    Abstract: It is generally believed that electroosmosis is comprehensively described by the corresponding Helmholtz-Smoluchowski equation. Consequently, this belief has contributed to the fact that electroosmosis is still viewed as occurring in a time-invariant aqueous medium characterized by constant viscosity and dielectric permeability. Considering the ine... Show More

    Abstract: The present study aims to valorize the hulls of Lophira lanceolata, an agricultural by-product in Benin. This natural resource, which is abundant in tropical countries, including Benin, has so far been considered as a biodegradable waste and treated as such. However, it has adsorption properties that can be exploited by transforming it into activat... Show More

    DOI: 10.11648/j.ajpc.20221104.13
    Abstract: In pineapple industries and processing units, peelings constitute waste piled up in landfills and therefore cause real problems for environment. The present study aims to develop this available and neglected bioresource, through the study of the kinetics of its conversion into bioethanol by fermentation with a view to its use as a biofuel. To do th... Show More

    Abstract: Synthesis of iron oxide nanoparticles by green approach is extremely promising because of its non-toxicity and environmentally friendly behavior. However, few studies have been done on the synthesis of iron oxide nanoparticles using grapefruit peel extract. The aim of the present study was to remove indigo carmine dye from industrial effluent using... Show More

    Abstract: Water is an essential resource for maintaining aquatic life and the quality of aquatic products. However, sediments are the most important place of accumulation of metal residues and their remobilization in the food chain. The objective of this work is to study the water physicochemical quality and the mercury contamination levels of the sediments ... Show More
