Recent oil tanker accidents in the sea are very serious, not only since they pollute the environment but also because they release heavy oil. The preparation of activated carbon from agricultural waste increases economic return and reduces pollution. On carbonized fibers, sorption capacity for different kind of oils was determined. Fibers extracted from bagasse and carbonized at 300◦C for 2 hr were found to have a high performance for sorption, recovery and recycling of heavy oils, even the viscous ones. Sorption capacity showed strong dependence on the weight of sorbent and oil film thickness. Their recycling performance was excellent as they can be used for six cycles until they reach 50% of the sorption capacity of the 1st cycle. Comparison between the prepared carbonized fiber and a commercial sorbent has been done and showed that the prepared sorbent could be used as sufficient sorbent more than the commercial sorbent used.

Over the past years and present, the expanding number of oil spills occurrences has gotten an overwhelming chemical test to the marine or oceanic environment, and the environmental issues around the globe are becoming more problematic and more acute, be it oil spills or effluents caused by oil and gas or petrochemical industries. The main point of this current investigation is the synthesis of activated carbon (AC) from various agricultural waste materials, bamboo, and banana fibers, as one of the most promising methodologies or applications in treating oil spills constitutes high sorption capacity. The physicochemical feature of the synthesized AC samples was analyzed by FTIR spectra and N2 physisorption. More specifically, the AC samples derived from bamboo (BAMB-AC) at activation temperature 550 ℃ indicate the highest specific surface area (2,760.47 m2/g), and sorption capacity at 3.3678 g/g with the total pore volume, mesopore volume, external surface area being 3.364 cm3/g, 1.811 cm3/g, and 1,601.634 m2/g, respectively, and maximum oil sorption capacity at 4.418 g/g for BANA-AC with activation ratio 7:1 (H3PO4), and surface area at 2,172.234 m2/g.

Abstract Bamboo trees are one of the fastest growing trees in tropical rainforests around the world, they have various uses ranging from construction to fly ash generation used in oil and gas cementing, to development of activated carbon which is one of the latest uses of bamboo trees. This paper focuses on development of activated carbon from bamboo trees for carbon capture and sequestration. The need for improved air quality becomes imperative as the SDG Goal 12 and SDG Goal13 implies. One of the major greenhouse gases is CO2 which accounts for over 80% of greenhouse gases in the environment. Eliminating the greenhouse gases without adding another pollutant to the environment is highly sought after in the 21st century. Bamboo trees are mostly seen as agricultural waste with the advent of scaffolding and other support systems being in the construction industry. Instead of burning bamboo trees or using them for cooking in the local communities which in turn generates CO2 and fly ash, an alternative was considered in this research work, which is the usage of bamboo trees to generate activated, moderately porous and high surface area carbon for extracting CO2 from various CO2 discharge sources atmosphere and for water purification. This paper focuses on the quality testing of activated carbon that can effectively absorb CO2. The porosity, pore volume, bulk volume, and BET surface area were measured. The porosity of the activated carbon is 27%, BET surface area as 1260m²/g. Fixed carbon was 11.7%, Volatility 73%, ash content 1.7%.

Activated carbon prepared from grapefruit peel, an agricultural solid waste by-product, has been used for the adsorption of Cr(VI) from aqueous solution. The effects of adsorbent dosage, pH and temperature on adsorption of Cr(VI) were investigated. The maximum adsorption yield was obtained at the initial pH of 3. The dynamical data fit very well with the pseudo-second-order kinetic model and the calculated adsorption capacities (23.98, 24.33 and 24.81 mg/g) were in good agreement with experiment results at 20°C, 30°C and 40 °C for the 100 mg/L Cr(VI) solution. The Freundlich model (R2 values were 0.9198-0.9871) fitted adsorption data better than the Langmuir model. The calculated parameters confirmed the favorable adsorption of Cr(VI) on the activated carbon prepared from grapefruit peel.

The Impact

We herein report an experimental study to explore the effects of impact inertia, film thickness and viscosity on the dynamics of shape deformation of a drop impacting a liquid film. We have identified that the spreading dynamics shows a weak dependence on impact inertia, but strongly depends on the film thickness. For a thick film, the liquid surface deforms and absorbs part of the impact energy, and hence inhibits spreading of the drop. For a thin film, the drop motion is restricted by the bottom solid substrate, promoting spreading. The periodicity of the capillary controlled shape oscillation, on the other hand, is found to be independent of impact inertia and film thickness. The damping of the shape oscillation shows strong dependence on the film thickness, in that the oscillation decays faster for smaller film thicknesses, due to the enhanced viscous loss.
