Study of duck feather modification using NaOH to removal iron in acid mine drainage (AMD) has been done. The objective of this study was to determine adsorption capacity. Modification duck feather that 2 g of duck powder was dissolved in 25 mL NaOH with a concentration of 1.00; 1.25; 1.50; 1.75; 2.00; and 2.25 % (v/v), then placed on hotplate stirrer at 50°C and stirred for 24 hours. The results showed that adsorption capacity of Fe by adsorbent of duck feather modification using NaOH optimum at concentration 1.50% and adsorption capacity before & after activation were 36.231 mg/g and 68.493 mg/g and potential to be used as an adsorbent to removal of Fe in acid mine drainage at coal mining.
Key words: adsorption / Fe / duck feathers / NaOH / acid mine drainage
