Study on the Adsorption Properties of Novel Calix[6]arene Polymers for Heavy Metal Cations

Abstract

A research has been conducted to investigate the capability of a series of novel calix [6]arenes-based polymers: poly-monoallyloxycalix [6]arene (2a), poly-monoallyloxypenta-estercalix[6]arene (2b) and poly-monoallyloxypentaacidcalix [6] ABSTRAK Telah dilakukan penelitian untuk mengkaji kemampuan adsorpsi senyawa turunan polikaliks[6]arena yaitu polimonoalilkaliks[6]arena (2a), poli-monoalilesterkaliks[6]arena (2b) dan poli-monoalilasamkaliks[6]arena (2c) terhadap kation logam berat seperti Cd(II), Cu(II) dan Cr(III). Adanya gugus aktif hidroksi (-OH) dan struktur senyawa yang menyerupai terowongan sangat memungkinkan pemanfaatan senyawa-senyawa tersebut sebagai adsorben logam berat. Proses adsorpsi dilakukan dengan metode batch pada variasi keasaman (pH), waktu kontak dan konsentrasi awal ion logam. Hasil penelitian menunjukkan bahwa jumlah ion logam teradsorpsi semakin bertambah dengan bertambahnya pH larutan logam. Untuk ketiga polimer, jumlah ion logam Cd(II), Cu(II) dan

Study of Pb(ii) and Fe(iii) Metal Cations Adsorption Into P-Tert-Butylcalix[4]arene as Adsorbent: Kinetic Adsorption.

“…The results of the investigation explained that the value of adsorption capacity was Calix [4]resorcinaren > Chitosan > Calix [4] resorcinarene-chitosan (hybrid) [3]. Prabawati, reported that it can be synthesized compounds of p-t.butyl-37-monoallyloxy-38,39,40,41,42-pentahidroxycalix [6]arene and p-t.butyl-575 37,40-diallyloxy-38,39,41,42-tetrahidroxycalix [6]arene then each of them was treated by polymerization reaction in order so can be obtained poly-monoallyloxycalix [6]arene compound [PMK(6)H]arene and polydiallyloxycalix [6]arene compound [PDK(6)H]arene and was applied to study the adsorption kinetics for Cu(II), Cd(II), and Cr(III) [4,5,6]. Calixarene can form complexes with the type of aromatic compounds in a polar solvent non water.…”

“…Poly-Calix [4]arene-Crown-6 [8,9,10,11], benzyloxycalix [4]arene [12], Calix [4]Resorcine [13,14], calixarene derivative [15], Calix [8] arene Derivative. [16], Bisazocalix [4]arene [17], t-butylcalix [4]arene derivatives [5]. Many attempts have been made to reduce the concentration of heavy metal cations, and guided by a number of facts about the consequences caused by the presence of heavy metal cations, the effort was made to reduce the concentration, especially in the waters.…”

“…

This research explain the study about compound of 5,11,17,26,27,arene (TBCA) that will be used as adsorption material for heavy metal cations. Adsorption using immersion method with variations such as the value of acidity (pH), time of exposure and initial concentration of metal cations have been conducted.

Recent progress to construct calixarene-based polymers using covalent bonds: synthesis and applications

“…It can be assumed that the availability of hydroxyl group (-OH) and channel-like structure of the polymers can be used as adsorbents for heavy metals. 38,39 Zhu et al produced a calixarene-based microcapsule 33 using a non-agitation solution polymerization. This microcapsule showed the remarkable removing ability for metal cations (Scheme 10).…”

Grinding Technique on Synthesis of Calixarene and Its Derivatives

“…Calixarene macrocyclic can be synthesized from aromatic compounds-basic material, both either phenol derivatives and resorcinol. Modifications can be made at the type and number of aromatic units, aldehyde types both aliphatic and aromatic aldehydes [1] or functional group modification with almost unlimited variation [8].…”
