Penyisihan Logam Cu2+ Secara Adsorpsi Menggunakan Spent Bleaching Earth (Sbe)…

ABSTRACT Spent Bleaching Earth (SBE) is a solid waste produced from the bleaching industry of palm oil (CPO). In principle, SBE can be regenerated and reused as an adsorbent. This study aims to determine the efficiency and absorption capacity of SBE as an adsorbent in metal Cu2+ adsorption. The adsorption process was carried out by determining the optimum pH from variations 2, 3, 4, 5, 6, …
