Leakage, causing a decrease in stripping phase volume. 15 It is usually governed by emulsion rupture and Which are membrane breakage, emulsion swelling, and coalescence. There are three main phenomena that could cause instability of emulsion, Stability remains a great challenge that would hinder its wide applications. Instability to achieve better extraction efficiency. Studies have been conducted to minimize the occurrence of emulsion Presence of two thermodynamically unstable interfaces. 13 According to Kumar et al., 14 instability of emulsion occurred consequently due to the Which diminishes some of the solute separations that have been achieved. Thus, an unstable liquid membrane tends to be ruptured or broken apart, Membrane resistance toward high shear stress during solute extraction. The stability of an emulsion is defined as liquid This phenomenon has impeded the widespread applications of ELM onĪ larger scale. Despite the promisingįeatures of ELM, the major drawback of ELM is its instability, and Method to apply to remove acetaminophen in water. This process, which is consideredĪs economical due to its low energy consumption and solvent quantity,Įnables us to simultaneously extract and strip. Ratio for mass transfer, so the system is capable of recovery of soluteĮven at low concentration selectively. Transformation products) are above their detection limits.Įmulsion liquid membrane (ELM) has a high interfacial area-to-volume In the environment, and it was reported that 631 (of which 127 are 11 According to Lyons, 12 global surveysįound 713 pharmaceuticals (of which 142 are transformation products) 10 For example, several types of pharmaceuticalĬECs such as acetaminophen, atenolol, furosemide, and metformin haveīeen detected in Langat River, Malaysia. Penetrate municipal sewage and sewage treatment plants. 9 Therefore, a mixture of pharmaceuticals and their metabolites Metabolized or remain intact before being excreted. Of medical substances are managed orally, while some drugs are either 5− 8 Nearly 3000 various substancesĪre used as pharmaceuticals ingredients, which include molecules withĭifferent physicochemical and biological properties. Is pharmaceutical contaminants, which have been widely publicized One of the most studied groups of emerging contaminants Improper disposal of worn containers and pristine medicine, and treatment Livestock treatments, manufacturing process, aquaculture treatments, Wastes are discharged to the environment by multiple paths such as 3 According to Alistair, 4 pharmaceutical The improper treatment of these chemicals. The more substantial environmental crisis can be caused by It is essential to extract acetaminophen from biological production The increasing demand for acetaminophen (ACTP) in many applications, Species of pharmaceutical contaminants mixed together. Regarding the potential “cocktail” effects of different To make matter worse, there is some concern 1 Chemical compounds such as acetaminophen (ACTP),Ĭarbamazepine, diclofenac, ibuprofen, and salicylic acid can be easilyĬomponents exist in small concentrations, they still lead to chronic Other than human consumption, veterinary usageĪlso contributes to the release of CEC into the environment. Recently, there has been a growing realization of pharmaceuticalĬontaminants of emerging concern (CEC) in the aquatic environmentĪt concentrations that are adequate for causing catastrophic effects
