Research ArticleOpen accessIn the abstractAssessing Soil Fertility Status of Rehabilitated Degraded Tropical RainforestAiza Shaliha Jamaluddin, Arifin Abdu, Hazandy Abdul-Hamid et al.An assessment of forest rehabilitation program in relation to soil fertility status by using soil indices could provide fundamental information on soil suitability for species preferences and improve the effective technique for future rehabilitation program in tropical rainforests. This study was conducted in order to characterize the soil properties and identifying the soil fertility status of rehabilitated and secondary forests. … …American Journal of Environmental Sciences, Vol. 9, Issue 3 · 19 Jul 2013 · 8,457 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparing the Fertility of Soils under Khaya ivorensis Plantation and Regenerated Degraded Secondary ForestsYetti Heryati, Arifin Abdu, Mohd Noor Mahat et al.Problem statement: It is widely accepted that conversion of natural forest to other land use types leads to deterioration of soil fertility and increased soil compaction which consequently become degraded secondary forests. Degraded secondary forest or forestland is indicated by low in soil fertility and organic matter due to imbalance input and output from original vegetation. Forest plantation through planting … …American Journal of Applied Sciences, Vol. 8, Issue 5 · 17 May 2011 · 8,509 accessesView PDFCite
Research ArticleOpen accessIn the abstractPlastic Membrane Electrodes of Coated Wire Type for Micro Determination of Quininium Cation in Pharmaceutical TabletsLaila Abdullah Al Shatti, Hayat Mohammed Marafie, Adel Fahmi ShoukryProblem statement: Silver and copper all-solid state wire sensor electrodes of quininium cation with different ion exchangers have been prepared and used in pharmaceutical analysis. A comparative study with a reference method is applied in order to investigate the validity of the proposed method for potentiometric analysis of pharmaceutical compounds containing quinine. Approach: A Nernstian equation was proved for all … …American Journal of Applied Sciences, Vol. 8, Issue 2 · 28 Feb 2011 · 7,690 accessesView PDFCite
Research ArticleOpen accessIn the abstractChemical Characteristics of Compost and Humic Acid from Sago Waste (Metroxylon sagu)Auldry Chaddy Petrus, Osumanu Haruna Ahmed, Ab Majid Nik Muhamad et al.Problem statement: Agriculture waste such as Sago Waste (SW) has a potential to cause pollution either on land or in water. In order to reduce this problem, a study was conducted to investigate the effect of three different treatments on the chemical characteristics of compost and humic acid from SW. Approach: The study had three treatments which were: T1: SW … …American Journal of Applied Sciences, Vol. 6, Issue 11 · 30 Nov 2009 · 8,088 accessesView PDFCite
Research ArticleOpen accessIn the abstractProduction 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 PDFCite
Research ArticleOpen accessIn the abstractArsenic Adsorption on Bauxite Mineral Using Batch Equilibrium TestFares Yahay Alshaebi, Wan Zuhairi Wan Yaacob, Abdul Rahim Samsudin, Esmail AlsabahiProblem statement: Study suggested a solution to remove arsenic contamination from contaminated water. Approach: Bauxite, which is a mineral, was proposed as natural remediation material used in this study. Bauxite was collected from Johor mining company in Teluk Ramunia, Johor Bharu, Malaysia. Batch equilibrium test was performed in accordance to different initial concentrations, shaking time and different initial pH values. … …American Journal of Applied Sciences, Vol. 6, Issue 10 · 31 Oct 2009 · 6,836 accessesView PDFCite
Research ArticleOpen accessIn the abstractSorption of Phenols: Influence of Groundwater pH and of Soil Organic Carbon ContentSilvia Fiore, Maria Chiara ZanettiProblem statement: Physical and chemical properties of soil, groundwater and pollutants deeply influenced the type and the strength of sorption phenomena involving hydrophobic organic contaminants: Soil fraction of organic carbon (foc) and cation exchange capacity, groundwater pH and pollutants hydrophobicity were with undoubtedly the predominant issues. Approach: In this study an experimental study of the sorption of phenol and 2-nitrophenol … …American Journal of Environmental Sciences, Vol. 5, Issue 4 · 31 Aug 2009 · 7,007 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesalination of Saline Sludges Using Ion-Exchange Column with ZeoliteA.E. Ghaly, M. VermaA flushing process followed by a zeolite based ion-exchange process were developed for the treatment of saline sludges from oil and gas exploration sites. The particle size distribution of sludge sample indicated the presence of very fine sand and clay. The electrical conductivity of the sludge was 42.2 dS m-1 indicating very saline sludge and the Cation Exchange Capacity (CEC) … …American Journal of Environmental Sciences, Vol. 4, Issue 4 · 31 Aug 2008 · 7,062 accessesView PDFCite
