Abstract

Tujuan pada penelitian ini adalah melihat kemampuan bentonit yang sudah diaktivasi menyerap nitrogen yang berasal dari air limbah pabrik kelapa sawit. Sampling bentonit di peroleh dari daerah Sungai rengas Provinsi Jambi. Bentonit dihaluskan dan diaktivasi menggunakan larutan HCl 1,6 M. Pengukuran kandungan nitrogen menggunakan instrumet UVvis. Hasil penelitian menunjukkan bahwa bentonit sudah diaktivasi mempunyai kemampuan yang relatif sama kemampuannya dalam menyerap unsur nitrogen, dengan massa 1 gram dan waktu kontak 90 menit daya setrap bentonit terhadap unsur nitrogen yang berasl dari air limbah The aim of this research was to evaluate the profile of activated bentonite to adsorb the nitrogen that presence in the palm oil industry wastewater. Bentonite was collected from River Rengas, Jambi Province. Bentonite was milled and activated using 1.6 M solution of HCl. The nitrogen content was measured using UV-Vis. The result showed that during the 90 minutes of contact time, 1.0 gram of the activated bentonite was able to adsorb nitrogen from palm oil industry wastewaterup to 81.50%.

利用苯酚被激活为油棕厂废水的氮吸收剂

本研究的目的是了解活性膨润土从棕榈油厂废水中吸收氮的能力。膨润土样本取自占碑省 Sungai Rengas 地区。膨润土经粉碎后使用 1.6 M HCl 溶液进行活化。使用 UVvis 仪器测量氮含量。结果表明，经过活化的膨润土对氮元素的吸附能力比较接近，质量为 1 克、接触时间为 90 分钟的膨润土对废水中的氮元素有较强的吸附能力。这项研究的目的是评估活化膨润土吸附棕榈油工业废水中氮元素的能力。膨润土取自占碑省的伦加斯河。膨润土经研磨后使用 1.6 M 的盐酸溶液进行活化。使用紫外可见光测量氮含量。结果表明，在 90 分钟的接触时间内，1.0 克活化膨润土对棕榈油工业废水中氮的吸附率高达 81.50%。
