| Abstract | AbstractBatch-mode adsorption study was done for selected heavy metal ions (Pb(II), Co(II), Cu(II), Mn(II), and Zn(II)) using synthetic adsorbent (C-4-methoxyphenylcalix[4]resorcinarene 3) to investigate the effect of different parameters such as contact time and pH. Selectivity of the adsorbent towards a mixture of heavy metals adsorbates was investigated. Results showed optimum agitation time of 30 min at pH 5.6 and initial concentration of 1 ppm for all investigated heavy metals. Different kinetic models of Santosa first-order, Lagergren pseudo-first-order and Ho pseudo-second-order were applied on the adsorption experimental data. Results proved that all adsorption processes were followed and pseudo-second-order kinetic model was adopted. The adsorption capacity of C-4-methoxyphenylcalix[4]resorcinarene towards the selected heavy metal ions was 95.00, 89.76, 89.58, 86.43, and 80.96% for Cu(II), Mn(II), Zn(II), Pb(II), and Co(II), respectively. Selectivity of adsorption was tested on a mixture of Cu(II... |
