This paper discusses the methodology used to determine the optimal ion-exchange column size to process all separate batches of feeds from acid mine drainage wastewater. The optimal design ensures the best utilization of resin material and therefore results in a minimum amount of spent resins. Ion exchanger materials have been studied for removing heavy metals from a metal bearing wastes. For th...
In ancient Greece, "terra sigillata" or "sealed earth" was reputed to be a successful counter agent for poisons (1). Its fame grew through the centuries commensurately with the refined custom of poisoning one's dinner partner. Early trials of the effectiveness of "terra sigillata" are reported in two 16th century documents (2). The first, dated 1580, records that of eight dogs who were fed vari...
Capacitive deionization (CDI) technologies have the potential to become cost-competitive alternatives reverse osmosis for treatment of brackish waters. In this study, we report our findings on effect co-ion sorption and faradaic side reactions ion exchange resin functionalized desalination electrodes which passively capture salt reject it upon charging. This system, previously reported refer as...
The occurrence of 5-hydroxytryptamine (serotonin) in normal human urine is suggested by the experiments of Page and his co-workers. Twarog & Page (1953) examined acetone extracts of urine by a pharmacological method (isolated heart of Venus mercenaria) and reported a 'serotonin-like activity' equivalent to 0'1-10yeg. of 5-hydroxytryptamine/ ml. ofurine. Later, Bumpus&Page (1955) described indol...
background: in this study we have prepared the iga solution from normal human plasma using plasma fractionation and ion exchange chromatography. materials and methods: using fractionation of plasma with cold ethanol (starting with 8% ethanol), fraction iii was prepared as a suitable source for iga preparation. then it was treated with caprylic acid for separation of impurities. for enrichment o...
The newly synthesized Guar gum Diamino Benzoic Acid (GDABA) resin for elimination of hazardous waste metal ions was developed from industrial effluents. gaur has been studied their good sorption properties and found to have potential management. In the laboratory, chemically produced derivative employed Pb2+, Cd2+ Zn2+ effluents Steel Industries in Jodhpur, Rajasthan (India). These groups ion e...
The production of (82)Sr at iThemba LABS is performed by the proton bombardment of a RbCl target using the facility's Vertical-Beam Target Station (VBTS). (82)Sr is separated from the target material using a method based on target dissolution, using dilute ammonium chloride solution, and the use of chromatographic methods on Purolite S950 ion exchange resin. After performing a further purificat...
Ammonium is one of the main factors responsible for eutrophication water bodies. Purolite SSTC60 ion exchange resin was used to investigate its potential use on ammonium removal efficiency. The effects important parameters affecting such as dosage, initial solution pH, temperature, mixing speed and concentration were investigated. highest achieved at pH 7. It determined that rates increased wit...
A simple and sensitive suppressed ion chromatography (IC) method with conductivity detection for the determination of molybdate in environmental water is proposed. Molybdate in highly saline water was extracted and preconcentrated. Preconcentration was accomplished by using a chelating resin using a chelating resin immobilized with carboxymethylated polyethylenimine (Presep(®) PolyChelate). Thi...
