DETERMINATION OF REMOVAL EFFICIENCY OF METHYLENE BLUE FROM AQUEOUS SOLUTION USING CHEMICALLY ACTIVATED CARBON PRODUCED FROM MANGO SHELL

ABSTRACTThe presence of methylene blue (MB) in wastewater is a major concern in the environment due to its low biodegrability and harmful effect on man. The treatment of effluent containing such dye is important where adsorption on activated carbon (AC) produced from agricultural waste is of great choice. Optimization of the removal efficiency of MB from aqueous solution onto AC prepared from mango shell was investigated. The AC was prepared from mango shell, activated with BaCl2 at I.R (0.03...

OPTIMIZATION OF CONDITIONS FOR THE PRODUCTION OF ACTIVATED CARBON FROM MANGO KERNEL SHELL USING BARIUM CHLORIDE AS THE ACTIVATING AGENT

ABSTRACTThis study was conducted to remove mango shell waste which is one of the seasonal environmental nuisance items and recycle it as a precursor for the production of activated carbon. Discarded mango shells were sourced from local vicinity, and they were washed thoroughly to remove dirt, sundried and reduced to smaller sizes. Two-Level Factorial Design under Factorial Methodology of Design Expect (10.0.1) software was employed to optimize interaction of impregnation ratio (0.033 - 0.167 ...

INVESTIGATION INTO THE EFFECTS OF TEMPERATURE ON ITAKPE IRON CONCENTRATE MAGNETO VISCOUS FLUIDS

ABSTRACTThis research work show cases the potentials of Itakpe Iron concentrate for Magneto-rhelogical abilities. The concentrate was first ball milled to size reduce it then subjected to low magnetic strength from magnetic bits in-situ the magnetic fluid.It was determined that temperature affected the fluid inversely, as temperature increased at the shear rates from the viscometer and Newtonian viscosity calculated reduced, giving a negative relationship between temperature and Newtonian vis...

Extraction and Phytochemical Analysis of Oil from Neem and Morning Oleifera Seeds and Leaves

ABSTRACTPhytochemicals are chemical compounds produced by plants, generally to help them thrive or thwart competitors, predators, or pathogens. These chemicals are produced by plants through primary or secondary metabolism (Breslin A,2017) . These work was done to determining the presence of phytochemicals such as Tannins, Saponin, Alkaloids, Anthraquinone, Phlobatannins, Flavonoids and  Cardiac Glycosides (e.g Steroidal Ring or Terpenoids and cardenolide) from oil extracted from mo...

Effect of Surface Area on the Extraction of Silica from Rice Husk and Wheat Husk

Silicon dioxide , also known as silica (from the latin silex), is an oxide of silicon with the chemical formula SiO2, most commonly found in nature as quartz and invarious   living   organisms.   In   many   parts   of   the   world,   silica   is   the   major constituent of sand. Silica is one of the most complex and most abundant families of materials existing as a compou...

COMPARATIVE STUDY OF THE DIFFERENT METHODS USED IN RE-REFINING USED LUBRICATING OIL

Engine oils are made from crude oil and its derivatives by mixing of certain other chemicals (additives) for improving their certain properties. Lubricating oil is used to lubricate moving parts of engine, reducing friction, protecting against wear, removing contaminants from the engine, act as a cleaning agent, and act as an anti corrosion and cooling agent.Accordingly, this research effort focuses on comparative study of re-refined engine oils by acid treatment, acid/clay treatment, so...

Research Paper on Hand Sanitizer

AbstractThe 15th of October has been decreed a day to focus on germs specifically. It’s the germs on our hand that are in the firing line .The world health organization estimates that 3.5 million children die from diarrhea and lower respiratory tract infections each year. That’s why global hand washing day was decreed. Sanitation of hand has a great effect on the wellbeing of life in general. By maintaining ones sanitation different kind of diseases which are caused by contact can ...

Conversion of Waste Plastics to Fuel Oil

AbstractWaste plastic disposal and excessive use of fossil fuels have caused environmentconcerns in the world. Both plastics and petroleum derived fuels are hydrocarbons thatcontain the elements of carbon and hydrogen. The difference between them is that plasticmolecules have longer carbon chains than those in LPG, petrol, and diesel fuels. Therefore, itis possible to convert waste plastic into fuels.The main objectives of this study were to understand and optimize the processes of plasticpyr...

A Comprehensive Research on Preparation and Characterization of Corn Curbs Adsorbent

In preparation and characterization of adsorbent obtained from corn curbs, potassium hydroxide was used as an activating agent at ratio of 1:1, 7:8 and 3:4 with the corn curbs and their pH values were found to be 8.5, 8.03 and 8.0 respectively, ash content were found to be 41.56, 46.78 and 48.31wt%. The BET surface area values were 17.762461, 25.455146 and 201.54631m2/g respectively and the best activated carbon formulation arrived was 3:4 AC.INTRODUCTION  An  adsorbent  is  a  porous ...

Corrosion Studies of Mild Steel in Biodiesel Obtained from Ghee Butter (Mann Shanu)

It is of no doubt that one day, fossil fuels, which the whole world highly depends on, will come to a halt in a few decades to come. To this reason, researches have been geared towards alternative sources of energy: biodiesel, a form of renewable energy (energy that can be regenerated once used up), is one that has been made known and being tested in some parts of the world. Due to the fact that biodiesel is hygroscopic (absorbs water readily from the atmosphere), as well as other fact...

CHARACTERIZATION OF NON-EDIBLE OIL FROM WASTE PLANT MATERIALS FOR BIOIDIESEL PRODUCTION

Oil obtained from orange peels and velvet tamarind nut by solvent extraction (n-hexane and acetone) using the soxhlet extractor were investigated as feedstock’s to determine some of the suitable parameters such as iodine value, saponification value, specific gravity, density, acid value and free fatty acid value, and their percentage yield that are suitable for biodiesel production. The density of orange and tamarind oil were found to be 0.9326g/cm3 and 0.8541g/cm3 respectively, their...
