“…Among these existing methods adsorption has becoming the most popular and effective technique due to its better performance, availability of various adsorbents, ease of handling, low cost, low sludge generation, short operation time, and no production of secondary compounds which might be toxic (Ramakul et al, 2012). Therefore, much attention has been paid to developing inexpensive sorbents with potential applications in metal removal from aqueous solutions.…”

ABSTRAKLimbah yang mengandung logam berat timbal (Pb) sangat berbahaya bagi lingkungan. Proses pengolahan telah diperkenalkan untuk mengolah limbah, dari proses pengendapan, hingga menggunakan resin penukar ion. Daun ketapang telah di gunakan sebagai media pengolahan air yang digunakan untuk akuarium. Para peneliti telah menunjukkan daun ketapang berpotensi sebagai pengolah air limbah. Penelitian ini bertujuan untuk mengetahui potensi biosorpsi daun ketapang pada limbah yang tercemar logam berbahaya, dengan mempelajari karakteristik biosorpsi, kesetimbangan, kinetika dan termodinamika. Kondisi optimum seperti pH, dosis daun ketapang, waktu kontak dan suhu akan diamati pada penelitian ini. Hasil Penelitian biomassa daun ketapang berpotensi sebagai biosorben, dengan perlakuan asam atau basa daun ketapang ini masih berpotensi sebagai biosorben. Penyerapan sangat dipengaruhi oleh pH, konsentrasi ion Pb, massa adsorben, waktu kontak dan suhu, yang berurutan nilai maksimum nya adalah pH 3, konsentrasi ion Pb 5 mg/L, massa adsorben 0,5 gram, waktu kontak 4 jam, dan suhu 40 ºC. Laju reaksi berjalan pada orde satu dan memenuhi kaidah isotermal Langmuir. Daun ketapang memiliki energi aktivasi yang rendah sehingga cocok untuk dijadikan adsorben alternatif penyerapan logam Pb dari limbah yang mengandung logam Pb.Kata kunci: Adsorpsi, daun ketapang, timbal (Pb) ABSTRACTWaste containing of lead (Pb) is very dangerous for the environment. However, waste treatment process has been introduced to minimize the waste, either by precipitation process or ionic exchange resin. In addition, researchers have shown that ketapang leaves (Terminalia catappa) can be potentially used in waste water treatment. It has been used as water treatment media for fresh water aquarium. Moreover, this research was aimed to find out the potential of ketapang leaves biosorption for waste treatment that has been polluted by heavy metal, such as lead, by investigating the characteristics of biosorption, kinetics and thermodynamics. Maximum conditions of pH, ketapang leaves dose, contact time, and temperature were also investigated in this research. The result showed that biomass of ketapang leaves has potential as biosorbent. Nevertheless, the absorbtion was highly affected by dependent to pH, Pb concentration, adsorbent mass, contact time, and temperature, in which the maximum limits are 3; 5 mg/L; 0.5 gram; 4 hours; 40 ºC; respectively. Reaction rate, moreover, was running
