dc.description.abstract | Limbah kulit nangka mengandung selulosa yang dapat dimanfaatkan sebagai adsorben suatu senyawa penyebab pencemaran lingkungan. Porositas adsorben kulit nangka ditingkatkan melalui aktivasi menggunakan H3PO4. Adsorben yang dicirikan menggunakan spektroskopi inframerah transformasi Fourier menunjukkan puncak serapan khas untuk selulosa. Analisis morfologi menggunakan scanning electron microscope memperlihatkan bahwa karbon kulit nangka teraktivasi memiliki porositas yang lebih besar daripada tanpa aktivasi. Karbon aktif dengan konsentrasi H3PO4 2 M memberikan efisiensi adsorpsi optimum sebesar 51% dan waktu kontak adsorpsi optimum pada menit ke-30. Proses adsorpsi karbamazepina menggunakan karbon aktif kulit nangka mengikuti model kinetika orde dua semu dengan persamaan isoterm Freundlich. Studi termodinamika adsorpsi mengindikasikan bahwa proses adsorpsi terjadi secara eksoterm. | id |
dc.description.abstract | Jackfruit peel waste contains cellulose that can be utilized as an adsorbent to adsorb environmental pollutants. The porosity of the jackfruit peel adsorbent was increased through an activation process using H3PO4. Fourier transform infrared spectroscopy characterized the resulting adsorbent, which shows characteristic cellulose absorption peaks. Morphological analysis using scanning electron microscopy reveals that activated jackfruit peel carbon has larger porosity than the unactivated ones. Through an H3PO4 concentration of 2 M, the activated carbon exhibits an optimum adsorption efficiency of 51% and an optimum adsorption contact time achieved at 30 minutes. The adsorption process of carbamazepine using the activated carbon follows a pseudo-second-order kinetic model with the Freundlich isoterm equation. Thermodynamic studies of the adsorption process indicate that the adsorption process is exothermic. | id |
