What is it about?
Various contaminants is continuously being released into the environment due to the expensive nature of the existing conventional methods of wastewater treatment. In this work, we prepared two materials from agricultural waste and applied them for the removal of a toxic metal from aqueous media.
Why is it important?
This work is important based on the following:
Perspectives- How have you benefited from the research?
I better understood the behavior of copper in various solution media. The adsorbents surface chemistry and morphology were better understood.
Abstract
Low cost adsorbents prepared from the epicarp of Raphia hookeri fruit were used for the removal of copper (II) ion from aqueous solution. The effects of operational parameters such as pH, concentration and contact time, dosage as well as interference of other ions were studied. Optimum pH for raw and modified biomass were 5.0 and 5.5 with percentage removal of 75.08 % and 95.62 % respectively. Concentration of competing ions greatly reduced Cu2+ removal with both adsorbents while agitation speed had negligible effect on Cu2+ uptake. Adsorbents surfaces were activated as temperature increased thus enhancing adsorbent adsorption capacity at high temperature. Adsorption kinetic data fitted best into the pseudo second order model while the thermodynamics studies confirmed adsorption spontaneity and feasibility. The Freundlich adsorption isotherm best described the adsorption process and the Langmuir maximum monolayer adsorption capacity
for the raw (RHE) and acid treated (ARHE) biomass were 81.97 and 103.09 mg/g respectively. Chemisorption predominate the Cu2+-ARHE system hence desorption efficiency was obtained to be 72.65% with CH3COOH as eluent.

LANDMARK UNIVERSITY CROWNED PRIVATE UNIVERSITY OF THE YEAR VICE CHANCELLOR NAMED VICE CHANCELLOR OF THE YEAR AT THE NIGERIA ACADEMIC EXCELLENCE AWARDS
Landmark University has reaffirmed its position as a leader in Nigeria’s education sector by emerging as the Private University of the Year 2024 – Academic Development at the prestigious Nigeria Academic Excellence Awards (NAEA) on 8th December 2024 red carpet event in Lagos, Nigeria. Adding to this remarkable achievement, the Vice-Chancellor, Professor Kolawole Ajanaku, was honoured as the Vice-Chancellor of the Year 2024 (Academic Development, Private University), underscoring his exemplary leadership in academia.
The NAEA, an annual event, is designed to celebrate and reward exceptional achievements within Nigeria’s education sector. It serves as a platform to recognize individuals and institutions that have demonstrated outstanding academic prowess, innovative leadership, and transformative impact on the nation’s educational landscape.
The organizers highlighted the core objectives of the awards: fostering a culture of continuous improvement, encouraging healthy competition, and elevating education standards across the country. The event showcased the remarkable accomplishments of students, educators, and institutions whose dedication is shaping the future of Nigeria’s education system.
Reflecting on the double recognition, Vice-Chancellor Professor Kolawole Ajanaku expressed his gratitude to the Landmark University proprietor under the Chairmanship of the Chancellor, Dr. David Oyedepo and the Pro-Chancellor, Pst (Mrs) Faith Oyedepo for the platform of Landmark University and their unwavering support. “This recognition is a celebration of our shared commitment to redefining education and creating transformative leaders for global impact,” he remarked. Professor Ajanaku also emphasized that these accolades underscore the university’s relentless pursuit of academic and operational excellence, as well as its focus on innovative practices and impactful research.
Landmark University’s stellar performance on the global and regional stage further cements its reputation for excellence. In the 2024 Times Higher Education (THE) World University Rankings, the institution was ranked 2nd best university in Nigeria, and 3rd in West Africa. Its research efforts earned global recognition when it secured 2nd place in the 2025 THE Interdisciplinary Science Research Rankings. Additionally, Landmark University ranked 1st in Ethical Leadership across Sub-Saharan Africa in the 2024 THE Sub-Saharan Africa University Rankings.
A key driver of Landmark University’s success lies in its alignment with the United Nations Sustainable Development Goals (SDGs). The university’s focus on zero hunger, quality education, and industry innovation earned it a 2nd-place ranking in Nigeria in the Times Higher Education SDG Impact Rankings.
The university’s accomplishments are not limited to rankings; its graduates consistently excel in their professional endeavours. Employers have lauded their resilience, results-driven mindset, and leadership qualities, with many describing them as professionals who combine technical expertise with high standards of professionalism.
Landmark University’s recognition as the Private University of the Year 2024 and Professor Ajanaku’s award as the Vice-Chancellor of the Year 2024 reaffirm the institution’s trailblazing role in higher education. These accolades highlight the university’s transformative vision and enduring commitment to academic excellence, innovation, and leadership development.
To God be all the glory.
