ABSTRACT

Pollution abatement of wastewaters coming from textile industry still remains a major
concern for environmental risk, representing serious threats both for environment and
human health. Among the modern techniques the microemulsification appears to be one
of the most promising methods, being used in various processes such as separation,
concentration, extraction, etc. This paper presents the application of two microemulsion
systems: water/Brij 30/iso-propanol/pine oil and water/Brij 30/ethyl acetate in removal
of crystal violet dye as typical dye discharged from textile industry. The efficiency of
color removal has been monitored by using CIE L*a*b* trichromatic space, and color
difference ΔE*ab. The efficiency of the dye removal was greater than 95%, the results
obtained being in compliance with standard regulations in force.
