Abstract
Surfactants are characterized as having amphipathic structures. The solubilization of water insoluble products in water solvent-surfactant mixtures plays a significant role in numerous fields of industries such as polymer industry, enhanced oil recovery, emulsion, drug distribution, textile staining and detergency. Surface active agents molecules tend to aggregate themselves into structures named as micelles. The formation of these micelles is accountable for the hydrophobic substances that are solubilized in surfactant-water system. The present review focuses to study the effect of various parameters like pH, temperature, additive effect, surfactant structure and its concentration on the solubilizing power of surfactant molecules resulting in the exclusion of organic coloring agents/dyes which may serve as contaminants or pollutants. In addition to solubilization phenomena, in the present study foam formation more specifically ion flotation has been discussed to understand the dye-surfactant interactions resulting in the removal of dyes/colored substances.
