Evaluation of the performance of calix[8]arene derivatives as liquid phase extraction material for the removal of azo dyes

Novel Water-Soluble Calix[4,6]arene Appended Magnetic Nanoparticles for the Removal of the Carcinogenic Aromatic Amines

“…It is seen from Table 1 that p-C[6]-MN forms a stable complex than p-C[4]-MN with a guest molecule by entrapping it into the cavity. Previously, we have reported (Gungor et al 2008 arene derivatives is smaller and has higher steric hindrance. For this reason, it will be very difficult for azo dye molecules to enter into the cavity of calix[4]arene, resulting in no complex formation.…”

Synthesis and application of calix[4]arene based resin for the removal of azo dyes

“…Immobilization of supramolecule, i.e., cyclodextrin and/or calix[n]arene framework onto a particular resin makes such macrocycle not only selective for the detection due to its chromogenic behavior but also helps in the remediation of industrial organic molecules such as azo dyes [32][33][34][35]. Thus, Amberlite XAD resins have received a considerable attention as basic matrixes for designing new chelating resins [36,37].…”

Extraction of carcinogenic aromatic amines from aqueous solution using calix[n]arene derivatives as carrier

“…It is seen from the Table 1 that p-tert-butylcalix [8]arene carboxylic acid derivative (6) forms a stable complex than p-tert-butylcalix [6]arene carboxylic acid derivative (5) with a guest molecule by entrapping it into the cavity. Previously, we have reported [60] the synthesis and inclusion abilities of calix [4] and calix [8]arene derivatives for selected azo dyes. The results showed that calix [4]arene and its derivatives have no influence on the extraction of azo dyes.…”
