Abstract
Zeta potential of calixarenes has been reported for the first time. The water-soluble calixarenes
has been used as dispersion media in solid/liquid interface. p-sulfonato-calix[4]arene (PSC4) and
p-sulfonato-calix[8]arene (PSC8) were synthesized and characterized by FTIR, NMR, mass
spectrometry, and HPLC techniques. It was proved that the zeta potential is a fast and simple measurement to know the adsorption behavior of sufonato calixarnes on calcite. The chemisorption of p-sulfonato-calix[n]arene was confirmed by shift in iso electric point, adsorption studies and FTIR. The calculated free energy of adsorption value and its sign suggests the chemical interaction between the calcite surface and p-sulfonato calix[4]and[8]arene.
