“…This means that the Langmuir model can be proper to describe the experimental data. Based on this model, it can be concluded that the active sites on the biosorbents surface were distributed in homogeneous form [19], and monolayer adsorption manner was dominant for sorption [20].…”

“…The unacetylated biosorbent showed higher water uptake at 60 minutes compared to water uptake by the acetylated. The water uptake by the unacetylated leave was 9.15g/g which increases to 21.59g/g (figure 6), stem from 5.06g/g increases to 13.35g/g (figure 7) while root from 6.20g/g increases to 19.30g/g (figure 8) respectively. However, the water uptake for acetylated leave was 5.21g/g which increases to 14.33g/g (figure 6), stem from 2.23g/g increases to 10.35g/g (figure 7) while root from 3.23g/g increases to 16.32g/g (figure 8) respectively.…”

The biosorption of crude-oil spill using acetylated and unacetylated Cissus populnea leave, stem and root biosorbents was investigated in this study. The acetylated and unacetylated biosorbents was characterized by Fourier transform infrared (FTIR) spectroscopy and scanning electron microscopy (SEM). The FTIR spectra confirmed the formation of the acetyl group while SEM morphological analysis of acetylated biosorbent showed rough macrostructure surfaces with large hollows between the strand. The effectiveness of the biosorbents was evaluated based on their ability to remove crude oil from an aqueous solution. The results sho wed that the acetylated biosorbents had higher oil sorption capacities compared to the unacetylated biosorbents. The highest oil sorption capacity was observed for the acetylated stem biosorbent, which had a sorption capacity of 30.09 g/g. The unacetylated leaves biosorbent had the lowest oil sorption capacity, with a sorption capacity of 20.4 g/g. The leaves and roots biosorbents showed intermediate oil sorption capacities. The study also showed that the biosorption capacity of the biosorbents increased with increasing initial oil concentration and contact time, while decreasing with increasing biosorbent particle size. The results suggest that acetylated Cissus populnea biosorbents have potential as an effective and low-cost alternative for the remediation of crude-oil spills.

Disposal of oil‐contaminated wastewater is associated with serious environmental problems since it is drained in seawater or into the ground. These routes of disposal can dangerously affect the lives of both humans and aqua creatures. Therefore, this research study introduces the recovery of petroleum wastewater through the usage of polystyrene‐based adsorbents. High internal phase emulsion polymerization was the used methodology to provide the introduced structures where new approaches have been presented. Unlike the common, the influence of the fabrication parameters of polymeric adsorbents on the oil removal has been investigated. Particularly, different dosing and mixing times were utilized during the preparation stage. Their effect on the polymers surface properties and molecular weights were traced. The obtained adsorbents were subjected to the oil removal stage where optimization of synthesis conditions was taken place. Nearly 92% of the oil content (80 ppm) in the wastewater was removed using the optimized adsorbent. This adsorbent showed surface area of 28.8 m2/g and molecular weight equal 279,970 g/mol. It was acquired by applying 20 min as a dosing time and reaction time of 120 min.

Abstract-Oil spills have tremendous effects on environment, ecology, economy, and the society as a whole. There are several techniques being used for oil spill cleanup i.e in-situ burning of oil, mechanical tools (booms and skimmers), chemical dispersants, steam flushing and also by using natural fibers as sorbents. In this research, oil sorbent material was produced from kenaf (Hibiscus cannabinus L.) fibers. Three sorbent materials were made from of various fiber particle sizes and tested for their oil absorbent properties. The results showed that sorbent produced from a 1.70 cm 2 -sized kenaf fibers achieved the highest absorption value of 8.2327 g/g and saturation value of 0.0385 N/Mins respectively. In this study, the 1.70 cm 2 -sized sorbent also demonstrated the strongest fiber bonding compared to those of 0.04 cm 2 -sized and 0.80 cm 2 -sized sorbents. This was confirmed by microstructure analysis conducted using a Scanning Electron Microscope (SEM). The oil sorbent materials produced in this study were found to have superior absorption value compared to other fiber-based oil sorbents such as Sisal (Agave sisalana), Coir (Cocos nucifera) and loofa sponge (Luffa cylindrica). Index terms-Sorbent materials, kenaf, Hibiscus cannabinus L., oil spill. I. INTRODUCTIONPollution resulting from oil spills poses severe environmental problems around the world. The oil spills pollution not only affects the environment with regard to its hazard but the clean up processes could be costly. In the year 1997, it was estimated that more than USD 136000/tonne spilled were spent for cleaning oil spills in the US alone [1]. The processes involved in cleaning oil spill were normally very complicated and not environmentally friendly [2]. The treatment for oil spills including chemical, mechanical and biological treatments [3]. In mechanical treatment, absorbent of synthetic or natural materials is an effective cost saving option [4].Despite their superior absorption qualities, synthetic materials have low biodegradability. Therefore natural based absorbent material is preferred due to its non toxicity and excellent biodegradability. In recent decades, natural sorbents were produced from natural biomass such as cotton (Gossypium hirsutium), kapok (Ceiba pentandra) [4], Sisal (Agave sisalana), Coir (Cocos nucifera) and loofa sponge (Luffa cylindrica) [5]. This study aims to produce sorbent material from kenaf fiber and to assess its absorption Manuscript received May 6, 2014; revised October 14, 2014 capacity. Kenaf tree (Hibiscus cannabinus L.) is a plant that originated from Africa. The second most important natural fiber after cotton, kenaf is an environmentally friendly plant certified by the Kyoto Protocol for it is obtained from renewable and recyclable source [6]. In Malaysian context, the National Kenaf and Tobacco Board are extensively promoting the application of kenaf as feedstock in manufacturing industries [7].The evaluation of kenaf-based sorbent properties in treating oil spills and waste water treatment are scarc...
