GAMER students John Christopher C. Ebal, Alec Noah R. Marchadesch, Rose Anne G. Oro, Rafaella Marie P. Ortega, and Patrick James B. Polinar bagged the third place in the oral presentation and the people's choice award in the poster presentation for their research entitled "Fenton-like Degradation of Diclofenac in Water using Iron-Impregnated Mussel Shell Biochar (Fe@MSBC)" during the ChE and PetE Plant Design Colloquium, held at Co Po Ty Hall, February 3, 2023.
Emerging pollutants such as diclofenac (DFC) are a cause of concern worldwide due to their persistence in the environment. In particular, pharmaceuticals are very difficult to remove using conventional wastewater treatment methods because of their complex structures. Advanced oxidation processes (AOPs) such as the Fenton and Fenton-like reactions are among the emerging technologies for wastewater treatment due to their capability to completely degrade even recalcitrant pollutants. However, previously-investigated catalysts are expensive. Here, the team reported the viability of using iron-impregnated biochar derived from mussel shells (Fe@MSBC) as a catalyst for DFC degradation in water using sodium percarbonate (SPC) as an oxidant. Fe@MSBC was synthesized by the slow pyrolysis of mussel shells followed by alkali activation, acid neutralization, and iron impregnation.
The ChE and PetE Plant Design and Research Colloquium 2023 is spearheaded by the AdUChESS and AUPESS, the respective student organizations of the chemical engineering and petroleum engineering students at Adamson University. This is the first face-to-face event by the organizations since the pandemic began.
Engr. Erison C. Roque, head of the Chemical Engineering Department, graced the event by highlighting the importance of doing research in the academic life of students.
Engr. Anthony P. Anies and Engr. Jant Erbert S. Garboso, process engineers from JGC, delivered their lecture on plant design during the morning session. In the afternoon, the participating teams delivered their oral presentations. Jesse Louise L. Javier, Karl Steven O. Narte, Mohammad Naif J. Sali, Rolex B. Villaflor, Janine Renz N. Villegas, with their research entitled "Utilization of Conductance Method to Determine Diffusion Coefficients of Butylparaben Triclosan in Water at Infinite Dilution," bested all of the teams. The second place went to Katrin Mae Decembrano, Ma. Anna Carla Hamor, and Denzil Sison for their research on "Removal of Bunker Oil in Contaminated Seawater using Biochar from Chicken Bones via Slow Pyrolysis." The winners received cash prizes and certificates of recognition, and will represent the Chemical Engineering Department in the University-wide Research Colloquium.
