Research ArticleOpen accessIn the abstractElectroanalytical Determination of Doripenem using a Screen-Printed ElectrodeNora H. Al-ShaalanProblem statement: The performance characteristics of Sensitive Screen-Printed (SPE) and Carbon Paste (CPE) electrodes were investigated for the Determination of Doripenem (DP) in pure, pharmaceutical preparations and biological fluids. Approach: The proposed electrodes is characterized in terms of plasticizer type, response time, pH and temperature. Results: The two electrodes showed nearly Nernstian behaviours over the concentration range of 2×10−4-5×10−2 mol/l … …American Journal of Pharmacology and Toxicology, Vol. 7, Issue 1 · 21 Feb 2012 · 7,664 accessesView PDFCite
Research ArticleOpen accessIn the abstractSuitability of Using Phragmites australis and Tamarix aphylla as Vegetation Filters in Industrial AreasWafa’a A. Al-TaisanProblem Statement: Many soils of different areas of the world are subjected to heavy metal pollution due to human activities especially the industry. These metals are hazardous to human health and could affect ecosystems. Toxic metal pollution in water and soil is a major environmental problem and most conventional remediation approaches do not provide acceptable solution, hence the studies of … …American Journal of Environmental Sciences, Vol. 5, Issue 6 · 31 Dec 2009 · 8,450 accessesView PDFCite
Research ArticleOpen accessIn the abstractGeochemical Distribution of Trace Metals and Assessment of Anthropogenic Pollution in Sediments of Old Nakagawa River, Tokyo, JapanH.M. Zakir, Naotatsu Shikazono, Kazuo OtomoThe geochemical distributions of cadmium (Cd), copper (Cu), chromium (Cr), lead (Pb) and zinc (Zn) were examined in sediments collected from Old Nakagawa River (NR), Tokyo, Japan. A widely used 5-step sequential extraction procedure was employed for the fractionation of the metals and the concentrations were measured in the liquid extracts by inductively coupled plasma mass spectrometry (ICP-MS). The association … …American Journal of Environmental Sciences, Vol. 4, Issue 6 · 31 Dec 2008 · 7,455 accessesView PDFCite
Research ArticleOpen accessIn the abstractCharacterization of Maturity Level in Laying Hen Manure by Chemical and Thermogravimetric AnalysisAlice Dall’Ara, Francesco Antolini, Laura Billi et al.This study aims at investigating maturity levels in manure from laying hens in order to encourage its agronomic re-utilization. In fact the use of unstable/insufficiently mature manure could potentially damage both soils and crops. Effective, easy to reproduce methods are needed in order to assess bio-stabilisation and maturity levels, particularly for biomass that has not undergone conventional composting. This study … …American Journal of Environmental Sciences, Vol. 4, Issue 4 · 31 Aug 2008 · 6,542 accessesView PDFCite
Research ArticleOpen accessIn the abstractAbolishing Toxicity of Copper by Some Environmental Factors Using Green Alga Chlorella vulgarisAdel A. Fathi, Mohamed M. Azooz, Mohamed A. Al-FredanA variety of environmental factors are known to modify the toxicity of heavy metals on algae. This study was undertaken to examine the impact of some inorganic and organic complexes on the toxicity of copper using the isolated algal species (Chlorella vulgaris). The data illustrate that the amount of available forms of copper (copper free ions) gradually decreased with increasing … …American Journal of Environmental Sciences, Vol. 8, Issue 6 · 2 Jan 2013 · 6,764 accessesView PDFCite
Review ArticleOpen accessIn the abstractDisinfection of Water using Supported Titanium Dioxide PhotocatalystsShamkumar Pandurang Deshmukh, Dattatray Krishna Dalavi, Yuvaraj Mohan HungeTiO2 based photocatalyst has potential material for disinfection of harmful pathogens as well as removal of organic compounds. The formation of reactive oxygen species is a key part for overall process but aggregation and band gap constraint explore a new dimension to use of support for propounding its physicochemical properties. Therefore, the modification of TiO2 using various support alters photocatalytic … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 4 · 28 Dec 2020 · 7,266 accessesView PDFCite
Research ArticleOpen accessIn the abstractSpecific Features of the Accumulation and Distribution of Heavy Metals in Soils of the Floodplain and Deltaic Landscapes of the Don RiverTatiana M. Minkina, Dina G. Nevidomskaya, Yuriy A. Fedorov et al.The purpose of this work was to study specific features of the accumulation and distribution of the total content and mobile forms of Heavy Metals (HM) in soils of the estuarine ecosystems of the floodplain and deltaic landscapes of the Don River. The results allowed us to detect regional specific features in the formation of HM compounds in floodplain soils … …American Journal of Applied Sciences, Vol. 12, Issue 11 · 19 Nov 2015 · 6,593 accessesView PDFCite
Research ArticleOpen accessIn the abstractStudy of Heavy Metals in the Surface Sediments of the Main Wadis in the Region of Meknes-MoroccoA. Lammini, A. Dehbi, H. Omari, A. AbdallaouiBecause of their growing demographic and industrial expansion, the urban areas of the city of Meknes are likely to disturb the ecological balance of watercourse. In the present work, we had evaluate the degree of sediment’s contamination by heavy metals (Al, Cd, Cu, Fe, Mn, Pb and Zn) in the main wadis of the Meknes region (Boufekrane, Wislane and Toulal) … …Current Research in Geoscience, Vol. 4, Issue 2 · 29 Apr 2015 · 7,112 accessesView PDFCite
Research ArticleOpen accessIn the abstractINFLUENCE OF INCUBATION PERIOD, TEMPERATURE AND DIFFERENT PHOSPHATE LEVELS ON PHOSPHATE ADSORPTION IN SOILA. Rajput, Q. A. Panhwar, U. A. Naher et al.Phosphorus (P) is the most important element after nitrogen but P sorption properties are poorly documented in many soils. In this study, P sorption capacity in relation to incubation period and temperature under various P levels were determined for two different soil series (Rustam and Miani). Phosphorus was added at 5, 10, 25, 50, 100, 250, 500 and 1000 µg … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 2 · 13 Feb 2014 · 8,294 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Review of Acetol: Application and ProductionMohd Hanif Mohamad, Roila Awang, Wan Md Zin Wan YunusProblem statement: Acetol is used as organic intermediates because it contains both hydroxyl and carbonyl functional groups and mainly use to produce polyols and acrolein. It also widely uses as reduced dyes and skin tanning agent. The commercially used acetol is made from petroleum-based that leads to high cost of production.
