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...

Adsorption techniques are widely used to remove the pollutants from waters, especially those that are not easily biodegradable. The removal of crystal violet dye (CVD) from water was studied by using Amberlyst 15, a cation-exchange resin (CER), along with Ferrous (Fe 2+ ) and H2O2 . In this study the main factors that can influence the degradation of crystal violet dye are molar ratio of [(H2O2...

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...

Perchlorate (ClO(4)(-)) is a persistent contaminant found in drinking groundwater sources in the United States. Ion exchange (IX) with selective and disposable resins based on cross-linked styrene divinylbenzene (STY-DVB) beads is currently the most commonly utilized process for removing low concentrations of ClO(4)(-) (10-100 ppb) from contaminated drinking water sources. However, due to the l...

ION EXCHANGE RESIN AS AN IMPOSING METHOD FOR TASTE MASKING: A REVIEW A. M. Suthar* and M. M. Patel Saraswati School of Pharmacy, Ranela, Gujarat, India Kalol Institute of Pharmacy, Kalol, Gujatat, India ABSTRACT Taste masking becomes a pre-requisite for bitter drugs to improve the patient compliance especially in the pediatric and geriatric population. Conventional taste masking techniques such...

[18F]Fluoride for nucleophilic radiofluorination was recovered from target water by trapping on a fibrous anion exchange resin in the hydroxide form and subsequent displacement into wet methanolic K2CO3. Extraction into methanol facilitated rapid evaporation and resolubilization of the [18F]fluoride as an ion pair. The resin was first dried in situ and rehydrated with [18O]H2O to avoid isotopic...
