interaction between anionic CB and cationic cetyltrimethylammonium bromide (CTAB). The bovine serum albumin (BSA) transfer to the reverse micelles increases significantly in a wide range of pH by the addition of a small amount of CB ( approximately 1.0-7.0% of the total su...

A cloud point extraction (CPE) process was described for the separation and spectrophotometric analysis of Fe(III) in different water samples blood as chelating agent. The complexation reaction between Zincon elaborated at pH 5.0 using acetate buffer complex quantitatively recovered a mixed micelle system composed cethyltri methyl ammonium bromide (CTAB) Triton X-114. This carried out room temp...

Isolation of RNA from recalcitrant tree tissues has been problematic due to large amounts of secondary metabolites and interfering compounds in their cells. We have developed an efficient RNA extraction method, which yielded high-quality RNA preparations from tissues of the lychee tree. The method reported here utilized EDTA, LSS, and CTAB to successfully inhibit RNase activities. It was found ...

Control of EOF in microfluidic devices is essential in applications such as protein/DNA sizing and high-throughput drug screening. With the growing popularity of poly(methyl methacrylate) (PMMA) as the substrate for polymeric-based microfludics, it is important to understand the effect of surfactants on EOF in these devices. In this article, we present an extensive investigation exploring chang...

This study developed a coagulation-flotation process for microalgae Chlorella sp. XJ-445 harvesting, which was composed of algal surface modification by combined use of Al3+ and cetyltrimethylammonium bromide (CTAB) and followed dispersed bubble flotation. Dissolved organic matter (DOM) in the medium was firstly characterized and mainly consisted of hydrophilic low molecular weight molecules. T...

The vertical depth distribution of individual additive components (cetyltrimethylammonium bromide (CTAB) and deuterated pentaethylene glycol monododecyl ether (d25-C12E5) and deuterated glycerol (d-glycerol) in PVA film have been isolated and explored by ion beam analysis techniques and neutron reflectometry. The additives display an unexpectedly rich variety of surface and interfacial behaviou...

In this paper, ionic liquid (IL)-coated magnetic Fe(3)O(4) nanoparticles (NPs) as an adsorbent of mixed hemimicelles solid-phase extraction (SPE) was investigated for the preconcentration of polycyclic aromatic hydrocarbons (PAHs) from environmental samples. Due to the high surface area and excellent adsorption capacity of the Fe(3)O(4) NPs after modification with ILs, satisfactory extraction r...

A cloud-point extraction process using micelle of the cationic surfactant CTAB to extract Fe3+and Pb2+ from aqueous solutions was investigated. The method is based on the color reaction of Fe3+and Pb2+ with bromopyrogallol red at pH 5.0 and micelle-mediated extraction of the complex. The optimal extraction and reaction conditions (e.g., surfactant concentration, reagent concentration and effect...

A simple and sensitive solid-phase extraction method for separation and preconcentration of trace amount of four nonsteroidal anti-inflammatory drugs (naproxen, indomethacin, diclofenac, and ibuprofen) using Fe3O4 magnetic nanoparticles modified with cetyltrimethylammonium bromide has been developed. For this purpose, the surface of MNPs was modified with cetyltrimethylammonium bromide (CTAB) a...

DNA fingerprinting singly or in combination with phytochemical analysis is ideal for quality control of crude plant-based drugs. However, when the source material is tannin rich stem bark, extraction of DNA by conventional methods becomes challenging. In such cases, phytochemical profiling serves as very useful tool for its identification. The work herein described a method for simultaneous DNA...
