Pengaruh Massa Dan Waktu Kontak Terhadap Proses Adsorpsi Komposit Spent Bleac…

ABSTRACT Heavy metal pollution is found a lot in the environment, One of the alternative to reducing heavy metals from industrial waste by using adsorbent composite made from Spent Bleaching Earth (SBE) and Spent Mushroom Substrate (SMS). This study aims to determine surface area of the adsorbent, determine efficiency and adsorption capacity, determine mass optimal, contact time optimal an…
