Optimasi Waktu Kontak Dan Konsentrasi Adsorbat Penjerapan Ion Cr(Vi) Mengguna…

SUMMARY Maredan natural clay is a local potential that has been widely used as an adsorbent material because it has high silica and alumina contents. Maredan natural clay is utilized as an adsorbent material in the adsorption process to adsorb Cr(VI) metal ions. The purpose of this study was to determine the adsorption efficiency, determine the adsorption isotherm and kinetics model as well as…
