Topic: Waste Management And Environmental Pollution Treatment

Description: Introduction: The indiscriminate disposal of carbide ash waste by automobile industries have created serious problem to the environment because it affects man and the ecology of their vicinity. Aim: is to investigate the quantity, quality and application of calcium carbide and its waste ash generated by the automobile industries.Methodology: the raw and carbide ash samples were characterized using analytical technical such as X-ray diffraction XRD , X-ray fluorescence XRF , scanning electron microscope SEM and Fourier transform infrared FTIR spectroscopy. The results of the X-ray diffraction XRD identified Portlandite, Litharge and Hematite mineral phases in raw Carbide while Portlandite and Calcite mineral phases for both carbide ash waste 1 CAW1 and carbide ash waste 2 CAW2 . Expected Results: the XRD will help to identify the mineral phases present in both materials, XRF elemental analysis will reveal the chemical compositions of raw carbide A and carbide ash B , the IR spectrum in all the samples indicative of the functional groups present in each sample. The SEM will reveal the morphology or shapes of the raw carbide and carbide ash generated from the automobile industry. Contribution to knowledge/society: This research will help to determine the chemical composition of the samples and application in the making of cement and plaster of Paris, and how it can be used to treat textile dye effluent.

Application of Prepared Cocoa Pod Husk Activated Carbon for the Removal of Emerging Contaminants from Pharmaceutical Wastewater

The increasing discharge of pharmaceutical wastewater containing emerging contaminants such as antibiotics, non-steroidal anti-inflammatory drugs, and preservatives poses significant risks to aquatic ecosystems and human health due to their persistence and limited removal by conventional treatment processes. The aim of this study is to develop and evaluate prepared cocoa pod husk activated carbon (CPHAC) as a low-cost, sustainable adsorbent derived from agricultural waste for the remediation of micropollutants. Cocoa pod husk activated carbon was carbonized and chemically activated with ZnCl₂. Sample was characterized using XRD, SEM, TEM, FTIR, XRF, BET, and TGA to determine quality of the sample. Batch adsorption experiments was conducted on real pharmaceutical wastewater and optimize with key parameters such as adsorbent dosage and contact time to remove methyl paraben, ethyl paraben, tetracycline, and ciprofloxacin. The removal efficiencies increased with dosage and contact time to achieve 88 – 99 % for parabens and ciprofloxacin, and 62–74 % for tetracycline under optimized conditions. This findings demonstrate that CPAC is an effective, eco-friendly, and economically viable alternative adsorbent for the treatment of pharmaceutical wastewater by promoting circular economy principles by valorizing cocoa pod waste abundant in Nigeria.
