Polymer inclusion membranes based on CTA/PBAT blend containing Aliquat 336 as extractant for removal of Cr(VI): Efficiency, stability and selectivity

Abstract: Cellulose triacetate (CTA) and poly(butylene adipate-co-terephthalate) (PBAT)-based polymer inclusion membranes (PIMs) containing ionic liquid (tricaprylmethylammonium chloride (Aliquat 336)) as the carrier extractant were obtained for the facilitated and selective transport of Cr(VI) ions. The composition of PIMs was optimized in terms of the CTA/PBAT ratio. The obtained membranes were investigated using different techniques in order to show the influence of the membrane composition and the ionic liquid prese… Show more

“…Although the special properties obtained by surface modification, the most used and reported adsorbents present high cost, low selectivity to specific chemical species, and complicated procedure for modification. Over the past years, studies on new materials that present higher potential and efficiency to adsorb heavy metals have increased significantly 24,29 …”

“…Moreover, it is considered more efficient than other techniques, as it can reduce the concentrations of metals to below 100 ppm and produce less waste 20–22 . In the adsorption process, several materials have been extensively used to remove heavy metals, and they include zeolite, kaolinitic, mineral silicates, sawdust, biomass, lignin, chitosan, and other natural polymers 23–25 …”

“…Removal and extraction of dissolved heavy metal ions from aqueous media are generally accomplished by several methods including chemical precipitation, ion exchange, adsorption [3][4][5][6], membrane filtration [7], coagulation, flocculation, flotation, and electrochemical methods [8][9][10]. Among all these methods, adsorption is considered as the effective technique for the removal of heavy metals from aqueous solution because of advantages like the low cost, availability, profitability, ease of operation and efficiency [11,12].…”

“…Membrane contactors are widely used for separating and recovering pollutant species, especially in trace amounts [1][2][3]. In recent years, polymer inclusion membranes (PIMs) have attracted a lot of interest in a wide range of separation process, and they have grown in popularity, especially for small organic compounds [4] and metal ion separation from aqueous solutions [5,6], such as chromium [7], aluminum [8], Au(III) [9], copper (II) [10], zinc [11], cadmium [12], cobalt [13], and lead [14]. Moreover, PIMs have reached the agricultural sector for the extraction of pesticides that, due to their toxicity, pose a great risk to human health [15].…”
