| Abstract: | The reduce of iron contents in the well water drill and well dig water, using rice husk charcoal as adsorbent with phosphoric acid as activator has been studied. Soaking was 24 hours, at the temperature of 500°C for 4 hours. Iron content determine from sample done before and after adsorbent through by column, stationer phase was activated charcoal and mobile phase was sample. The iron was measure using spectrophotometric, the result of research could be concluded Iron content for well water drill and well dig water before adsorbent trough was 1.2424 mg/L, 1.0905 mg/L and Iron content for well water drill and well dig water after adsorbent trough was 0.3351 mg/L, 0.2479 mg/L. The percentages of reducing from well water drill and well dig water was 72.99 %, 77.24 %. |
| Abstract (other language): | Telah dilakukan penelitian untuk menganalisis kadar besi dari sampel air sumur bor dan air sumur gali, dengan memanfaatkan arang sekam padi sebagai adsorben dan menggunakan asam fosfat sebagai aktivator. Dilakukan perendaman selama 24 jam dan dilanjutkan dengan pengarangan pada suhu 500 °C selama 4 jam. Penentuan kadar besi dari sampel dilakukan sebelum dan setelah dilewatkan adsorben yaitu melalui kolom, dalam hal ini fase diam yaitu arang aktif dari sekam padi dan fase geraknya yaitu sampel. Pengukuran dilakukan secara Spektrofotometri dan diperoleh kadar besi dari air sumur bor dan air sumur gali sebelum dilewatkan adsorben sebesar 1,2424 mg/L, 1,0905 mg/L dan kadar besi dari air sumur bor dan air sumur gali setelah dilewatkan adsorben sebesar 0,3351 mg/L, 0,2479 mg/L. Persen penurunan kadar besi dari air sumur bor dan air sumur gali sebesar 72,99%, 77,24%. |
