A study on water hyacinth Eichhornia crassipes as oil sorbent

Abstract

Abstract:The sorption of diesel, lubricant and castor oils onto different parts (root, stem and leaf) of the dry biomass water hyacinth was studied at the laboratory scale. The parts of the aquapyte water hyacinth (Eichhornia Crassipes) were characterized by physico-chemical methods and the characteristics were used to elucidate the oil sorption process. Hydrophobicity, wettability (capillarity), buoyancy and sorption capacity of oils in the presence/ absence of water were studied to evaluate the suitability of the sorbent for application. In all the three sorbents, the oil sorption capacity increases with the increase of oil film thickness. However of the three parts, the stem has a greater sorption capacity of 9.3, 7.8 and 11.08 g/g for the three oils such as diesel, lubricant and castor oils respectively, even though the root of water hyacinth showed a higher hydrophobicity and surface area. These sorption capacities are comparable with widely used commercial oil sorbent such as nonwoven polypropylene which has a sorption capacity in the range of 10-16 g/g.

Anti-Oxidant Property Of Eichhornia Crassipes In Oil Samples

“…For good performance in protecting engine components against degradation effect by oxidation/corrosion on base oil, the layer has to be closely packed to resist water and oxygen penetration [28]. The actualization of this target comes as a result of strong and dipolar groups and oil dissolve tail known as hydrophobicity tendency with unbranched and long alkyl chain [6] [29].Any material (Eichhornia crassipes) that contain substances of surface-active molecules with high potential in amphiphilic, chitin and chitosan compounds is known as surfactants [30] [31]. With Water hyacinth properties (hydrophobic tail and little hydrophilic tail), contain a unique structure as a surfactant, were the hydrocarbon tail extended into oil phase without losing its properties (insoluble) in water, hence provides good transition between water and oil phase [31].…”

Water hyacinth as a green and sustainable material for carbon aerogel electrodes utilized in membrane capacitive deionization

“…Additionally, water hyacinth contains a wealth of cellulose (25%), hemicellulose (33%), and lignin (10%) in the structural framework, making it a great potential biomass source for various applications. [22,23,[31][32][33][34][35] Specifically, high porosity and water-rich content of WH enable its conversion to porous carbon-based materials. [36][37][38][39] Water hyacinth is becoming a potential resource for the porous material synthesis.…”
