Separation of Dye from Water Through Supported Liquid Membrane Extraction Process |
| 초록 |
Synthetic dye Rhodamine 6G (R6G) and water separation was investigated using blended organic liquids in a supported liquid membrane (SLM) system. Highest R6G distribution coefficient (KD=18) was obtainedat feed pH=1 using pure octyl alcohol (OcOH). For SLM stability improvement, LM blends were prepared composed of OcOH andpolysiloxane liquid poly (phenyl methyl) siloxane (PPMS). Though permeability decreased at optimal blending condition of 1:1 (w/w), SLM longevity was exhibited in contrast to pure OcOH SLM. Equilibrium experiments revealed Langmuir type of dye adsorption. The dye mass transport behavior was elucidated wherein it showed a decrease in overall coefficient (Ko) at increasing feed concentrations. At varied hydrodynamic conditions, improved Ko values up to Re= 10000 was observed. But beyond this condition, SLM stability is compromised due to shear-induced LM losses.
