Activated carbon (AC) was modified by the coprecipitation method to induce magnetic properties for the removal of isonicotinic acid (iNA). Magnetization was done by using salts of Fe2+ and Fe3+ as precursors. The induced magnetism in magnetic activated carbon (MAC) was confirmed by Fourier transform infrared and field-emission scanning electron microscopy–electron diffraction spectroscopy analyses. Also, the stability of both AC and MAC was tested by TGA. Batch adsorption experiments were performed using both AC and MAC to see the effects of adsorption time (0–180 min), adsorbent amount (12–40 g/L for AC and 4– 80 g/L for MAC), initial iNA concentration (1.23–6.16 g/L), and temperature (298–333 K) on the removal efficiency. Steady state was reached at 120 min by using both adsorbents. Equilibrium data was best fitted by Langmuir and Temkin isotherms for AC and MAC, respectively. The maximum adsorption capacities were noted to be 0.406 g/g of AC and 0.071 g/g of MAC. Pseudo-second-order model fitted the kinetic data for both adsorbents. The magnetic property in MAC ensured easy separation of adsorbent using magnet after adsorption from the aqueous medium.

“…The broad band between 3000-3700 cm -1 region is attributed to the hydroxyl groups. The peaks at 1094-1571 cm -1 are ascribed to the presence of active carbon [12,14]. Therefore, it can be concluded that Fe 3 O 4 nanoparticles were supported successfully on the palladium-carbon.…”

We reported here the preparation, characterization, and catalytic ability of a Fe 3 O 4 -supported palladiumcarbon (Fe 3 O 4 -Pd-C) as an efficient catalyst in disproportionation of gum rosin. The magnetic nanocatalyst was prepared by a simple method and was characterized by FTIR, XRD, TEM, N 2 adsorption-desorption, VSM, and atomic absorption analysis. The prepared catalyst displayed excellent activity in disproportionation of gum rosin. The magnetic Fe 3 O 4 -Pd-C catalyst was successfully recycled three times with keeping its catalytic performance. The simplicity of the nanocatalyst production method and simple separation and recyclability, on the other hand, make possible the industrial production and application of the catalyst.

“…Kurva histeresis keduanya membentuk urut balik yang simetris ketika dikenai medan serta untuk magnetisasi memerlukan energi yang sangat kecil dengan nilai medan koersivitas Hc yang diperoleh sebesar 59, 37 [1]. Hal ini disebabkan karena karbon yang tidak memiliki sifat magnet atau bersifat diamagnet [41] maka, apabila dikompositkan karbon akan menurunkan sifat kemagnetan nanopartikel Fe3O4 [25,42].…”
