“…The thermal degradation of the cellulose of untreated material WH has been recorded in three phases (Figure 8a). The first step associating with volatilization of moisture occurred at the temperature of less than 280 • C. 24 The degradation of cellulosic fibrils was then a second step, especially in terms of 399.87 • C. Evidently, the original material WH existed as a residual solid at 500 • C. 25 Meanwhile, the disintegration of cellulose fibrils of WH-gpoly(LMA) was observed to peak at 325.47 • C (Figure 8b). Significantly, the weight loss process of WH-g-poly(LMA) has so far consisted of a peak at 472.98 • C. The destruction of poly(LMA) side chains is mainly reasonable for an explanation.…”

In this article, a novel oil‐absorbent polymer was synthesized by graft polymerization of lauryl methacrylate (LMA) onto water hyacinth (WH) using 2,2′‐azobisisobutyronitrile (AIBN) as initiator and divinyl benzene (DVB) as a crosslinking agent. The effects of initiator content, LMA content, reaction temperature, reaction time, and crosslinker content on the superabsorbent polymer were investigated. The prepared graft copolymer WH‐g‐LMA was analyzed using FTIR, SEM, XRD, and TGA. In the presence of the better cross‐linker DVB (1.5%) and contact time of about 25 min, the maximal Q (oil sorption capacity) of co‐polymer towards crude and Soybean oils is 23.68 and 25.72 g g−1, respectively. The Q is reduced when sorbent dosage increased, but it increases with increasing the temperature and reaches a maximum of 40 °C. The reusability of co‐polymer is characteristic of 7 sorption/desorption cycles.

This work studies the synthesis, characterization and evaluation of oleophilic gel based on butyl acrylate polymer (BA) to be used in oil spill removing applications. Poly(n-butyl acrylate) was synthesized by solution polymerization and the effect of different factors including polymerization time, initiator concentration, crosslinker concentration, monomer concentration and polymerization temperature on the % yield of butyl acrylate were studied to determine the optimal polymerization conditions. The thermal behavior has been investigated by thermogravimetric analysis (TGA) from 25 to 600°C and differential scanning calorimetry (DSC) from 35 to 400°C. The results showed that the polymer is sufficiently thermally stable to satisfy the demands of oil spill removing applications. The structure of the polymer was confirmed by Fourier Transform Infrared Spectroscopy (FTIR). The morphology of polymer porosity and its ability to absorb oil were observed by scanning electron microscope (SEM). The results showed that butyl acrylate has the ability to absorb oil (gasoline, kerosene, diesel, xylene, and octanol and Mobil oil). Sorption capacity of butyl acrylate polymer at different sorption system (dry system, static system and dynamic system) and the reusability of sorbent several times were studied. In conclusion, we have succeeded in the preparation of oleophilic gel that can be used in oil spill removing applications.

“…Sorbents can be divided into three basic categories: natural inorganic such as clay, sand, sludge, high calcium fly ash, perlite and exfoliated graphite (14)(15)(16)(17). Synthetic organic sorbents are including polypropylene, polyurethane and others (10,(18)(19)(20). In addition, organic natural cellulosic materials sorbents many have been studied include, cotton, bark, milkweed, kapok, rice husk, Wheat straw and bagasse (8)(9)(10)(21)(22)(23)(24).…”

Crude oil spill are a global concern due to the environmental and economic impact as well as harm the beauty of the polluted sites. Date Palm leaves fiber (DPLF) as a natural agricultural fiber, which is environmentally materials, biodegradable, renewable, abundant, and cheap. A hollow cellulosic material like DPLF is a potential sorbent to counter the oil spill pollution. The oil sorption capacity (OSC) of fresh and weathered oils into DPLF as a sorbent was studied. The effects of contact time and temperature on sorption were studied in simulated tap water as well as salty water. The OSC increases with increasing the contact time. The DPLF has given oil sorption capacity of 4.534-7.985 g oil/g sorbent for a contact time of 5-90 min for fresh oil (tap water, at room temperature). This OSC are considered to be good for a sorbent considering it is locally available and not expensive. Fresh oil is having higher OSC at room temperature at all the experimental times (5-120 min). At lower temperature, e.g. 15 °C the adsorption of oil having greater role in increasing OSC, since at low temperature the oil having high viscosity and that will increase the adherence of oil onto the surface of the fibers and within the capillary during drainage. At room temperature and little higher e.g. 25 & 30 °C , the oil will have less viscosity and more diffusion and that will increase the absorption within the internal capillary and lumens of the fibers and that increase the OSC. There is decrease in viscosity at higher temperature e.g. 45 & 60 °C that will increase the diffusion in the oil and increase the segmental mobility of the fibers as well as increasing the penetration of oil into the pores and lumens of the fibers. That will increase the OSC, but much oil will come out during the drainage time (5 min).
