   The removal of Anit-Inflammatory drugs, namely; Acetaminophen (ACTP), from wastewater by bulk liquid membrane (BLM) process using Aliquat 336 (QCl) as a carrier was investigated. The effects of several parameters on the extraction efficiency were studied in this research, such as the initial feed phase concentration (10-50) ppm of ACTP, stripping phase (NaCl) concentration (0.3,0.5,0.7 M), temperature (30-50oC), the volume ratio of feed phase to membrane phase (200-400ml/80ml), agitation speed of the feed phase (75-125 rpm), membrane stirring speed (0, 100, 150 rpm), carrier concentration (1, 5, 9 wt%), the pH of feed (2, 4, 6, 8, 10), and solvent type (CCl4 and n-Heptane). The study shows that high extraction efficiency for ACTP of about 97% was achieved by a bulk liquid membrane at 50 ppm initial concentration of feed; stirring speed of feed phase 130 rpm; stirring speed of membrane phase 100rpm; 0.5 M NaCl concentration; carrier concentration 1wt%; volume ratio of 200ml feed:80ml membrane; feed pH of ACTP is 6,  and 50˚C. The transport kinetics was evaluated using a kinetic model with two consecutive first-order irreversible reactions. The kinetics of (ACTP) transport by bulk liquid membrane was investigated at the best experimental conditions. The activation energy values of the extraction and stripping processes were 1.733 and 1.826 kJ.mol−1. The activation energy confirms that the transport process from solutions is controlled by diffusion.

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).

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.
