Abstract

Calcium oxide decomposed from quail eggshell was used as catalyst for biodiesel synthesis from waste palm oil. Prior to being used, the quail eggshell was decomposed at 600-1100 oC to form calcium oxide and it was characterized by X-Ray measurement, FTIR and SEM spectroscopy to analyze the functional groups and the surface morphology, followed by N2 adsorption desorption methods to determine the surface area. The results of X-Ray analysis powder pattern show that the decomposition of quail eggshell at 900 oC gave calcium oxide that has similar characteristic to the standard CaO from Joint Committee of Powder Diffraction Standard (JCPDS). The FTIR spectrum indicated vibration of calcium oxide from quail eggshell have a similar pattern with the calcium oxide of the standard. The SEM analysis showed that morphology of quail eggshell was changed after decomposition at 900 oC and it have the mesoporous structure.  The biodiesel from waste palm oil was synthesized using CaO catalyst from quail eggshell decomposed at 900 oC. The biodiesel product has density of 0.86 g/cm3, viscosity of 5.50 mm2/s, free fatty acid of 0.56 mg/KOH, and iodine number of 60.49 g I2/100g, respectively. All those biodiesel characteristics meet to the biodiesel standard by the Indonesian National Standard (SNI).

Abstract

Abundant and inexpensive Indonesian natural bentonite was activated by thermal activation at 500 oC for removal of procion red dye as one of the most used synthetic dye in the traditional songket fabric production around Palembang city. Activated bentonite product was characterized by FT-IR, XRD, and thermal analysis. The adsorption process was conducted in batch adsorption system by applying various adsorption parameter condition including, initial pH condition, contact time, and initial dye concentration. The activated bentonite characterization indicates that during the activation process, the structure of the original bentonite was not changed significantly and the result of the thermal analysis revealed that thermal activation at 500 oC was draining the water content without destructing the silica-alumina framework of bentonite. The adsorption kinetics study shows that the procion red adsorption into the activated bentonite follows the pseudo-second order kinetic model. The isotherm adsorption study revealed that procion red adsorption into activated bentonite adapted the Langmuir adsorption isotherm.

Abstract

In this work, two synthetic layered double hydroxides (LDH) consists of Zn2+ as M2+ cation with different M3+ cation, i.e., Al3+ and Cr3+ were used as an adsorbent for Congo Red removal aqueous solution. Both Zn-Al and Zn-Cr LDH were characterized by X-ray diffraction, FT-IR, and BET surface area analyzer. The effect of contact time, initial dye concentration, and temperature were evaluated in a batch technique in order to investigate the characteristic of Congo Red adsorption onto both adsorbents. The experimental data were assessed according to the parameter of adsorption kinetics, isotherm, and thermodynamics. The results of LDH characterization showed that Zn-Al LDH has a higher interlayer distance than Zn-Cr LDH, although Zn-Cr LDH has a higher surface area. The FT-IR analysis indicated the interlayer space of both Zn-Cr and Zn-Al LDH was dominated by CO32- as the interlayer anion species. The adsorption kinetics study of Congo Red on both LDH revealed that the adsorption process followed the pseudo-second-order model. For the adsorption isotherm, the experimental data fit well with the Freundlich model rather than the Langmuir model. The thermodynamic study indicated that the adsorption process that occurred on both adsorbents was spontaneous with exothermic nature.
