Dyed Wastewater Treatment via Ionic Liquids

Currently, Waste water generated by the textile industry is one of the main issues that contribute
to the water pollution. This is due to the fact that, this type of industry consumes large amount of
process water and chemicals and therefore, produces high volume of highly polluted discharged
water. Due to its dreadful impacts towards the environment and aquatic livings, various
researches have been conducted to treat these effluents. Presently, various methods have been
established by the researchers such as the biological, chemical and physical treatment.
Associated with that, removal of dyes via ionic liquids is one of the techniques, which is still not
widely applied by industries but it has been discovered to be able to treat dyed wastewaters.
Since the research of ionic liquid for this application is still at surface level, the major concerns
such as process efficiency in terms of economic and residual water quality and at the same time,
to improve the amount of dye removal with minimal usage of ionic liquids. In this research
project, experiments have to be carried out by varying few parameters, which are concentration
of dyes in waste water, pH, temperature and effect of types of ionic liquids. Results from the
parameters tested will be analyzed quantitatively in percentage of dye removed per unit mass of
ionic liquids with the help of UV-Vis spectrophotometer.
