STUDY OF PB(II) AND FE(III) METAL CATIONS ADSORPTION INTO P-TERTBUTYLCALIX[4]ARENE AS ADSORBENT: KINETIC ADSORPTION

Abstract

This research explain the study about compound of 5,11,17,23-tetra(tButyl)-25,26,27,28-tetrahidroxycalix[4]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.
