Pengaruh Konsentrasi Dan Ph Terhadap Proses Adsorpsi Komposit Spent Bleaching…

ABSTRACT Many industries produce copper metal waste (Cu) that is classified as heavy metal and toxic. Spent bleaching earth (SBE) and spent mushroom substrate (SMS) can be reactivated to be used as composite adsorbents. This study aims to determine the efficiency and the adsorption capacity of SBE-SMS adsorbent composites against Cu2+ metals with the influence of pH and initial concentrati…
