Adsorption and desorption processes of toxic heavy metals, regeneration and reusability of spent adsorbents: Economic and environmental sustainability approach
(Elsevier, 2024-05-19)A growing number of variables, including rising population, water scarcity, growth in the economy, and the existence of harmful heavy metals in the water supply, are contributing to the increased demand for wastewater ... -
Adsorption of phenol and methylene blue contaminants onto high-performance catalytic activated carbon from biomass residues
(Cellpress, 2025-01-15)Organic contaminants from wastewater toxicity to the environment has increased during the last few decades and, therefore, there is an urgent need to decontaminate wastewater prior to disposal. This study aimed to create ... -
Adsorption-capacitive deionization hybrid system with activated carbon of modified potential of zero charge
(Elsevier, 2023-02-15)In this study water solutions are desalinated with carbon electrodes of modified surface charges. The idea is to endow the electrodes with the ability to physically adsorb salt ions without applying potential so as to save ... -
Adsorptive Removal of Heavy Metals from Wastewater Using Low-Cost Adsorbents Derived from Agro-based Materials.
(Springer Nature, 2024-03-29)Recently, anthropogenic activities have evolved into sources of pollution, particularly when it comes to the discharge of harmful heavy metals into the natural environment. As a result, the concentration of diverse heavy ... -
Advances in metal–organic frameworks as adsorbents, photocatalysts and membranes: a new frontier in water purification
(Springer Nature Link, 2024-08-06)Water is an essential and irreplaceable necessity for life on earth, sustaining ecosystems, nourishing agriculture and vital for human survival. However, increasing population and industrialization has exacerbated water ... -
African farmer-led irrigation development: re-framing agricultural policy and investment?
(Taylor & Francis online, 2016-11-09)The past decade has witnessed an intensifying focus on the development of irrigation in sub-Saharan Africa. It follows a 20-year hiatus in the wake of disappointing irrigation performance during the 1970s and 1980s. ... -
Agro-Waste-Derived Hybrid Biochar Exhibits High-Efficiency Removal of Endocrine-Disrupting Compounds
(Springer International Publishing, 2025-04-11)Poor waste management of the products and products used in water sources becomes a problem for living organisms’ health. Using biosorbent from agro-waste materials becomes the solution for waste management and wastewater ... -
