Synthesis and application of C-phenylcalix[4]resorcinarene (CPCR) as the Cr(III) and Pb(II) adsorbent has been conducted. CPCR was produced by acid-catalyzed-condensation of resorcinol and benzaldehyde. The characterization of the target compound was performed by IR, 1H-NMR, and LC-MS. The adsorption process using batch system. Most parameters in batch system confirm that CPCR is a good adsorbent for Cr(III) and Pb(II). The Cr(III) uptake was bigger than that of Pb(II), and also Cr(III) adsorption rate was faster than Pb(II). The adsorption kinetic both of Cr(III) and Pb(II) adsorptions in batch followed pseudo 2nd order kinetics model. The results of adsorption equilibrium study showed that in adsorption Cr(III) and Pb(II) onto CPCR, Langmuir isotherm model was more applicable than Freundlich model.
