Separation of Crystal Violet Dye from Wastewaters by Using Supported Liquid Membrane Technology

The current study enumerates the use of supported liquid membrane (SLM) technology to remove and recover crystal violet dye from wastewaters. management textile industry waste effluents is one main concerns environmental health experts due having excessive concentrations dyes resistance biodegradation. Liquid membranes offer an affordable green method for selective removal aqueous solutions. To create a membrane, refined edible vegetable oils were on microporous polymeric films polypropylene (PP1E). Various parameters influencing transport, such as pH range in feed solution, initial concentration, acid concentration strip oil viscosities, lifetime, have been studied. maximum flux value ( 1.7 × 10 − 5 mg/cm2/s) was obtained with sunflower oil-supported at 12 solution 0.3 M hydrochloric solution. Under ideal conditions, amount transported within 6 hours. Studies stability morphology revealed that remained constant up about 24 hours then decreased gradually. Morphological studies showed this may be attributed deformation pores shape gradual clogging.
