Filtration Test Fe3+ by Duck Feather -Na2S2O5 - High Dencity Polyethylene (HPDE) Composite

Abstract

The problem of disposing of waste into the aquatic environment is heavy metal pollution such as iron (Fe). The manufacture of High Dencity Polyethylene (HDPE) plastic composites with keratin from duck feathers is expected to overcome these problems. This composite was made for duck feathers with 0.325M Na2S2O5 and continued with the percentage between HDPE polyethylene and duck feathers at 30:70. HDPE was dissolved using xylen and benzoyl peroxide and anhydrous maleic acid were added at a temperature of 145oC and duck feathers were added which had been activated with 0.325M Na2S2O5. While stirring until blended, then molded to form pellets while still hot. The continuous filtration test was carried out by placing the composite in a cylindrical tube made of glass with a weight of 4 grams, a flow rate of 200 ml/min. The concentration of iron (Fe) flowed was 100 ppm, and measurements of the water flow were carried out for every 200 ml. The adsorption capacity was calculated using the Thomas Equation. The results showed that the continuous absorption of Fe3+ duck feather composite- Na2S2O5 -HDPE showed that the adsorption capacity was 93.302 mg/g.
