Polypropylene/lignin blend monoliths used as sorbent in oil spill cleanup

Abstract

With increasing industrial development, frequent oil spillages in water; therefore, it is imperative and challenging to develop absorbents materials that are eco-efficiency, cost-effective, and pollution prevention. In this study, sorbents obtained from Lignin incorporated with Polypropylene in different levels loading 0, 10, 20 % wt using thermally induced phase separation Technique (TIPS). The Polypropylene/Lignin blend monoliths were fabricated and compared in terms of morphological, thermal, and wetting characterizations. The successfully blending of different lignin concentrations with preserved the chemical structure of the polymer was confirmed by FTIR analysis. Thermogravimetric tests displayed that the existence of Lignin has changed the onset temperature (Tonset) of the blending sorbents, decreasing as the loading of Lignin is increased. The contact angle measurement showed a decrease in the hydrophobicity of sorbents with increasing lignin loading, Polypropylene/Lignin blend monoliths showed better absorption toward oils (soybean – engine) as compared to Polypropylene itself. PP10L showed an improvement in the oil sorption capacity around 2 times compared to the Polypropylene. These excellent features make Polypropylene/Lignin blend monoliths more competitive promising candidates than commercial absorbent.

Polypropylene/Lignin/POSS Nanocomposites: Thermal and Wettability Properties, Application in Water Remediation

“…Polypropylene showed peaks at 2949, 2916, 2866, 2837, and 1375 cm −1 that were attributed to the C–H stretching. The peaks at 1375, 1358 and 1330 cm −1 represent the syringyl group, the –CH 3 bonding, and the C–O stretch, respectively [ 18 ]. The spectra of all the blends had these peaks, as can be seen in Figure 4 a.…”

“…The half-filling angle was taken as 45°, the contact radius was considered as equal to the particle radius (maximum value), the contact angles for glycerol, oil, PEG, and deionized water were taken as 92°, 67°, 48°, and 101°, respectively. [25][26][27] Of course, these values could be taken differently owing to the dynamic character of the particle collision process, but this would not change the overall conclusion drawn on the effects of liquid properties on the bounce of particles. The trends of the viscous dissipating force and the capillary force against different particle sizes for the four different liquids taken in this work are displayed in Figure 6.…”
