MPW sludge and MPWT sludge were incorpotared as inorganic adsorbents in batch reactors containing aqueous Cr(VI) solutions varying between 1 and 25 mg/L. MPWT sludge was obtained with alum coagulant. A dry particulate (powder) form of sludge samples were used at a 5 g/100 mL dosage. Isotherm studies indicated that Cr(VI) adsorption by these andesite- oriented adsorbents may be characterized using a Freundlich model for MPW sludge and a Langmuir model for MPWT sludge.eninfo:eu-repo/semantics/closedAccessArticle114137141N/AWOS:000344912500005Q4
