Abstract

Particulate matters (PMs) refer to tiny solid or liquid particles suspended in the air and can have a significant impact on human health, contributing to climate change and other environmental hazards. To mitigate the hazards associated with PMs, various techniques are employed for its removal from the air. This necessitates research on improving the efficiency of air purification filters and reducing harmful emissions into the air. This study focused on preparing reduced graphene oxide (r-GO) to modify filters used in air particle monitoring devices. The goal was to investigate how r-GO affects PM adsorption efficiency. Various spectroscopic techniques, including energy-dispersive X-ray spectroscopy (EDX), inductively coupled plasma (ICP), and laser-induced breakdown spectroscopy (LIBS), were used to assess the modified filters’ adsorption efficiency quantitatively and qualitatively towards PMs. The results showed that r-GO-modified filters revealed higher PM adsorption efficiency than control filters. The r-GO's exceptionally large specific surface area and pore volume account for its remarkable performance. This novel approach is expected to gain significant attention and contribute to the development of improved air purification technologies.
