Studi Isoterm Adsorpsi Logam Cu2+ Menggunakan Limbah Spent Bleaching Earth (SBE) Sebagai Adsorben

Abstract

Pollution caused by Cu2+ metal has a very negative impact on living things. An effort that can be done to reduce the metal content of Cu2+ is the adsorption process. Utilization of Spent Bleaching Earth (sbe) can be used as an adsorbent to reduce the metal content of Cu2+ in the process. SBE is a porous material in the category of bentonite clay with high adsorption ability. The purpose of this study was to test the equilibrium model of adsorption isotherm on Cu2+ metal with SBE as an adsorbent in the Langmuir and Freundlich model equations.
