Research ArticleOpen accessEvery word in the titleProduction of Potassium and Calcium Hydroxide, Compost and Humic Acid from Sago (Metroxylon sagu) WasteC. P. Auldry, O. H. Ahmed, A.M. Nik Muhamad et al.Problem statement: Agriculture waste such as Sago Waste (SW) has a potential to cause pollution when the waste is discarded into rivers. In order to add value to SW, a study was conducted to produce potassium and calcium hydroxide, compost and Humic Acid (HA) from SW. Approach: The SW was air-dried and some grinded. The grinded SW was incinerated at … …American Journal of Environmental Sciences, Vol. 5, Issue 5 · 31 Oct 2009 · 7,583 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titlePreparation and Characterization of Hybrid Organic-Inorganic Composite Material: Polymerization of m-Aminobenzoic Acid-Intercalated Into Zn/Al-Layered Double HydroxidesRasheed M.A.Q. JamhourLayered double hydroxides of aluminum and zinc (Zn/Al-LDH’s) were synthesized directly by hydrolysis at room temperature as reported elsewhere. After characterization, the material was reacted with m-aminobenzoat anion (m-NH2C6H4COO-) which undergoes polymerization in the interlayer space; resulting in the formation of a matrix with polymeric organic macromolecule. The resulting material along with the host LDH’s compound of Zn/Al-Cl was characterized … …American Journal of Applied Sciences, Vol. 2, Issue 6 · 30 Jun 2005 · 6,586 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleMethanol-Based Transesterification Optimization of Waste Used Cooking Oil over Potassium Hydroxide CatalystCholada Komintarachat, Sathaporn ChuepengProblem statement: Waste used Cooking Oil (WCO) harmfully affected to environment and human’s health can be a feedstock for producing biodiesel. Approach: The conversion of Fatty Acid and Free Fatty Acid (FFA) of WCO with 15.0% w/w FFA content to biodiesel was studied through transesterification reactions. This work investigated the effects of alcohol and catalyst quantity, reaction time and temperature … …American Journal of Applied Sciences, Vol. 7, Issue 8 · 31 Aug 2010 · 9,739 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsEquilibrium Kinetics and Isotherm Studies of Cu (II) Adsorption from Waste Water onto Alkali Activated Oil Palm AshZaira Zaman Chowdhury, Sharifuddin Mohd. Zain, Rashid Atta Khan, Abdulbari Abdulrahman AhmedProblem statement: Heavy metal accumulation in waste water could affect aquatic life, human health and overall ecosystem adversely. Therefore, in recent years much emphasis has been given for the use of industrial waste material as low cost adsorbents for removal of metallic contaminants from waste water. Approach: Present study deals with the adsorption equilibrium and kinetics of Cu (II) cation … …American Journal of Applied Sciences, Vol. 8, Issue 3 · 25 Mar 2011 · 7,933 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsThe Biodiesel Production from Roast Thai Sausage Oil by Transesterification ReactionWasan Theansuwan, Kitrichai TriratanasirichaiProblem statement: This research is to study the feasibility of biodiesel production from roast Thai sausage oil by transesterification process. Approach: The objective of this study was to investigate the effects of potassium Hydroxide (K2OH3) as heterogeneous catalyst (3-9% (wt) of the feedstock) and methanol-oil molar ratio (3:1-12:1) on the yield and properties (flash point and fire point) of the … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 1 · 12 Mar 2011 · 8,157 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsControlling the Morphology of Nano-Hybrid MaterialsAbdullah I. Al JaafariProblem statement: It is known that layer double hydroxide is one of the nano ordered layered compounds and possesses plate-like morphology if carefully crystallized. Approach: In this study, Co-Sn LDH consisting of divalent and tetravalent cations was prepared with new morphology. XRD patterns of the prepared Co-Sn LDH showed that the interlayer spacing of the LDH was 0.78 nm and … …American Journal of Applied Sciences, Vol. 7, Issue 2 · 28 Feb 2010 · 7,886 accessesView PDF Cite
