| dc.description | Moringa oleifera has gained significant attention from researchers due to its efficacy as a natural adsorbent for removing pollutants from wastewater. However, this particular M.oleifera is incapable of effectively removing turbidity, total dissolved solids (TDS), total suspended solids (TSS), and electrical conductivity (EC) from wastewater. This necessitates chemical modifications that use concentrated acid and alum, which is not a favourable combination. Thus, this study reported the potential use of combined M.oleifera with activated coconut husk (CH) for water treatment. The effectiveness of using M.oleifera, CH, and a combination of 0.06 g of M.oleifera and 0.02 g of CH to form MOCH 3:1, were evaluated based on turbidity removal at various pH levels (2, 4, 6, 8 and 10) and temperature (25 ℃, 40 ℃, 60 ℃, 80 ℃ and 100 ℃). The TDS, TSS, and EC reduction from synthetic wastewater were also studied using respective coagulants. The surface properties of these materials were examined through the utilization of Fourier Transform Infrared (FTIR) Spectroscopy, Scanning Electron Microscope (SEM), Brunauer-Emmett-Teller-Nitrogen adsorption (BET-N2), and zeta potential. The MOCH 3:1 agreed with the Langmuir, indicating monolayer formation and pseudo-second-order kinetic models, suggesting chemisorption, with R2 value of 0.99. The MOCH 3:1 had a synergistic impact, resulting in the highest removal efficiency of over 90% for turbidity, TDS, TSS, and EC from synthetic wastewater at pH 6 and 25℃. This finding suggests that MOCH 3:1 has superior potential for wastewater contaminant removal than individual coagulants. | |
