Mherie Maika Bondoc, Alver Cheng, Richard.Lumanlan, Rachel Morante, and Anna Maria Parzuelo successfully defended their thesis proposal entitled "Simultaneous Removal of Zinc (II), Manganese (II), and Lead (II) in Water using Coconut Shell Activated Carbon Chitosan γ-Cyclodextrin Composite Beads" last January 21, 2023, in partial fulfillment of their Chemical Engineering Methods of Research.
The rate of heavy metal pollution is rising as industrialization progresses. A few examples of these hazardous metals include zinc (II), manganese (II), and lead (II), all of which have the potential to bioaccumulate and have negative implications on ecosystems and human health. Adsorbents at cheap costs may be found in a wide variety of sources, from mineral compounds to agricultural byproducts. Using inexpensive, naturally occurring materials as adsorbents is indeed economically beneficial and environmentally friendly. However, low-cost materials do not have a particularly high metal uptake capacity. For low-cost materials to perform more effectively, modification is necessary.
Hence, their work aims to study the effect of formulations of Coconut Shell Activated Carbon, Chitosan, and varying γ-Cyclodextrin on the removal of heavy metals (Zinc (II), Manganese (II), and Lead (II)) in water using a Fractional Factorial Design. Adsorption parameters will also be varied such as pH level, initial metal concentration, adsorbent dose, contact time, and agitation speed. Batch experiments will be conducted with varying operational parameters. Adsorption mechanisms will also be analyzed by using adsorption isotherms and kinetic models.
Their research project will be conducted from 2023 to 2024.
