(520d) Philippine Natural Zeolites and Its Potential for Air Quality Management

Air pollution is one of the factors that affect the climate, public and individual health in recent years. One of the most common air pollutants, the tiny particles in the air called particulate matter, contain not only chemical contaminants but also biological pollutants like bacteria and viruses. These can cause respiratory and cardiovascular diseases, reproductive and central nervous system dysfunctions, and cancer. Furthermore, the climate change resulting from the chemical contaminants in the air affects the geographical distribution of infectious diseases. In this global pandemic, air is one of the ways in the transmission of the virus and clean air is imperative to achieving a safe and healthy environment. Adsorption is one of the many processes that can be used to contain these pollutants and reduce their levels to an extent that does not pose environmental concerns. Here, we shall present our work on transforming natural zeolite (Philippine Natural Zeolites) into particles exhibiting sufficient surface area and functionality to reduce pollutant content of ambient air. Furthermore, we shall discuss the properties of these recrystallized and functionalized natural zeolites. Insights on how the transformation of natural zeolites can modulate its properties shall also be present. It is envisioned that this preliminary work can highlight various interventions that enhances the engineering value of natural zeolites for air quality management.
