“…There was also a mild C=O vibration detected in the 1750-1780 cm −1 region, unlike the sharp vibration for biodiesel around a similar position as well as a C-O ester diagnostic bond at 1246 cm −1 . In contrast, other studies showed no peak in the 1750-1780 cm −1 region for diesel [5,32]. Other peaks for regular diesel are presented in Table 4.…”

The study characterized heterogeneous biocatalyst synthesized from sucrose, saw dust, and chicken egg shells using Fourier Transform Infrared (FTIR) spectroscopy coupled with Attenuated Total Reflectance (ATR) technique. Acidic sulphonate (–SO3H) groups were more visible in the spectrum generated for carbonized and sulphonated sucrose than in carbonized and sulphonated saw dust. This was highlighted further by the significantly higher conversion percentage achieved for sulphonated sucrose (62.5%) than sulphonated saw dust (46.6%) during esterification of expired sunflower oil (p=0.05). The spectra for calcinated egg shells also showed that the most active form of calcium oxide was produced at calcination temperature of 1000°C. This was confirmed in the single-step transesterification reaction in which calcium oxide generated at 1000°C yielded the highest biodiesel (87.8%) from expired sunflower oil. The study further demonstrated the versatility of the FTIR technique in qualitative analysis of biodiesel and regular diesel by confirming the presence of specific characteristic peaks of diagnostic importance. These findings therefore highlight the potential of FTIR-ATR as an inexpensive, fast, and accurate diagnostic means for easy identification and characterization of different materials and products.

“…Palm oil of FTIR spectrum had aliphatic hydrocarbon bonds such as -CH 3 at the area of 2951 cm -1 and 1376 cm -1 then -CH 2 at the area of 2852 cm -1 and 1476 cm -1 . There also were occurred aliphatic ester bonds such as -C=O in the area of 1743 cm -1 and -C-O in the area of 1150 cm -1 that corresponded as the literature [24,25].…”

FABRICATION AND CHARACTERIZATION OF STARCH BASED BIOPLASTICS WITH PALM OIL ADDITION. In this work, starch-based bioplastics in advancing its properties were positively arranged with the addition of palm oil. Starch-based bioplastics were produced by dry blending method and compression technique with mixing starch and glycerol (3:1, w/w) then adding palm oil at various concentration (0%, 2.5%, 5% and 7.5% w/w). Morphology of bioplastics presented that palm oil wrapped bioplastics granules which influenced hydrophobicity properties of bioplastics compared by increasing contact angle of bioplastics from 45.95 o (0% of palm oil) to 61.98 o (5% of palm oil). This result indicated that the addition of palm oil could develop the properties of bioplastics to hold absorbing water molecules. Moreover, the melting point of bioplastics also affected shifting temperature from 115 o C to be 100 o C that could save the energy needed during heating process. FTIR analysis showed that C=O group at wavenumber 1747 cm -1 was dependable the interaction between starch-glycerol and palm oil. Furthermore, the addition of palm oil would accelerate the biodegradation process. Although the mechanical properties of bioplastics have not increased, the addition of palm oil on bioplastics fabrication is an alternative to improve the characteristic of bioplastics, especially physical, thermal, hydrophobicity and biodegradation properties.

“…e weaker peak at 1100-1000 cm −1 on modified sago hampas after adsorption of oil is probably because the interaction between the cellulose backbone (C-O) with palm oil at optimum condition. e extra peak between 1800 cm −1 and 1700 cm −1 on modified sago hampas after adsorption shows the present of C�O which was contributed by ester from palm oil [26]. e effect of sorption time, adsorbent dosage, and pH were carried out.…”

Adsorption based on natural fibre seems to widely used for oily wastewater recovery due to its low cost, simplicity, feasibility, easy handling, and effectiveness. However, oil sorbent based on natural fibre without modification has low adsorption capacity and selectivity. Thus, this paper proposes chemical modification of sago hampas to improve its adsorbent efficiency for the removal of palm-based cooking oil. The chemical modification was performed using a cationic surfactant, cetyltrimethylammonium bromide (CTAB). The chemical and surface properties of both unmodified and modified sago hampas were characterized by Fourier-Transform Infrared (FTIR) and Scanning Electron Microscopy (SEM). Parameters studied for the removal of cooking oil using modified sago hampas were sorption time, adsorbent dosage, and initial pH. The removal capacity was also compared using unmodified sago hampas. The results showed that additional functional groups were introduced on the surface of modified sago hampas. Modified sago hampas also showed a greater porosity than unmodified sago hampas. These properties enhanced the adsorption of palm-based cooking oil onto the surface of modified sago hampas. Modified sago hampas shows better removal of palm-based cooking oil than unmodified sago hampas, where 84.82% and 68.08% removal were achieved by modified and unmodified sago hampas, respectively. The optimum adsorption of palm-based cooking oil was identified at 45 min sorption time, pH 2, and 0.2 g adsorbent dosage.
