Catastrophic environmental consequences due to oil spills have been of huge concern over the past couple of decades. Even though numerous oil-absorbing materials have been made to decontaminate waterways, they are limited by the cost of production and scalability of the product. Herein we propose an economical, environmentally benign, and highly sorbent material capable of absorbing several varieties of hydrocarbons, organic solvents and toxic contaminants. The material created was fabricated via sol-gel polymerization of polysaccharides with poly-vinyl alcohol (PVA) via oxidation by metal-nitrate precursors under acidic conditions in aqueous solution, followed by a curing and annealing process under a reducing environment. In this study, we measured the oil adsorption performance of different substituted saccharides within the original synthesis model to determine how pore size and surface area varies depending on different carbon structures. Sugars such as Sucrose, Lactose, Dextrose and others, along with a number of organic acids such as adipic and tartaric acid were used to determine which moieties were responsible for the polymerization process. The materials were compositionally and structurally characterized with SEM and analyzed with BET. Such porous and sorbent material shows promising applicability for environmental remediation.
