<![CDATA[Andisol, karbon aktif, dan zeolit memiliki luas permukaan, porositas, dan kapasitas tukar ion yang efektif dalam menyerap kontaminan air. Penelitian ini bertujuan untuk mempelajari pembuatan adsorben berbasis andisol/zeolite/active carbon dilanjutkan dan kinerja adsorpsi serta parameter kinetika adsorpsinya untuk penjernihan air gambut. Tanah andisol dan zeolit diaktivasi dengan larutan NaOH 3 M dan komposisi tanah andisol, zeolit, dan karbon aktif divariasikan dengan perbandingan berat 100:0:0; 0:100:0; 0:0:100; 50:25:25; 25:50:25; dan 25:25:50 (b/b). Data menunjukkan kapasitas adsorpsi terbesar dihasilkan oleh komposisi tanah andisol:zeolit:karbon aktif pada komposisi 25:50:25 yaitu 39,67 mg/g dengan persentase penghilangan sebesar 81,72%. Isoterm adsorpsi mengikuti isoterm Redlich-Peterson. Analisis kinetika menunjukkan bahwa adsorpsi mengikuti model kinetika pseudo orde dua dengan konstanta laju adsorpsi sebesar 0,32 g∙mg-1min-1 dan qe sebesar 5,38 mg/g. Berdasarkan hasil tersebut campuran tanah andisol/zeolite/karbon aktif berpotensi digunakan sebagai absorben dalam penjernihan air gambut.Andisol/Zeolite/Active Carbon-based Adsorbent for Peat Water Treatment. Andisol, Activated Carbon, and Zeolite have a high specific surface area, porosity, and ion exchange capacity, effectively absorbing water impurities. This study aims to study the andisol/zeolite/active carbon-based adsorbent preparation and its adsorption capacity for peat water treatment. Andisol soil and zeolite were activated with NaOH 3 M solution and the composition of Andisol Soil/Zeolite/Activated Carbon were varied of 100:0:0; 0:100:0; 0:0:100; 50:25:25; 25:50:25; and 25:25:50 (wt%). Data shows that the largest adsorption capacity obtained for Andisol/Zeolite/Activated Carbon composition of 25:50:25 (wt%) of 39.67 mg/g and 81.72% for removal percentage. The isotherm adsorption followed Redlich-Peterson isotherm. The kinetics analysis showed that the adsorption followed the pseudo-second-order kinetics model with an adsorption rate constant of 0.32 g∙mg-1min-1 and qe of 5.38 mg/g. Based on these results, the mixture of andisol soil/zeolite/activated carbon has the potential to be used as an absorbent in peat water purification.]]>
