Pengaruh Konsentrasi Dan Waktu Aktivasi Spent Bleaching Earth (Sbe) Sebagai A…

ABSTRACT Spent bleaching earth (SBE) is a solid waste produced from the palm oil bleaching industry (CPO). Principally, the SBE can be regenerated and reused as an adsorbent. This research aims to study the effect of variations in HCl concentration and contact time of activation on iodine numbers and surface area of SBE and study the effect of mass variations of Spent Bleaching Earth witho…
