Parametrical Study for the Effective Removal of Mordant Black 11 from Synthetic Solutions: Moringa oleifera Seeds’ Extracts Versus Alum

Prior studies have examined the ability of Moringa oleifera (MO) seed extract, among other natural coagulants, to remove several types dyes. MO has been proven a high capacity some anionic The aim present study is explore possible use aqueous and saline extracts as biocoagulants for removal Mordant Black (MB11) from solution. Their performances were compared that aluminum sulfate (alum). To do so, various operating parameters investigated such coagulant dose (100–600 mg/L), pH (3–11), initial dye concentration (100–350 sodium chloride (0.2–2 M), sedimentation time (15–90 min). maximum percentages MB11 found be 98.65%, 80.12%, 95.02% alum, extract (MOPW), (MOPS), respectively, at around 6.5 doses 400 mg/L (alum) 500 (MOPW MOPS). coagulation-flocculation mechanism was hypothesized adsorption charge neutralization. two MOPS) showed an interesting versatility towards counter alum which very sensitive this parameter. variations measured three coagulants negligible biocoagulants. Faster recorded when MOPW MOPS used, suggesting existence larger quickly settleable flocs. Considering their coagulative capacity, rapid cost-effective preparation, eco-friendly character, can considered powerful alternatives in remediation wastewaters.
