Activated Carbon and Coconut Husk as Oil Spill Adsorbent
CABLAO, Carmela Beatrice9A
Background of the Study
The US Department of Energy has stated that 4.9 Million liters of fossil fuel are being poured out into bodies of water each year. A big spill might easily double that amount.
The long-term damage to various species and their habitat and nesting or breeding grounds is one of the most far-reaching environmental effects caused by oil spills. Even many species that spend most of their lives in the sea–such as different species of sea turtles–are mostly nestling ashore. Sea turtles can be harmed by oil they meet while going to the shore.
Surface area and pore size utilization of the created activated carbon as oil – spill adsorbent were decided by the implementation of Brunauer, Emmett and Teller (BET) strategy in a computerized AUTOSORB-IC analyzer system that uses AS 1-win software. Samples were out gassed before the 77.4 K physical adsorption utilizing nitrogen. The dubinin-radushkevich structure decided microspore volumes. Evident and strong adsorbent intakes were calculated using processes mentioned in Ahmedna et al (1997). Adsorbent permeability was responsible for the following interactions (Akinyemi and Taiwo, 2004).
Carbon – based absorbents were considered the greatest contenders for huge surface area, low density, outstanding mechanical properties, fine chemical security, ecological friendliness and high pore quantity.
Coconut coir is indeed a farming waste from fibrous coconut crust (Cocos nucifera L.) fruit. The use of coconut coir is examined to evaluate its efficiency as potential future replacements for inorganic adsorbents in oil contamination decontamination surges.
Statement of the Problem
1. How much coconut husk and activated carbon is needed to make the product
2. What are the elements of the coconut husk and activated carbon that makes
an effective oil adsorbent?
3. How effective are the coconut husk and activated carbon in terms of:
a) Volume of oil adsorb
b) Time to adsorb oil
c) Adsorb oil from different H 2 O samples
To test the efficiency of the product in terms of:
Its ability to hold oil for a certain amount of time
Its ability to collect all oil surrounding it
Its ability to adapt to different H2O samples
1. Different amounts of coconut husk and activated carbon will make the
2. a. Properties and elements of coconut husk will make the adsorbent
b. Properties and elements of activated carbon will make the adsorbent
3. Coconut husk and activated carbon are effective in terms of:
a. Resisting water and adsorbing oil
b. Time – efficient adsorbing of oil
c. Overall adsorbency
Significance of the Study
1. The farmers will profit by selling their left over coconut husks
2. The Department of Environment and Natural Resources (DENR) will have
A better process to reduce the oil spill in the environment.
3. The environment:
a. The oil spill will be reduced.
b. The garbage will be reduced because of the usage of coconut husk
and activated carbon in this research.
4. The harm of the inhaled chemicals from the oil spill will be reduced. This
will help the people living near the bodies of water affected.
Definition of Terms
Oil: General word for a multitude of chemicals whose primary mutual properties are viscosity at average temperatures, density far less than water, inflammability, water insolubility and viscosity in ethyl and alcohol.
Oil spills are an unintentional leak of petroleum into a body of water, after ships, offshore drilling tankers or deep sea pipelines often display a danger to aquatic life and the natural world.
Coconut husk appears to consist of sclerenchyma tissue. Sclerenchyma tissue operates to render the plant tough and stiff. This tissue is visible in stems, vascular piles, leave veins and tough cover of crops and nuts.
Carbon is a consistent, non metallic chemical component happening in pure translucent state as diamond and as graphite, and in the joint shape and form as a colleague of all organic material including fossil fuels and natural gas, and of inorganic substances such as limestone and bicarbonate of soda represents only 0.19 percentage point earth’s crust.
Hydrophobic actually means “water fear.” Hydrophobic surfaces and particles repel water. Water – repellent fluids such as oil are segregated from water. Hydrophobic particles are usually nonpolar, which means that atoms responsible for making the molecule do not create a static electric field. These polar opposite regions of electricity entice water molecules in polar molecules. Without an electrical current against particles, water could not create hydrogen bonds with molecules. The water particles then establish more hydrogen bonds together with the non-polar molecules.
The hydrophobic effect is triggered by the accumulation of non-polar molecules. Large macromolecules could have water – repellent segments that fold the molecule so they can be near together, away from the water. Many amino enzymes in proteins are hydrophobic, which enables the proteins to retain their complex forms. The hydrophobic effect applies to organisms because many water – repellent particles on the rim of an organism aid them to control the amount of water and nutrients in their structures.
Oleophilic components are compounds which have a kinship for oil absorption. The oleophilic components industry is a relatively recent technology and its use in oleophilic grabbers and market crashes is expected to rise gradually. The sector grew by 6.4 percent in 2015, primarily given the increasing use of oleophilic products in customer industries such as manufacturing, food service and hydro power. Technological advancements in the oleophilic components economy have propelled to a growing stimulation of carbon based sponges such as carbon nanotubes, nanowire PVC membranes and laser – induced porous polymer sponges. Oleophilic material is popularly used in application manufacturing industries such as oil and petroleum, production assembly, hydropower plants and environmental services.
