Heavy metal contamination in water is a global issue that poses significant health risks, necessitating sustainable, low-cost filtration alternatives. This study investigated the use of nonwoven duck feather fabrics as an alternative waste-filtration medium for the adsorption of lead from synthetic wastewater. An experimental quantitative research design was employed to evaluate the biosorption capacity of nonwoven duck feather fabric (Anas platyrhynchos domestica). Specifically, the nonwoven duck feathers were first pretreated with NaOH to enhance their adsorption capacity. With polypropylene binder fiber, the pretreated duck feathers were bound to 7x7 cm-sized fabrics with varying feather-to-binder ratios (70:30, 75:25, 80:20) using a convection oven. To simulate contaminated wastewater, 10 synthetic wastewater samples were prepared using distilled water and lead nitrate and sealed in plastic containers. Using Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES), the initial lead concentration in the samples was analyzed. After the initial concentration of the samples was measured, the nonwoven duck feather fabrics were placed in plastic containers for 1 hour to adsorb lead from the synthetic wastewater. The samples are then reanalyzed by ICP-OES to quantify the final lead concentrations in the synthetic wastewater. The data is then treated with Kruskal-Wallis to obtain the results. The results showed that nonwoven duck feather fabrics in ratios of 70:30, 75:25, and 80:20 feather-to-binder ratios are capable of adsorbing lead from wastewater. However, there was no significant difference in adsorption capacity or percentage removal among the three ratios.
