Separation of Cu²⁺, Cd²⁺and Cr³⁺in a Mixture Solution Using a Novel Carrier Poly(Methyl Thiazoleethyl Eugenoxy Acetate) with BLM (Bulk Liquid Membrane)

Abstract

Abstract. The separation process using a novel carrier polyeugenol has active groups N and S has been done with the technique BLM. Polyeugenol has groups active N and S was synthesized from eugenol which is then polymerized into polyeugenol. This polymeric compounds was then acidified become acidic poly (eugenoksi acetate). After the acid formed , then the synthesis was continued by add 4-methyl-5-tiazoleetanol to form esters poly (methyl thiazole eugenoxy ethyl acetate) (PMTEEA). IntroductionDue to the discharge of large amounts of metal-contaminated wastewater, industries bearing heavy metals, such as Cd, Cr, Cu, Ni, As, Pb, and Zn, are the most hazardous among the chemical-intensive industries. Because of their high solubility in the aquatic environments, heavy metals can be absorbed by living organisms. Once they enter the food chain, large concentrations of heavy metals may accumulate in the human body. If the metals are ingested beyond the permitted concentration, they can cause serious health disorders [1].One method for separating metal ions are liquid separation membrane [2]. In the liquid membrane technique, carrier compounds play an important function. Compounds carrier as a facilitator is determinant in the separation performance from the feed phase. A carrier compounds should has high ability to extraction via stable complex formation within the membrane, having high selective separation towards certain species, has good solubility as well as diffusion coefficient in the suitable organic solvent (membrane) and can be used in relatively a small amounts [3]. Besides that, a selectivity compounds carrier towards certain metal ions determined by the active groups on the carrier compound.Carrier compounds will form complexes with metal ions through chemical bonds between the active group with a metal ion, this establishment is based on the theory HSAB (Hard and Soft Acids Bases), this theory states that in general the metal acid hard ions (such as alkali, alkali earth, and Cr 3+ )

In-Situ Ionic Imprinted Membrane (IIM) Synthesis Based on Acetic Polyeugenoxy Acetyl Tiophen Methanolate for Gold(III) Metal Ion Transports

“…The ester derivative of the eugenol compound has been proven to be used as a liquid membrane carrier with selectivity, which can be adjusted depending on the functional group included [9]. In previous studies, esters of sulfur (E) functional group eugenol, namely thiophene-2-methyl-2-eugenoxy acetate as carrier compounds in liquid membranes for the recovery of soft metal Ag + (silver ions) [10].…”

The Influence of type of Functional Groups on the Adsorption Selectivity of Ionic Imprinted Polymer (Iip) Fe

“…5 5 g polyeugenol (0,03 mol) was added into the boiling flask with the size 100 mL, after that, it was added 33% NaOH solution (0,825mol) as much as 17,5 mL. Then, the mixture was stirred for about 30 min.…”

Separation of Chrom (Vi) From Electroplating Waste Using Polymer Inclusion Membrane (Pim) Method

“…Jenis membran difusi ini disebut Polymer Inclusion Membrane (PIM). PIM menunjukkan kelebihan dari membran cair lainnya khususnya SLM diantaranya adalah kestabilan yang sangat tinggi, carrier yang hilang selama proses dapat diabaikan, carrier yang digunakan lebih hemat, fluks yang dihasilkan lebih tinggi dan lebih serbaguna (Kusumocahyo et al, 2006) serta keselektivan carrier (Djunaidi et al, 2017).…”
