Formulation is an ancient concept, although the word has been used only recently. The first
formulations made our civilization advance by inventing bronze, steel, and gunpowder; then …

Four different oxidation process, namely direct photolysis (DP) and three advanced
oxidation processes (heterogeneous photocatalysis–HP, eletrochemical oxidation–EO and …

This work introduces a simplified methodology for measuring the characteristic curvature
(Cc) of commercial alkyl ethoxylate nonionic surfactants using carefully selected reference …

In this work the photoelectrooxidation (PEO) was applied in the treatment of a solution
containing nonylphenol ethoxylate surfactant (NP 4 EO). The use of different lamps (125 and …

Proteins (bovine serum albumin (BSA), α‐chymotrypsin, cytochrome c, and lysozyme) were
extracted from 0.5 to 2.0 g L− 1 aqueous solution by adding an equal volume of isooctane …

The partitioning of corrosion inhibitor (CI) products is a measure of their potential to protect
oilfield pipelines. In this paper the hydrophilic–lipophilic deviation (HLD) model is first used …

Efforts to remove the dense nonaqueous phase liquids (DNAPLs) in subsurface by
mobilizing them face with risks of driving the contaminants deeper into aquifer zones. This …

The surfactant characteristic parameter (SCP) is numerically related to its amphiphilic
interactions with oil and water phases. Basic ideas have resulted in the energy balance …

High resolution 1H and 13C NMR were used to characterise complex mixtures of industrial
polyoxyethylated surfactants of the CiEj series. A progressive methodology was applied to …

Os poluentes orgânicos emergentes (POE) são compostos químicos presentes numa
variedade de produtos comerciais como medicamentos, produtos de higiene, agrotóxicos …
