Polymeric Chemisorbents for Organic Acid Recovery from Aqueous Solution
… successfully chemisorb succinic acid from dilute aqueous solution with efficiencies that are competitive to polymeric chemisorbents that are reported in literature. Novel recovery methods that are more environmentally conscious than traditional methods are tested, such as the use of saturated …

Multinuclear NMR Studies of Gallium Complexes in Aqueous Solution.
… of gallium localization in tumor cells, the aqueous chemistry of gallium(III) was investigated by nuclear magnetic resonance (NMR) spectroscopy. Specifically, these studies include: characterization under various experimental conditions (pH, concentration, temperature etc.) of gallium citrate …

Design and characterization of multicompartment micelles in aqueous solution
… of amphiphilic diblock copolymers in solution. The dissolution of these block copolymers in a solvent selective for one block results mostly in the formation of micelles. The micellar structure of diblock copolymers is inherently limited to a homogeneous core surrounded by a corona, …

Physico-chemical studies of block copolymers in aqueous solution
The dilute aqueous solution behaviour of oxyethylene/oxypropylene copolymers has been investigated as a function of temperature (275-370K), copolymer concentration (0.1-5% w/v) and copolymer composition [polyoxypropylene (POP) and polyoxyethylene (POE) homopolymers (750-4000gmol-1 ) and diblock …

Predispersed solvent extraction of copper from dilute aqueous solution
… used to extract copper ions from dilute acidic aqueous solution. POSE is based on the principle that there is no need to comminute both phases. All that is necessary is to comminute the solvent phase prior to contacting it with the feed. This is done by converting the solvent into aphrons. which …

The extraction of analytes from aqueous solution using supercritical fluids
… Supercritical fluid extraction of analytes from aqueous solution has not received much attention. The design of a system which allows for the extraction of analytes from aqueous solution has been explored in this thesis. Several related areas (injection techniques for supercritical fluid …

The adsorptive properties of oligomeric, non-ionic surfactants from aqueous solution
… (of the alkyl polyoxyethylene type) from aqueous solution onto mineral oxide surfaces. The oligomeric distributions of the surfactants were characterised using the HPLC technique. Two gradients were used: a normal phase gradient was used to study the surfactants from non-aqueous solution; …

REMOVAL OF EMERGING CONTAMINANTS FROM AQUEOUS SOLUTION BY OZONE -BASED PROCESSES
The presence of emerging contaminants (ECs) in water and wastewater systems has become a subject of significant concern worldwide. These emerging contaminants are complex organic molecules which potentially affect human health and environment. Conventional wastewater treatment plants are unable to …
