Adsorpsi Ion Logam Nikel(II) oleh Kitosan Termodifikasi Tripolifosfat

Abstract

A r t i c l e I n f o A b s t r a c tKeywords: chitosantripolyphosphate, adsorbent, adsorption capacityResearch on adsorption of nickel(II) metal ions by thermodynamic chitosan tripolyphosphates has been conducted. The purpose of this study was to make chitosantripolyphosphate to be used as an adsorbent of Ni(II) metal ions at pH conditions and optimum contact time. The method used to make chitosan-tripolyphosphate was the ionic gelation method. The resulting adsorbents were then characterized using Fourier Transform Infra Red (FTIR) spectroscopy. The results showed that the optimum condition of chitosan-tripolyphosphate to Ni(II) metal ion adsorption was at five hours contact time and pH of 5. Maximum adsorption capacity value was 3.3 mg/g using Langmuir isotherm model. A b s t r a kKata Kunci: kitosantripolifosfat, adsorben, kapasitas adsorpsi Penelitian tentang adsorpsi ion logam nikel (II) oleh kitosan termodifiksai tripolifosfat telah dilakukan. Tujuan dari penelitian ini adalah membuat kitosan-tripolifosfat untuk digunakan sebagai adsorben ion logam Ni(II) pada kondisi pH dan waktu kontak optimum. Metode yang digunakan untuk membuat kitosan-tripolifosfat adalah metode gelasi ionik. Adsorben yang dihasilkan selanjutnya dikarakterisasi menggunakan spektroskopi Fourier Transform Infra Red (FTIR). Hasil penelitian menunjukkan bahwa keadaan optimum adsorpsi kitosan-tripolifosfat terhadap ion logam Ni(II) adalah pada waktu kontak lima jam dan pH=5. Nilai kapasitas adsorpsi maksimum yang terhitung adalah sebesar 3,3 mg/g dengan menggunakan model isotherm Langmuir.

Modifikasi Membran Kitosan Tertaut Silang Tripolifosfat Untuk Deteksi Ion Cu(II)

“…Presentase unsur O (oksigen) juga mengalami kenaikan karena adanya penambahan tripolifosfat (TPP) yang strukturnya banyak mengandung unsur P dan O. (Rahayu and Khabibi, 2016). Pengaruh konsentrasi ion Cu(II) terhadap perubahan warna membran digunakan untuk mengetahui daerah kerja…”

Study of Equilibrium and Kinetics of Pb(II) in Solution Using Persimmon Tannin Gel as an Adsorbent

“…The filtrate was further separated by filtering using Whatman filter paper and then analyzed by atomic absorption spectrophotometer to determine the concentration of Pb(II) metal ions which were adsorbed using equation (2).…”

“…Lead metal is widely used in the battery, cable, and paint industry (as a coloring agent), electroplating pesticides, and it is widely used as an antipyretic agent in gasoline. Lead is also used as a pipe joint formulation, which results in household water have a high possibility of containment from lead itself [2]. The process of removing heavy metals from liquid waste has been done in several ways, such as chemical precipitation [ 3 ], extraction using certain solvents, ion exchange, reverse osmosis [ 4 ], and adsorption [ 5 ].…”

Effect of Electrolyte Composition on Nickel Removal Process from Artificial Electroplating Wastewater Using Two-Room Electrodeposition Cells

“…Salah satunya adalah penyakit kanker pada paru-paru dan rongga hidung manusia jika terkena kontak langsung. Di perairan, logam nikel (Ni) mempunyai baku mutu yang diijinkan sebesar 1,0 mg/L sehingga pengolahan air limbah yang mengandung Nikel harus dilakukan untuk meminimalis konsentrasi Ni yang masuk ke perairan [2].…”
