Larut resapan adalah cecair yang mengandungi banyak bahan tercemar dan boleh menyebabkan pencemaran jika ia meresap ke dalam persekitaran semula jadi dan aras air bawah tanah. Oleh itu, ia perlu dirawat dengan betul sebelum dilepaskan untuk mengelakkan sebarang kesan buruk. Dalam kajian ini, kaedah penyerapan digunakan untuk merawat larut resapan. Karbon diaktifkan berasaskan daun kelapa sawit dihasilkan dan digunakan sebagai penyerap untuk menjalankan rawatan larut resapan. Kajian ini telah berfokus pada ujian yang dijalankan untuk menghasilkan karbon aktif dari kelapa sawit oleh pengaktifan kimia dengan zink klorida (ZnCl2) dan untuk menentukan keberkesanannya untuk merawat larut resapan. Keputusan ujian makmal terutamanya tertumpu pada penentuan bilangan iodin karbon diaktifkan yang dihasilkan dengan suhu karbonisasi yang berbeza dan nisbah impregnasi zink klorida, analisis mikroskopi elektron (SEM) untuk mengenal pasti struktur mikro karbon yang dihasilkan dan keberkesanan karbon aktif dalam rawatan larut resapan dari segi COD, warna dan besi (Fe) peratusan penyingkiran. Hasil ujian makmal menunjukkan bahawa karbon diaktifkan berasaskan kelapa sawit yang dihasilkan dengan nisbah kelapa sawit ke zink klorida (ZnCl2) iaitu 1: 3 dan suhu karbonisasi adalah 400 ° C telah dikenalpasti sebagai sampel yang mempunyai nombor iodin tertinggi iaitu 516. Bagi rawatan larut resapan, penyingkiran warna maksimum sebanyak 76.03% berlaku apabila dos karbon diaktifkan adalah 1.4g dan masa goncang adalah 40 minit. Penyingkiran COD maksimum sebanyak 76.83% berlaku apabila dos karbon diaktifkan adalah 1.2g dan masa goncang adalah 60 minit. Penyingkiran besi tertinggi (Fe) sebanyak 70.10% berlaku apabila dos karbon diaktifkan adalah 1.2g dan masa goncang adalah 50 minit. Hasil keseluruhannya menunjukkan keberkesanan karbon diaktifkan berasaskan kelapa sawit sebagai penyerap dalam rawatan larut resapan.

Leachate is a liquid that contains a lot of pollutants and can cause contamination if it is infiltrated into the natural environment and groundwater table. Therefore, it should be treated properly before discharged to avoid any adverse effects. In this research, adsorption method was used to treat the leachate. Oil palm frond based activated carbon was produced and used as an adsorbent to carry out the leachate treatment. This research has drawn its focus on the tests conducted to produce an activated carbon from oil palm frond by chemical activation with zinc chloride (ZnCl2) and to determine its effectiveness to treat the leachate. The results of the laboratory test mainly focused on the determination of iodine number of the activated carbon produced with different carbonization temperature and impregnation ratios of zinc chloride, scanning electron microscopy (SEM) analysis to identify the microstructure of the produced activated carbon and the effectiveness of the activated carbon in leachate treatment in terms of COD, colour and iron (Fe) removal percentage. The laboratory test results shown that the oil palm frond based activated carbon that is produced with the ratio of oil palm frond to zinc chloride (ZnCl2) which is 1:3 and the carbonization temperature is 400°C has been identified as the sample that has the highest iodine number which is 516. For the leachate treatment, the maximum colour removal which was 76.03% occurred when the activated carbon dosage was 1.4g and the shaking time was 40 minutes. Meanwhile, maximum COD removal which was about 76.83% occurred when the activated carbon dosage was 1.2g and the shaking time was 60 minutes. Highest iron (Fe) removal which is about 70.10% took place when the activated carbon dosage was 1.2g and the shaking time was 50 minutes. Overall results indicated the effectiveness of oil palm frond based activated carbon as an adsorbent in leachate treatment.
