Performance Evaluation of Bulk Liquid Membrane Technique on p-Nitrophenol Removal from Aqueous Solution

Research into the synthesis and use of a novel carrier compound, thiazoethyl methyl eugenoxyacetic acid (TMEAA) for selective transport of Cu(II), Cd(II) and Cr(III) metal ions in the bulk liquid membrane (BLM) technique was conducted. TMEAA was synthesized from eugenol. Eugenol was acidified into eugenoxyacetic acid and subsequently esterified using 4-methyl-5-thiazoethanol. Analysis of the result was performed using GC-MS and FTIR. The TMEAA obtained was liquid, viscous, blackish-brown and fragrant, with a yield of 88%. This compound was soluble in benzene and chloroform but insoluble in methanol. The GC-MS analysis result showed the presence of a single peak, with a retention time of 26.5 min and an area of 100%, while the disappearance of vibration mode at 1727 cm-1 was attributed to acid absorption and the FTIR spectrum indicated that formation of an ester group had occurred. TMEAA was used as a carrier compound in the BLM technique to transport Cu(II), Cd(II) and Cr(III), using chloroform as a solvent. The results showed that TMEAA was more selective for Cu(II) and Cd(II) than Cr(III). Moreover, the research proved that N and S groups of TMEAA were selective for Cu (II) and Cd (II).

ABSTRACT The transport and separation of Cd(II) through bulk liquid membrane technique had been investigated and optimised. Cd(II) was transported through a liquid membrane of chloroform solution containing oxine as mobile carrier and received by EDTA in stripping phase. In compliance with optimum condition, the flux of Cd(II) crossing the membrane was studied, and applied further into a model of the transport system and kinetics mechanism. Concentration of Cd(II) in feed and stripping phases were experimentally determined, and monitored by the atomic absorption spectrophotometer at lmaks 228.8 nm. The model curve of time dependence of Cd(II) reduced concentrations in the feed, membrane and stripping phases show good agreement and characterized as a transport system for Cd(II) interphase involved two consecutive irreversible first order reactions. The rate constant of transport at temperature 28°C are k1 0.0416 minutes-1, k2 0.0354 minutes-1 and activation energy 32.96 kJ mol-1

Study of transport of phenol using the surfactant SDS (Sodium Dodecyl Sulfate), Tween-80 as additive in the source phase and oleic acid, Span-60 additive in the membrane phase with bulk liquid membrane techniques has been performed. Transportation system was in one way using solution of phenol 2.13 x 10 -4 M as the source phase, 30 mL of chloroform as membrane phase, a solution of 12 mL of 0.1 M NaOH as the receiving phase and stirring speed of 340 rpm. The concentration of phenol that transported into receiving phase and remaining in the source is determined by measuring phenol method using 4-aminoantipirin and monitored with a spectrophotometer. The result showed the percentage of transport of phenol into the receiving phase is 93.07% within 120 minutes without any additive surfactant, while for additive oleic acid and Span-60 the percentage of transport phenol is 97.28% and 88.84% within 90 minutes. Phenol transport system analyzed by means of a kinetic model involving consecutive irreversible first order reaction with the constants extraction of phenol from the source to the membrane (k1) of 0.0346 minute-1, 0.0304 min-1, and from the membrane phase into the receiving phase (k2) of 0.0264 min-1, 0.0309 min-1 each for additive oleic acid and Span-60 in the membrane phase. Surfactant SDS and Tween-80 additive in the source phase is not effective to decreased the transport time of the phenol in the phase bulk liquid membrane technique.
